Hi, My Micro's power supply blew and I wanted to be in a fullsize cab anyway. Can I bolt my Micro/PDP11 Q22 backplane into an 11/03 chassis easily? Anyone know about feasibility / gotchas before I start experimenting? thx jake

Purchased a Microvax 3800

by lyokoboy0＠gmail.com

I got the power cord for the microvax 3800 in the mail today. I checked the fans as someone suggested, they Spin nice and smooth. I Iooked over everything, nothing seems out of place. I powered the machine on. Very quiet. I expected it to be much louder. I turned the machine on and nothing exploded. The KA660 cpu board has that little red lcd display ion it. A F is displayed. Not sure if that is normal or not. I need a console cable. I have a vt100 that works over here. What is the cable called, is it something i could buy, or is it something that is easy enough to make? --Devin On Tue, Dec 8, 2015 at 3:37 PM, devin davison <lyokoboy0 at gmail.com> wrote: > "So a 9-track open-reel SCSI drive should work just as well as a DDS, > DLT, SLT drive." > > Oh wow. i had not even considered that.

Source for DEC DC005 bus drivers.

by mattislind＠gmail.com

I just recently had a RXV21 board that I inserted into the backplane and then completely hung a few bits on the bus. It was a DC005 bus transceiver chip that had failed. First it seemed impossible to find such a chip, but then I recognized that Signetics had put their own code own them as well, C2324N. Searching on Ebay gave this result: http://www.ebay.com/itm/281679682476 I bought some and they just arrived and worked perfectly. /Mattis

QIC Tape help with CRC - Dwight?

by microtechdart＠gmail.com

While I'm new to speak up here, I've been watching for a while. I've also used the name "MightyFrame" on groups, although that email address is not registered with this list. A few months back, I published a page decoding QIC-24 format. http://mightyframe.blogspot.com/2015/08/qic-24-tape-data-block-format-decod… Dwight posted a very meaningful response to this about the CRC on my site, and it has taken me this long just to get to it. Thanks again for that, Dwight! This project has gone very well for me, with one hangup...the CRC. I've never calculated one of these before, and I'm struggling with this one. I have a QIC-24 block of data attached in a .txt file, and I just can't get the calculations to work. For my simple understanding so far, I'm using an online calculator to test this: http://bit.ly/1YbHUZ7 That URL is pre-programmed with the polynomial and the "message" that should provide the CRC result of 0xE8CE (decimal 59598) But, it doesn't. I created this file, wrote it to tape, then read it again and tested it. It is 100% correct for the QIC-24 tape system. This is block 3 of 4 of the file that I have extracted, and am testing here. The ANSI QIC-24 standard booklet (X3.136-1986) says something that I know is a clue, but I just don't understand. "The cyclical redundancy check (CRC) shall consist of two bytes, calculated over the 512 bytes of interchange data, and the 4-byte block address, *starting with all ONEs, CRC initial value*, and using the CRC Generating polynomial: x16 + x12 + x5 + 1 *"starting with all ONEs, CRC initial value"*? What does THAT mean? Do I need to do some kind of register shift? xorin or xorout? I've even played with http://reveng.sourceforge.net/, but I'm having trouble even understanding the meaning of the input values and parameters with this. I appreciate any feedback that anyone can give, here. -- Thanks, -AJ http://MicrotechM1.blogspot.com http://MightyFrame.com

Four-phase non-overlapping clock generator using PIC microcontroller

by spacewar＠gmail.com

In the 1970s, some microprocessors and support chips used four-phase NMOS logic. Some, including the Rockwell PPS-4 and PPS-8, generated the four non-overlapping clock phases on-chip based on two external clock inputs, while others, including the TI TMS9900, the Western Digital CP1600 chip set (used in DEC LSI-11 and Alpha Micro AM100), and the WD9000 chipset (used in Pascal Microengine), required an external four-phase clock generator. Typically the four-phase clock inputs required a voltage swing close to the Vss and Vdd supply rails (0 to +12V). TI and Western Digital offered support chips to generate the four-phase clock, although it was often done with a crystal, 74S logic, and MOS drivers such as the National Semiconductor MH0026 dual MOS driver or the Intel 3245 quad MOS driver. I've recently had occasion to work on interfacing to some of these old chips, and wanted a modern four-phase clock generator. I've just written and tested code to use a Microchip PIC16F1575 as a clock generator, though it only has 5V outputs, so it will require external gate drivers, such as a Microchip TC4469 quad gate driver, to obtain the 12V swing. The PIC16F1575 is a fairly new part using Microchip's enhanced midrange core. It is in a 14-pin package, has an internal oscillator, PLL, and four 16-bit PWM modules. The PWM modules can operate independently, but for this purpose it was convenient that they can be synchronized. I've configured the PIC to use the 8 MHz internal oscillator, with a 4x PLL for a 32 MHz clock going into the processor and the PWM modules. The CPU speed doesn't matter, but that gives timing resolution of around 31ns for the PWM. I've configured the PWMs for a period of 16 clock cycles (500 ns, 2 MHz), clock high pulses of three clock cycles (93ns), and delay between phases of one clock cycle (31ns). This could be trivially changed to a 2.67 MHz clock by reducing the period to 12 cycles and hte clock high pulses to two clock cycles (62ns). Either set of timings is within the specifications of the TI and Western Digital parts. A word of caution: when using gate drivers to drive old NMOS parts, I recommend the use of series resistors of at least 10 ohms and schottky diode clamps to Vss and Vdd, to ensure that undershoot and overshoot (due to ringing) are limited to 0.3V. The C source code is released under the GPLv3 license on github: https://github.com/brouhaha/4phaseclk

DEC MM15 core mem found

by j_hoppe＠t-online.de

I help cleaning out a large repository of DEC parts. There a quantity of DEC core module assemblies appeared. According to PDF docs these must be PDP-15 MM15's, but no labels are on the boards. I show/offer some of them at retrocmp.com/flipchipshop , under "core memory" Can somebody confirm they are MM15's? Are any PDP-15 running at all? Thanks, Joerg

CDC Finch Alternatives Today [WAS:RE: Evotek Winchester Harddisk]

by t.gardner＠computer.org

The manual u cited states, "The disk controller can control either a CDC or Finch drives. All drives attached to any controller must be of one type." I'm not sure what they mean by "CDC" but if u are lucky it might mean "SMD." According to the 1983 Disk/Trend Finch interfaces were available on the Wren 9415-32 (Finch and ST506) and the Wren 94153 (Finch only). So u might look for a 94153 or a Finch variant of the 9415-32. The Finch spec data interface specs include 13440 unformatted bytes per revolution using an 806 KB/sec data rate, which are the very old at that time 3330 industry standards. There are very few small drives that use this standard, not even the 94153 (10,080 @ 605 KB/sec) so what happens with the drive at a different frequency and the controller with a possibly a different number of raw bytes per track is unpredictable. Note that 10080 x 806/605 is close enough to 13440 so any 10,080 @ 605 KB/sec drive might be made to work if the recording channel has margin at the higher frequency; unfortunately there are not very many. A bigger problem might be the command and control interface of the Finch - it is not like the ST506/412. Off the top of my head it looks like a variant on SMD. BTW SMD data specs are exactly 1.5x3330, that is 20,160 bytes @ 1.209 MB/sec so a small SMD might work if the recoding channel can deal with the lower data rate, perhaps the 8715 FSD. You might want to compare pin by pin SMD to Finch to see if this is even possible. There were some small SMDs, e.g. Micropolis 1403, Priam 804 but most were 14-inch. Perhaps there is a CDC SMD expert in this group that can help Tom -----Original Message----- From: Oliver Lehmann [mailto:lehmann at ans-netz.de] Sent: Monday, December 07, 2015 11:39 AM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: Evotek Winchester Harddisk Tom Gardner <t.gardner at computer.org> wrote: > Sorry If I didn't make myself clear, I am suggesting one never acquire > an Evotek drive today other than perhaps as an historical curiosity. > > > > The Finch was a short lived 8-inch HDD that went up to 42 MB > unformatted BUT according to Disk/Trend It did not use an ST506 > interface but instead came with this variety of interfaces: Finch, > LDI, SMD or SA1000!

The newest one acquired is a PERQ-1 (and it is in good condition...boots just fine.... ..and just got the report that it booted about a week ago after the chassis with HD arrived) Only problem is we don't know the password for the user (and the guest account is disabled). I know about it, because I rescued it for him out here in Atlanta. And I only rescued it because I had knew Skeezics was a fan from some postings on sun-rescue years ago. I almost gave him a heart attack when I told I had picked it up and it was his, he just had to pay shipping...

When I called the original owner he said this was the last one he had (bummer) but he remembers them fondly (and I was even able to find a picture of one in the history part of his company web site... not sure if it's the actual unit I picked up, but could be... ) I don't believe Skeezics is on cctalk, but he has a number of them. Lots of good stories, his Dad worked at 3Rivers.... Skeezics I beleive also has the OS source and got the last machine that they had left when they closed down. He works on the emulator, etc. and has been chatting with Al about PERQs as well... If you want to see about visiting his collection let me know... Earl the Squirrel

Anyone interested in old (PDP-8 driven) Radio Automation hardware?

by derschjo＠gmail.com

Hi all -- I have recently acquired a PDP-8/m system that was used to drive a radio automation rig (very very similar to this: http://www.bowkera.com/kcbs1.htm ). My understanding is that this system hooked to banks of what were essentially 8-track tape drives, each of which held a short loop of tape (containing a song, an ad, call info, etc.) and the 8/m was programmed with a playlist of sorts so that even in the early 70s you didn't need to have a real DJ on premises to run a radio station. (I had no idea this sort of thing went back that far!) This one was used at KRDU (Fresno's Christian Radio). At any rate, it's neat hardware. All I have is the 8/m, a custom front panel (as seen in the pictures on the site I linked above) and a bank of Omnibus backplanes holding cards that would drive the tapes and mix audio. I really have no use for the tape-control / audio mixing hardware since I don't have the tapes and I'm not *really* planning on running an automated radio station out of my basement (though it does sound fun). I'm not about to scrap the stuff (it's at least useful for parts) but I thought I'd see if anyone out there could actually make use of it for its intended purpose. - Josh

ModemDoctor and Hank Volpe

by cctalk＠fahimi.net

I was wondering if anyone on the list may have contact info for Mr. Volpe the author of ModemDoctor. I attempted to send in the registration fee for his service based on the address on his website. The letter was returned "not deliverable". The site does get occasional updates so he is still around and apparently still accepting orders. Thanks -Ali

Maximizing value selling a working 11/34

by jnc＠mercury.lcs.mit.edu

> I seriously doubt the splitting of the H960 from its feet or not will > influence the outcome of a job position. I don't know, because I don't know enough about their exact financial state. But it doesn't matter, for two reasons: First, given that it's for a good cause, it shouldn't matter; it will help, that's all one needs to know. Second, even if it weren't for a good cause, "the splitting of the H960 from its feet" is - or should be - No Big Deal anyway. It's not like the parts are going to be melted down, or anything; they will just be re-arranged. So someone who has e.g. a three-bay system, with feet on the two end cabinets, would probably be quite happy with a fourth bay without feet. And at the same time, someone who has a one-bay system with no feet would probably be ecstatic to finally find feet. Everyone's happy, all the parts are in good homes; where, exactly, is the problem?

Looking for AS/400

by fink＠stenoweb.net

Hi there, Recently, I've been reading up into AS/400s.. They seem like really neat machines, and look really sharp with those matching block terminals. I remember retail stores using those, and I always wondered what kind of a system they were running on... I figured it was DOS! I've been having trouble locating one, however. Anybody have one lying around, or know of where to find one in the Toronto area? It needn't be a high spec machine, just something to play with OS/400 and a terminal. Thanks! -brian

Pair of PDP-11/04's available

by jnc＠mercury.lcs.mit.edu

So I've been informed that a pair of PDP-11/04's are available, Chicago US area. The price isn't set - someone else has offered the owner ~$400, which seems a bit low to me (although I don't know what peripherals/memory are included, if any). One is in a 5" box, and one in an 11"; both apparently include the basic "Operator's Console" (i.e. halt and reset toggles). Contact Patrick Lynn at 815-838-0134 if interested. Noel

PT-210 Serial Board

by dave＠661.org

A few years ago I entered the schematics and laid out a design for the serial board option for the TRS-80 PT-210 printing terminal using gEDA. I found the schematics in a hardcopy of the service manual[1]. I revisited the project a couple of days ago and reentered the schematics into Kicad. I remembered that the reason I never made the board was that I was unsure of its correctness. The schematics and foil patterns contradict slightly and a couple wires seem to be missing from the schematic. Does anyone here have a PT-210 with a working serial board? I would like to work with you to beep out various points so I can figure out what's wrong. I also found a Youtube video showing a PT-210 with the serial board in action. See https://www.youtube.com/watch?v=FPxpzcFXh-0 [1] Scanned and uploaded to http://chiclassiccomp.org/docs/content/computing/RadioShack-Tandy/ -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text.

80186 multi buss system problem

by grant＠millhouseindustries.com

Hi, I?m looking for some help diagnosing a old Grid server problem,I am a hobbyist learning my way around old computer systems . The system consists of three boards labeled Diagnostic server File server Com server Each board contains a 80186 , ram and rom and are all connected via a backplane. The diagnostic server has rs232 port and a connector to a small led display. The file server has a GPIB port and a something along the lines of a SASI port The com server has what i believe to be several rs232/422?s ports at least What i know works is the diagnostics server and the file server as i can interact with the diagnostic server via a serial terminal and the file server attempts to boot from a gpib floppy but i have no boot media that will boot it. The problem is with the com server board, when the system initializes the diagnostic board does a self test then looks for other boards on the system it finds the file server board but does not find the com server board. If i remove the the file and com server and power them out of system, reset the processor?s and then probe the different signals they appear to be operating the same,clk activity , data and address buss activity is identical. When i put them in the system and watch the file and com server boot it looks like the com server get stuck when it goes to send its data to the diagnostic server. I'm just a amateur at these things, i am looking for help to point me in the right direction. i made a small video of a typical data line at boot the first is the file server then the com server where you can see it get stuck , this is typical of all the signals that i test. https://www.youtube.com/watch?v=jHftWR0Ddys&feature=youtu.be --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Random question about a Byte Magazine Cover

by mark＠wickensonline.co.uk

OK so this has been bugging me for a while. During a stint working at Morgan-Smith Electronics in Hatfield UK (they made diverse electronic systems including industrial PCs and radio alarms) I went through the boss's discarded vintage computer magazine collection and one particular issue I remember finding very interesting. IIRC it was a Byte Magazine (certainly the graphic was very in keeping with Byte cover artwork). I wonder if anyone recalls it - Google image searches have pulled a blank which means it either wasn't Byte (and just looked like it) or hasn't been scanned. The cover had a painted image of a white cliff face draped in vines with an 'Adventurer' in the foreground - you can imagine what the theme was. Anyone have any ideas? Maybe it wasn't Byte? Of course all this really quite irrelevant in the grand scheme of things, but it would help me scratch an itch at the very least. Thanks! Mark.

Project Oberon and OberonStation (resend)

by wmaddox＠pacbell.net

[Yahoo's webmail client garbled the last link -- resending] The revived 2013 re-issue of Niklaus Wirth's Oberon system is a joy to behold.? If you've never heard of Oberon before, it is a minimalistic education-oriented language and operating system designed after Wirth had taken a (second) sabattical at PARC in the 80's. The new version runs on a custom RISC processor, implemented in an FPGA, instead of the NS3032 in the orginal Ceres workstations.?? Originally, it required a Digilent "Spartan 3 Starter Kit" with a custom-built daughterboard providing a few additional connectors.? This board is no longer made, however, and no other FPGA development board appears to provide the 32-bit wide fast SRAM the Oberon CPU required. Recently, a new board, the OberonStation,? has come onto the market that was designed specifically for Oberon, and will boot up Oberon 2013 out of the box.?? It also looks like an excellent platform for other retro-style FPGA CPU designs that want to stay away from complex SDRAM controllers and the caches they like to feed. My OberonStation arrived a couple of days ago, and it's really amazing to see what can be done with a hardware and software stack that is small enough to actually read and understand. https://www.inf.ethz.ch/personal/wirth/ http://www.projectoberon.com/ http://oberonstation.x10.mx/

Purchased a Microvax 3800

by lyokoboy0＠gmail.com

I purchased a Microvax 3800 a few weeks ago. I have not really had the time to really take a good look at it until now. I still do not have the needed power cord to power it Up. Looks like a standard PC power cord with a notch in it. I found a place that sells them online, still waiting for it to get here. I was told the machine was removed from working service, however it looks like it has been sitting for quite some time. The hard drive, hard drive controller, and tape controller have been removed. I purchased a m7769 DSSI controller card online, so that is one more step in the direction of getting the machine all together. Still waiting to find the controller for the tape drive and a dssi hard drive, although they look to be pretty affordable on ebay. Just figured id post about it here, to show my progress twords getting it running. http://postimg.org/gallery/fztxjqbe/ --Devin

double density floppy cable adapter for Intel Series II or III MDS

by spacewar＠gmail.com

Last month I made a trivial little cable adapter PCB to use with the Intel SBC 202 double-density M2FM floppy controller in an Intel Series II or III MDS (normally part of an MDS 720 subsystem). The usual SBC 202 cabling has two DC37S connectors on the MDS back panel, one for drives 0 and 1, and the other for drives 2 and 3. (There's a variant that has a ribbon cable to the internal drive as 0, and only one DC37S for drives 2 and 3.) Photos: https://www.flickr.com/photos/22368471 at N04/albums/72157659736489274 Schematic and board layout in Eagle and PDF: http://www.brouhaha.com/~eric/retrocomputing/intel/mds/mds-fd-adapter/ The adapter has no active electronics; it just wires a DC37P to a 50-pin header for a cable to one or two normal 8-inch floppies. I just got around to testing it yesterday, and was pleasantly surprised that my SBC 202 and the adapter worked on the first attempt. The SBC 202 was of unknown provenance so I didn't actually have much expectation of it working. I haven't yet tried more than one drive on it. Intel used radial ready signals from the drives, so the drive(s) have to be configured slightly differently than the factory defaults to be fully compatible with the MDS 720. I have one spare bare adapter PCB which can be made available for $5.95 plus shipping from Colorado if anyone else needs such a thing. I am NOT willing to source the connectors or assemble the boards. You can also order them in increments of three pieces directly from OSH Park: https://oshpark.com/shared_projects/AO0DZTr1 If there's demand for a few units, I can have a small run made in China very inexpensively, probably under $4 each plus shipping from Colorado. Richard Main has made fancier adapter PCBs that also support 34-pin cabling for the use of high-density 5.25 or 3.5 inch disks.

Memory Voltage on MicroVAX II

by robert.jarratt＠ntlworld.com

I finally fixed my H7864 PSU so I can now run my rtVAX 1000. However, I think the machine is damaging memory boards. I checked the ripple and 5V looks OK, but 12V looks suspicious. Is the 12V supply used by the memory? Incidentally, as I have mentioned before, I have drawn out the schematics for the H7864 PSU. The schematics are drawn illogically, with mistakes almost certainly still there, but the Primary side I think is more reasonable now. Is there a good place to post these? Regards Rob

Announcing CBM15 V012 (new Beta release)

by drlegendre＠gmail.com

CBM15 V012 has been released to CSDB, and is currently available for download. http://csdb.dk/release/?id=143468 CBM15 is a telecommunications software, that facilitates direct two-way communications between a Commodore 64 computer and a Teletype Corp. M15KSR (or any other compatible machine). Note that CBM15 follows the 5/N/2 serial protocol, at a fixed line speed of 45.45 baud (22mS signalling period). As with any of these PC-to-TTY setups, an external RS-232 to Current Loop converter is required. This is an initial release, and upcoming releases will add new features and correct a bug or two. So.. am I the only one on the list(s) with a C-64 and an M15 on hand? If you have the required hardware, please give it a try - so far, I've had no feedback from any other 'real' M15 owner.. Thanks!

PDP-12 Restoration at the RICM

by michael.99.thompson＠gmail.com

I used my PDP-8/e at home to test the RX8E controller and the RX01 floppies that came with the PDP-12. Both worked OK. We found a bad SP380 on a M7102 board in the DW8E the Omnibus expansion chassis. This would not let the SKIP instructions work with the RX8E, RK05, or PC8E. Once we replaced the SP380 we were able to boot OS/8 from an RX01 floppy. This may be the only PDP-12 to ever do that. -- Michael Thompson

[multicians] Emacs humor

This is a funny cartoon and subsequent discussion thread from the Multics discussion group about emacs. Names and personal info edited out due to archival by unknown parties of the list and that these folks might not want names and certainly not email addresses archived. Mentioning that not as a criticism, just to explain the format. I also edited the thread back to bottom posting. Original XKCD cartoon link. https://xkcd.com/378/ >> From: Multicians <snip> >> Subject: Re: [multicians] Emacs humor >> >>> >>> >>> Thanks, Gary. As an emacs diehart, I fully appreciate that. In fact, there is a silly phrase that many emacs users use, when referring to all the obscure key bindings that you get by default with emacs, or can create.

It was developed on Lisp machines, which sported lots of modification keys on its keyboard. These included Control, Shift, Hyper, Meta, Super (and perhaps more). Naturally, emacs took advantage of some of these . at least those that were available on multiple terminals or could be emulated on lesser terminals. I remember when I worked at MIT LCS (down the hall from MIT AI), we had a key binding on our Lisp Machines that called the elevator to the 8th floor. I don.t remember the key binding, but I.m sure it used a few of these modification keys (and probably .e. for .elevator. as the modified key). In any case, the class of these funky key bindings was referred to as Control-Meta-Shift-Cokebottle. >>> >>> I.m sure I.ve gotten some of the facts wrong, but I.m also sure that at least someone on this list will correct me! >>> >>> .

Some AI Lab hardware guys gained access to the machinery room on the 10th floor and added some extra relay circuitry to one of the elevator controllers, and it wasn't much of a stretch to run the control wires down to the 9th floor machine room.

Fabritek MP-12 Loader

by kylevowen＠gmail.com

A colleague and I are working on getting our respective Fabritek MP-12s working. The MP-12 is an industrial-looking computer with a very limited front panel (deposit doesn't increment PC...gah!) but does emulate most respects of a PDP-8. So far, we've been able to find the device codes for updating the 7-segment LED displays on the front, turning on and off relays, and setting some arbitrary open-collector outputs. It appears as though there is no serial port option on ours, which is unfortunate. There are three 512-by-4 bipolar (configured as 512-by-12) PROMs that seem to override the core memory at the top of the 4k field. If the PROM's value is 7777 octal, the core memory is accessible. Otherwise, you're stuck with ROM, best I can tell. We've dumped the ROMs to verify, but here's the code I've backed out of them, disassembled and labeled where appropriate: *7756 TEMP, 7755 /NOT IN ROM CLA HLT /7602 ADDR, 7755 /7755 STARTING ADDRESS? START, TAD ADDR /1360 GET STARTING ADDRESS? DCA TEMP /3356 SAVE TEMPORARILY LOOP, RRB /6012 GET CHAR CLL RTL /7106 RTL /7006 RTL /7006 ROTATE SO BIT 0 IS IN BIT 7, BIT 4 IN BIT 11, ETC. 6015 /6015 SKIP ON FLAG? JMP .-1 /5367 SNL /7420 SKIP IF LINK IS SET (BIT 6 OF PAPER TAPE IS SET) JMP LOOP /5363 DCA I TEMP /3756 ISZ TEMP /2356 JMP 7755 /5355 7776 /NOT IN ROM JMP START /5361 $ The "NOT IN ROM" indicates that the ROM's value is unprogrammed, so that you can in fact access those core locations. The values I've provided just happen to be what's in my machine's memory at this time. It looks a lot like a RIM loader, except I can't figure out for the life of me what the format should look like. Best I can tell, if RRB ORs the read buffer with the accumulator, you'll never be able to send anything but patterns matching (data & 7737). At least, that's what I've simulated. Due to the fact that they're clearing the link after the second go around, you'd be losing one bit of data. So, maybe this isn't really a program loading routine, but rather just something to store 8-bit values in core? Any other ideas? Thanks, Kyle

Dear List While the silk screeners process the panels I have a couple of days for a little project I have a TU-58 and yes it had gooey drive wheels. Now it no longer has that problem but I have black and gooey fingers.!!! I know this issue has been addressed before. So I think somebody must know where I can get the right tubing to replace the degraded stuff. The drive hub is 0.42" and the rubber bit was 0.62" o/d A UK source would be nice, Rod

Long shot: Connection Machine board needed.

by tmfdmike＠gmail.com

The chances are slim, but someone may know someone... feel free to contact me off-list. I have a CM-200A; the smallest 'classic' CM machine. I've started a project, with some ex-TMC people (notably the designer of the beautiful chassis the CM machines came in, Tamiko Thiel) to get my machine operational next year, for the 30th anniversary of the launch of the CM. Unfortunately we've hit a complete show-stopper right off the bat. My machine has a complete set of compute node and I/O boards, but is missing the crucial 'NX' board; the board in the CM that interfaces to the front-end. See: http://www.corestore.org/cm2a.htm I need to locate one, or we're dead in the water. I *know* there are people out there who keep a very low profile and have CM hardware squirreled away in their basements. Another possibility, perhaps the best, is to *borrow* an NX board from a non-functional machine in a museum collection, something that will never be more than a static exhibit. Anyone in a position to help or advise, please get in touch. I'm reaching out to former TMC staff and customers by various other routes, but someone here may know something. Thanks Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother. Not for millions, not for glory, not for fame.

Help w/ HP 88780 Tape Drive

by cctalk＠fahimi.net

So I got my hands on an HP 88780 1/2" Tape Drive from list Member Mark (Thanks!). The drive physically looks to be in good shape but was pretty dirty when I got it. I've cleaned up the drive and powered it up. The good news: The drive powers up. Initially I had trouble getting it to load a tape but that seems to have been resolved.

PDT-11/150 Field Maintenance Print Set wanted

by spacewar＠gmail.com

I have a non-working PDT-11/150, which fails self test 7 (console USART) and when not in test mode, and with autobaud disabled, doesn't send anything to the console. I dumped the ROMs (two 82S2708 1Kx8 PROM for LSI-11 code, three 8316E 2Kx8 masked ROM for the 8085 I/O processor, and one 8316E for the 8085 floppy controller), and I've started disassembling the 8085 ROM code to figure out what the self-test actually does, but it's slow going. It would be really helpful to have a copy (paper or scan) of the Field Maintenance Print Set. Does anyone have it? Thanks! Eric

Oberon and the OberonStation (retro-style FPGA computing)

by wmaddox＠pacbell.net

The revived 2013 re-issue of Niklaus Wirth's Oberon system is a joy to behold.? If you've never heard of Oberon before, it is a minimalistic education-oriented language and operating system designed after Wirth had taken a (second) sabattical at PARC in the 80's. The new version runs on a custom RISC processor, implemented in an FPGA, instead of the NS3032 in the orginal Ceres workstations.?? Originally, it required a Digilent "Spartan 3 Starter Kit" with a custom-built daughterboard providing a few additional connectors.? This board is no longer made, however, and no other FPGA development board appears to provide the 32-bit wide fast SRAM the Oberon CPU required. Recently, a new board, the OberonStation,? has come onto the market that was designed specifically for Oberon, and will boot up Oberon 2013 out of the box.?? It also looks like an excellent platform for other retro-style FPGA CPU designs that want to stay away from complex SDRAM controllers and the caches they like to feed. My OberonStation arrived a couple of days ago, and it's really amazing to see what can be done with a hardware and software stack that is small enough to actually read and understand. https://www.inf.ethz.ch/personal/wirth/ http://www.projectoberon.com/ OberonStation - The Oberon computing platform --Bill | ? | | ? | ? | ? | ? | ? | | OberonStation - The Oberon computing platform/*{{{*/* html .tiddler {height:1%;}body {font-size:.75em; font-family:arial,helvetica; margin:0; padding:0;}h1,h2,h3,h4,h5,h6 {font-weight:bold; | | | | View on oberonstation.x10.mx | Preview by Yahoo | | | | ? |

>> I think the elevator hack involved the AI Lab PDP-6 (or maybe, later, >> PDP-10) I can supply definitive bits here (I have read the code involved). The actual interface to the elevator was in one of the PDP-11 front-ends on the MIT-AI KA10 (memory escapes me as to whether it was the TV11 or the XGP11 or what, don't have time right at the moment to go look - I suspect the former). There was actually a table in the PDP-11 code that ran the Knight TV's (perhaps the first bit-mapped display system) so that one only needed to type '<Whatever>-E', and the code knew which floor that Knight TV console was on, and automagically sent the elevator to that floor (3, 8 or 9). >> I wouldn't be surprised if it migrated to the Lisp machines, too Yes, but that would have just been a network client talking to a server; the actual hardware interface remained, I am pretty sure, on the -11.

So first you need permission to use that! I will try and figure out who the person was that first used that phrase so we can both use it. I did not mention that the concept worked quite well with the DEC RX02 and the DSD RX03 when a PDP-11/73 was used. But when version 1.0 of that device driver was used with a PDP-11/23, the transfer rate was painfully slow because the interleave gap was not long enough relative to the time needed to bounce the buffer. Since the DMA silo had already been emptied into the bounce buffer, the solution was to immediately initiate the next READ into the silo and then bounce the buffer (for a READ request, of course). That allowed the READ of the next sector on the floppy media to be performed by the controller while the CPU was performing a transfer out of the bounce buffer into the user buffer one word at a time. I don't need to test the timing on any slower CPU since, as far as I know, none support an MMU which would be required to use a Mapped RT-11 monitor. I may have the exact details and terminology incorrect - it was about 20 years ago. Jerome Fine

PDP 8 Timesharing

by rickb＠bensene.com

Hi, all, Just figured I'd post something about my tinkering yesterday. I got an M8830 from Paul Anderson. This is the crystal-contolled clock for the Omnibus PDP 8 machines. Yesterday, I had a chance to try it out. First, I checked the power supply pins to make sure no shorts or anything like that and all was good. A quick visual inspection showed no obvious issues. It was already jumpered for a 50Hz interrupt rate, so I went ahead and plugged it into the backplane. Powered the 8/e system up, and ran a few tests from the front panel to make sure the board was responding to its IOTs, and all seemed well. Booted up OS8 from RK05, and mounted up the multos8.rk05 drive via the serialdisk driver. Copied the MULTOS8 .SV files onto my SYS: volume, and although not configured exactly for my system, I figured they'd be close enough. I then stopped the serial disk server, and fired up Kermit on the laptop connected to the second serial port on the 8/e. Then, I typed R MULTOS on the console, and it said something to the effect that I needed to set the date first. I generally don't bother setting the date at boot time, so I set the date to a valid date, and tried again. This time it gave a welcome message. I checked the accumulator, and it was counting off time as it should. I checked the MQ register, and it was static, but then waited for the accumulator to overflow, and then the MQ incremented by 1, as it should. I pressed CONTROL-H on the console terminal and hit RETURN, and there was the . OS8 prompt! I went to the laptop connected to the other serial interface, and since there was no MULTOS 8 password file on the SYS: device, typed CONTROL-H there, got the login prompt, hit RETURN, and low and behold, another . prompt. I played around with it for a while, and found that because of some of the config differences in how MULTOS8 was built on the pack image, some things were acting strange but in general, it definitely was timesharing between the two users. I could run concurrent things on both terminals, and the response was quite acceptable. I intend to make a build of MULTOS 8 to match my system's configuration, and tinker with it some more when I get time. Next I want to replicate the ETOS Timeshare Board (thanks to Vince and Jack for reverse-engineering the board and making a nice schematic!) I'm accumulating parts to build one on an Omnibus prototype board. Once I get that built, then it'll be time to try out ETOS, which uses the improvements in trapping IOTs and dealing with field change instructions that really improve timesharing performance over MULTOS 8. I am also in the process of getting ready to image some old RK05 packs that belong to Paul Anderson that may hold some interesting ETOS stuff. The packs have been sitting around for quite a long time, and the platters are very dusty. They are going to require some good cleaning before they can be put in a drive, but hopefully, once I get them cleaned up, I'll find some good things relating to ETOS. I'll post updates here with my progress. -Rick -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

Ed# I'd *LOVE* to be able to have a real-hardware HP Timeshared BASIC system running here, but alas, those are a lot harder to come by than DEC stuff. I do have a 2000/Access system running under SimH hooked directly to an ASR-33, which emulates the experience relatively closely, but there's nothing like the real hardware. I cut my teeth learning programming on the HP Timeshared BASIC systems starting in 6th grade under the 2000C version. TSS-8 was indeed a timeshare system for the PDP 8, but it was written to run on DECs earlier fixed-head disk drives that are hard to come about today (compared to RK05's). I've heard that someone had made changes to TSS-8 to get it to run on an RK05, but the fact that it's a moving head disk drive versus a fixed head drive that TSS-8 was designed to run under, the poor RK05 gets thrashed pretty hard when timesharing. There are also the Edusystem timeshared systems that DEC developed for the PDP 8, but I haven't looked too deeply into these yet. -Rick

Brian Brikon diskette drive tester

by snhirsch＠gmail.com

I purchased one of these units on eBay and it seems to be working - modulo a few early-80s tantalum caps that went up in smoke. The tester relies on an attached printer to record test results, which are displayed only fleetingly on the front-panel display. Unfortunately it did not come with the printer and I cannot find any information on line. Does anyone have information on this? Is it serial? Parallel? The onnector is a 20-pin, 0.1" DIP header on the rear panel. The tester supplies printer power on a small 3-pin Molex connector. I can probably trace this out on the internal logic board, but thought perhaps another list member owns one of these and can elaborate. I'm also trying to find the manual appropriate to a base Model 723 tester. The one floating around on the net is for an upscale model (723-4M). While there are a number of similarities, I'm running into just enough behavioral difference to make it worth finding the correct docs. There's also a programming and setup "worksheet" document that has not surfaced anywhere. --

HAL DS-3100 ASR

by unclefalter＠yahoo.ca

Just posting here in case anyone not on other forums I'm on sees this and knows something about these. I picked up a HAL DS-3100 ASR terminal. My understanding is these are RTTY devices intended for teletype/radio use. It is ASCII compatible and in fact I can select ASCII and baud rates from a menu. It has a 25 pin male 'MODEM' port on the back. I can't find it now but somewhere I read it complied with an RS-232 standard. I tried hooking it up to my PC with a null modem cable, but couldn't get either to produce anything on their screens. Anyway, just a shot in the dark in case any of you remember these things. I'm not really into HAM stuff, but it's a cool little terminal and I was hoping it could be used/adapted to other tasks. Brad

My first drive was, indeed, the DSD 880/8, if I remember the number correctly, which did have only the 7.8 MB RL02 reduced drive which you just specified. This reply is confirmation and a bit of clarification that the part number was the DSD 880/8 as opposed to the enhanced model, DSD 880/30, which emulated three full sized RL02 drives. Note that both the DSD 880/8 and the DSD 880/30 included a single RX03 floppy drive. And, of course, both also used a dual module as the controller in the Qbus. Also, as is noted above there must have been a controller for the Unibus. Thank you for confirming that the RL02 emulation supported only an 18-bit address. >The Sigma SDC RXV31 controller supported 22 bit DMA. >See 400255-C SDC-RXV31 Floppy Ctrl Man Aug86 > > I saw that model at one point. It was the only one I ever saw, so I did not bother to include 22-bit support in the DYX.SYS device handler - mostly because I would not have been able to test the code. >I used both, but double sided compatibility between the two products was >occasionally spotty.

A check of the DSD 880/30 manual >from 1981 includes directions to modify the DYX.SYS device driver to support double sided operation with V04.00 of RT-11. Inspection of the file, DY.MAC from V04.00 of RT-11, confirms that DEC had code which supported double-sided media and even the CSR specs in the DEC RXV21 controller specifies, as far as I can remember, a bit to determine if the RX03 floppy drive has detected a double-sided floppy in the drive. Note that the DEC RX02 floppy drive did not have that electronics or hardware to detect double-sided media. It is possible that DEC did produce an in-house RX03 drive, but I am not aware of DEC actually selling RX03 drives to customers. PLUS, the code in the file, DY.MAC from V04.00 of RT-11, has bugs (at least in the distribution copy released with V04.00 of RT-11) which would prevent the correct operation of a double-sided media. One other point of interest is that by 1983 when DEC released V05.00 of RT-11, the extra code with support for double-sided media had been removed from DY.MAC. It probably should be mentioned that a different position is used for the index hole for double-sided media (about 1/2" more to the right) as opposed to the location of the index hole for single-sided media. The DSD 880/30 RX03 floppy drive has TWO detection circuits in the two possible positions to determine which media was present in the drive. Because every floppy media that I ever saw has been coated on both sides and could support double-sided operation even if the index hole was in the single-sided location within the cardboard jacket, I experimented with adding the index holes required for double-sided operation and covered up the single-sided index holes. After that worked successfully, I became disappointed that I had to deface the floppy media with the extra holes. The simple solution was to use a DPDT switch and flip the detection circuits so that the RX03 drive would signal a double-sided media what there was a single-sided index hole and the DPDT switch was in the alternate position. To add to the success of that extra switch, the DSD 880/30 supported an off-line LLF (Low Level Format) which, of course, no DEC controller ever supported for 8" floppy media. In answer to the question of support for double-sided media, there are two methods of using both sides of the floppy. One method is to read all of one side, then read all of the other side of the floppy media. The second method is to read both sides of the media for each cylinder, then increment to the next cylinder. Based on the code for DY.MAC which was present in V04.00 of RT-11, DEC choose the former method. It seems possible that if you were using floppy media written via one method and read by the opposite method, there would obviously be some confusion. The SMS-1000 (I hope I have remembered the part number correctly) includes an 8" RX03 type of drive which can handle both single-sided and double-sided media - although the built-in controller is MSCP based and both the internal hard drive and the single RX03 floppy drive are considered DU: or MSCP devices under RT-11. When single-sided floppy media are used, there is no difficulty. However, if an 8" media that is double-sided is inserted and files are written to that floppy, the results can'r be read on the DSD 880/30 using a modified DYX.SYS device driver which supports double-sided operation since it is quite obvious that the MSCP controller in the SMS-1000 wrote both sides of the floppy before changing cylinders. This might have been the cause of the problem between the two floppy drives. I agree it is doubtful, but I can't think of anything else. FINALLY, due to the 18-bit address restriction with all DYX.SYS device drivers under RT-11, I added code to support a bounce buffer that allows the user buffer to be in a 22-bit location, but still be able to support DMA to the silo on the controller. The bounce buffer must be in the first 256 KB of memory, but the device driver performs the extra transfer one word at a time between the bounce buffer and the user buffer if the latter is above the 256 KB boundary.

ISO: DEC M8320 (KK8E, PDP-8/e/f/m Bus Loads)

by derschjo＠gmail.com

Hi all -- I inherited a PDP-8/m awhile back. Actually, I inherited a mostly empty chassis, which I've been slowly populating. I now have everything I need for a working CPU except for an M8320. Anyone have one going spare for something less than eBay prices (or for trade)? While I'm wishing, I could also use a pair of the "top block" connectors for the CPU if anyone has any lying around... Thanks, Josh

8" hard disk storage for unibus 11?

by tmfdmike＠gmail.com

Many moons ago I had a small fleet of pdp-11/04s, pulled out of a research synchrotron. (well, not *literally* out of the synchrotron, they probably wouldn't work if they had been...) They all had disk subsystems made by a company called Baydel; a 19" rack module, half-height like an 11/04, containing an 8" hard disk and power supply, hooked up to a quad-size Unibus card. Emulated a bunch of RK05s. Can't recall the nature of the interface between the card and the drive. Over the years I appear to have carelessly and unintentionally traded or given away ALL the bloody things! Anyone else have one, had one, or know someone who might? I've Googled and there's a deafening silence, apart from me asking the same question on Usenet ten years ago!

Large batch of DEC flip chips

by j_hoppe＠t-online.de

Here's the opportunity to buy&save batches of DEC flip chip modules. It must be several thousands, I estimate the total weight of the boxes to over 100kg. Most are "red" logic series, but other colors are there too. Apparently they are plugged from different machine types, maybe even PDP-10s or -12s. Of course I'm greedy! But while we have a PDP-12 and some DECtapes here, this amount is mostly useless and will occupy much precious space until the end of my days. So question: Is there any reasonable demand for flip chips in the community? And more difficult: any hint about the price I can offer? Thanks for your opinion, Joerg

by dab＠froghouse.org

> For a classic/straightforward programming interface, the Massbus disks (RP04 and successors) are a good choice. That will take you just over 500 MB, if you emulate the layout of the RP07. Current thinking (at least my current thinking) is RK11 first then probably RP11, both optionally extended to support Q22 addresses. Also something we're calling the RQ11 which will be our "native" interface with variable sized disks with a 32-bit linear block address giving 2TB disks for those who are willing and able to write their own device drivers. Finally, most likely the RH11 for some Massbus disks with 22-bit addressing. After that, I'm thinking to call it good and move on to other projects though I'm certainly willing to talk to anyone who has a particular disk controller they want to implement.

Replacing MicroVAX II PSU With a Modern PSU

by jnc＠mercury.lcs.mit.edu

> From: Robert Jarratt > When the power is OK the output of the inverters is low, so the > transistors are off, presumably allowing the signals to float high. > When the power is not OK, the inverters are high, turning on the > transistors and shorting the signal to ground. That is correct. One thing to watch for: in a machine which does not have bus pullups on the backplane (some do, but many, especially early DEC ones, do not), if you run it without a CPU card plugged in (e.g. to test the power supply), BPOK/BDCOK will be at 0V even if the power is OK because there's no pullup to pull it high (unless driven low). This may also affect some of the lights, e.g. the 'Power OK' light in some DEC boxes - it won't come on, even though power is in fact fine, and working. Noel

Replacing MicroVAX II PSU With a Modern PSU

by robert.jarratt＠ntlworld.com

While I look into what is wrong with my H7864, I'd like to use a modern PSU to power my machine (actually an rtVAX 1000). I think I would need to deal with the following problems: 1. Finding the right connectors (ideally, I am sure I could rig up something more temporary). 2. A way to power the fans, which I believe are 15V, perhaps they would run on 12V as I wouldn't run the machine for long periods anyway, or I could just use PC fans. 3. Emulate the DC OK and P OK signals, I suspect these would be simple +5V signals which could perhaps just come from the +5V of the PSU anyway (unless there is a problem with that). 4. The most difficult bit, I suspect, would be the PSU LTC signal , which I believe is some kind of clock. I don't know what the spec of the signal is, but I will get a scope on a working one to see (NB don't want to risk a working PSU on this machine in case it was a problem with the machine itself that caused the first PSU to fail, I don't mind sacrificing a modern PSU if need be). Has anyone done this before? Regards Rob

1980s/1990s 68k C cross (and not so cross) compilers

by classiccmp＠philpem.me.uk

Hi there, I'm working on reverse engineering a radio navigation receiver (surprisingly not GPS, something else... Datatrak if anyone's heard of it) for the purpose of either repurposing the hardware or building up some kind of demo rig. A lot of my effort at the moment seems to be identifying C Library functions and naming them. Ideally, I'd like to identify the compiler and CLib and feed that into the disassembler to eliminate that work. Does anyone know which 68000 compilers were available in 1993, and which could produce ROM code? Or a few? I've looked at Aztec C68K but ruled it out on the basis that the _strlen library function doesn't match up -- this is the one from the ROM: _strlen: movea.l 4(sp), a0 move.l a0, d0 _strlen_l001: tst.b (a0+) bne.s _strlen_l001 sub.l a0, d0 not.l d0 rts Aztec is identical up to the bne, then: sub.l d0, a0 move.l a0, d0 sub,l #1, d0 rts Which is one instruction longer... so it's not Aztec. Other parts of the system apparently used VME-bus modules... so this wasn't a small operation. Anyway, whatever compiler this is, it pulls in Motorola's Fast Floating Point library. Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

WTB Miniscribe 3425 (working or parts donor)

by nf6x＠nf6x.net

I have an aftermarket hard drive system for the TRS-80 Color Computer. It includes a Miniscribe 3425 5.25" hard drive and a Xebec S1410 SASI disk controller. This Miniscribe hard drive has a stepper motor positioner, and Miniscribe actually sprang for an optical track 0 sensor... unlike the 3.5" Miniscribe 20M drive in my first Amiga hard drive system, which simply slammed the stepper against a hard stop to find track 0. I'd like to image this drive with the MFM Reader/Emulator card if I can get it to work. Actually getting the whole system working with one of my CoCos would be even cooler, of course. I have no idea what might be on the hard drive; it was an eBay purchase, back when eBay and I were still on speaking terms. The hard drive is blinking an error code on its LED, reporting that it cannot cover the track 0 sensor. Measuring the sensor pins with a DMM while the drive is powered makes me believe that the optical sensor itself is working correctly. Its output disappears into a Miniscribe-marked, presumably custom IC, so I don't have high hopes of debugging this further within the bounds of my gumption. Interestingly, the interruptor on the external stepper shaft appears to cover the sensor on the final step against a hard stop, so it's not clear why this drive even needs the sensor. Does anybody have a donor Miniscribe 3425 available for sale or trade? The heads can be rattling around in drifts of aluminum filings for all I care, as long as the logic board is somewhat likely to be functioning. Or maybe has one sitting around that they might like to loan to me to image for them, and they don't mind if I risk board swaps after making a valiant effort to get the data off their drive for them first? So far, I've only used my new MFM Reader/Emulator to image and emulate a Tandon TM503 in a Tandy Fifteen Meg Disk System, and it worked wonderfully in that role. -- Mark J.

Hi Guys Ok our front panels are going into production. Meeting went well. We finally worked out how they did the matte layer on the front It appears to be a transparent or translucent white. Its ink base with no colour The effect is like a steamed up window or shower glass panel. It looks a matt grey colour that transmits light but obscures objects behind it. as the panel behind it is black except where the holes are you see a matt black and diffused white light from the lamps are.

(BTW, which expansion of the "MCU" acronym did you have in mind?) > Simulated ethernet to MCU internal network and/or simulated > q/unibus NIC Not sure I entirely follow this? We had talked about eventually writing code to support a common USB Ethernet interface, and have the QSIC emulate the Interlan NI2010 etc cards, which were very nice to program (unlike all the DEC native Ethernet interfaces). > Block device access to "unmounted" flash partitions Like I said, plug the storage unit (we don't have any that are physically built into the QSIC) directly into the other machine. The QSIC is not intended to provide an SD port for some other kind of machine that doesn't have a native SD port; you can justq buy an SD carrier that is a USB device. Sorry, I'm just not into the whole 'desert topping / floor wax' concept (and a tip of the hatly hat to Marshall Rose for the phrase). 'Can do something' != 'good idea to do something'!! > I suppose "host" ports can used to support physical USB dongles of > various sorts (serial, ethernet), but I guess my orientation is "why > connect extra hardware that can be simulated?" Simulated, how? It's not clear that it's easier to do the simulation (via some complex lash-up) than have the QSIC provide something that looks, programming-wise, just like the DEC originals. Although there are no plans to to serial lines. In general, my philosophy is not to provide things which are still _readily_ available for real - and serial lines fall into that cateory. > ability to halt/reset the q/unibus (PDP-11) processor > (making the MCU into a "front end") If the LSI-11 console is i) plugged into something else, and has 'halt on break' enabled, you pretty much already have that. > If it's possible to make a board that's operable without an MCU Huh? The QSIC is planned to be a standalone QBUS card - i.e. take a running QBUS system with CPU, memory, etc, and plug in a QSIC for 'disk' storage. Or by 'MCU' were you referring to the -11 CPU? Bridgham has at times wanted to do that, but I'm not enthusiastic - see desert-topping/floor-wax point, plus my point about 'only doing things that aren't easily available' - and QBUS PDP-11 CPUs are readily available. > design the board so that it accepts a processor in "gumstix" or SODIMM > form factor, and expose connections for USB/ethernet.

I don't know if the CPU processes DMA requests when it's stopped. You can't use go ahead and use the bus without asking because the processor is in tight loop issuing DATI's to the console CSR. Noel

Big heap of DEC Flip-Chips modules

by j_hoppe＠t-online.de

Hi, a year ago or so an inventory of several thousand DEC flip-chip modules appeared in the neighbourhood. "Yesss, my precioussss, it came too me !!!" But I couldn't acquire them. At least I help selling them now. The inventory is here: retrocmp.com/flipshipshop It was a 2-months-project: most fun was sorting and counting the modules, then taking the pictures. A webshop solution seemed the best for online presentation. (Very interesting, I never did that before) Functionality of the shop software is good. On the other hand this project appears a bit too commercial now. You even should be able to buy online over Paypal, but I'd prefer personal contact. Joerg

flash (or ide) storage for unibus 11?

by shadoooo＠gmail.com

Hello, I have some unibus machines that always need some way to interface to modern disks. I always dream to make an universal board that could act as disk and/or tape interface to a modern medium (scsi or cf/sd card), but also ram, network, I/O, whatever... It would be very nice to design a system based on fpga + cpu (arm), so you can load linux on it and avoid the hassle of handling file systems for the sd card, management and configuration, etc. The low level part, the access to the bus, address decoding, and all the parts that need real time reactions could be handled by the fpga. The good part is that I could really help to design a system like this. The bad is that it is expensive, specially because you have to use bga components that need to be mounted by smd assembling machines. But: there's always the possibility to choose a commercial development board, and mount it as SOM over a larger board that would include only psu and bus level translators. This way could be cheaper and can be mounted by skilled hands... If there's a number of people that would invest some money on it, to repay tooling and minimum lot costs for the pcb and components, we could definitely work together to make it. Anybody interested?

Not sure I see the purpose? Any of the storage devices (SD card, or thumb drive) can of course be pulled out and plugged into another machine. > From: Andrea > there's always the possibility to choose a commercial development > board, and mount it as SOM over a larger board that would include only > psu and bus level translators. This way could be cheaper That's basically what we're doing for the prototypes, except that our prototype motherboard is wire-wrapped. The mobo (currently) has only i) bus transceivers, ii) level converters from +5V logic to +3.3V (nobody supports +5V in any modern FPGA part, and QBUS transceivers are pretty much only available in +5V - although we'd be happy to be informed otherwise), and iii) a pair of 64-pin DuPont connectors to a FPGA/uC board from ZTEX. (We may add more, e.g. when we get to debugging the indicator panels, we'll probably put the drivers on the prototype motherboard. Etc, etc. That's part of the reason for going with wire-wrap, it's easy to add stuff like that.) It is, alas, not that cheap overall. We think the production models, with all the circuity on a single custom PCB, will be somewhat cheaper. In addition, you can't really stack the ZTEX boards on another board, and meet the QBUS inter-board spacing. Noel

IBM 4341 and 3880 floppy disks

by nf6x＠nf6x.net

I recently acquired a small pile of 8" floppy disks which appear to be for IBM 4341 and 3880 hardware: https://twitter.com/nf6x/status/669240958492372992 They're on my "to be imaged" pile. I don't have any hardware to go with them, and would be happy to trade them away after imaging them. They apparently came from a military surplus commo shelter whose innards were being scrapped out. I don't think that the hardware is still in the shelter owner's hands, and I wouldn't have wanted to acquire it anyway, but I thought it would be fun to try to preserve the contents of the disks he had in there. Based on the label picture linked to above, do any of you IBM fans know whether the contents of these are likely to be interesting to anybody? -- Mark J.

{Catching up, after being on the road all day yesterday... Replies to quite a few people in this, sorry you'll have to read through it to find yours, didn't want to inundate the list with 17 replies.} > From: Jacob Ritort > Are you on keeping bits and/or status for these projects on github or > anywhere else that might encourage participation and contribution? We're going to make it public, but at the moment, it's a bit early for that; for one thing, we are working with hand-wire-wrapped prototypes, front-ending a ZTEX FPGA/uC (micro-controller) board, not a PCB card. And the 'software' (which includes FPGA code, we don't have any code for the uC yet) is in a very primitive state. We'll probably get a couple of controllers done (RK11, RP11, probably RL11, qetc) and then turn it loose for people to add others. > I'd be glad to pitch in if I can. We we get to the stage of turning it into a production PCB, we are definitely going to really encourage help for that step - doing PCB layout, etc, is sort of terra incognita for us both. > Actually, I (and I bet others) would love to see an up to date wiki > entry or somesuch listing folks' retro projects like these Well, we'd need the wiki first! But I hope to have some news on that front soon - I've located an existing one, and am discussing with the person who runs it, using it for material from CCTalk. > From: Henk Gooijen > Tell us more ... and keep us posted Noel. Not much more to say, at the moment. The plan is that it will be a dual QBUS card, with slots for two SD cards, and also one (or more) USB 2.0 connectors; although it will be possible to plug in memory sticks (to the USB), the SD cards will probably offer higher performance. Oh, and one will be able to configure virtual disks on on-board RAM; the contents won't survive a power cycle, but they will be very high performance, useful for swapping disks. We will definitely keep CCTalk posted when there is any news. > We *love* blinkenlights !! Why do you think they are in our plan? :-) We love them too! :-) > if you have a blank front panel this "fills nicely" Well, like the originals, they will be half-panels (i.e. 5-1/4 inches). They will not be electrically compatible with the original DEC indicator panels (we plan on driving them like Guy, with just a clock and data on a couple of wires, not one wire per light - in fact, I'd like to use a common connector and electrical spec with Guy's, so they are compatible); making them electrically compatible would be a _lot_ of work, and I don't see that it would be worth it. However, they will be mechanically compatible with the DEC originals; our plan is that if someone has an original indicator panel PCB (I know at least one person here does), they could mount it with one of our new production bezel/inserts (with the light captions on it), and the whole thing will work. I.e. in the original DEC design, we're just replacing the PCB. > Heck, why not address (all 22) and data too? Although 'classic' RP11/etc panels will probably be available (for purists), we intend to also do 'updated' panels which will drop a lot of lights that make no sense when you don't have a real disk (e.g. the shift registers) and replace them with useful lights that the originals don't have (e.g. full memory address, on the RP11). > From: Paul Koning > For a classic/straightforward programming interface, the Massbus disks > (RP04 and successors) are a good choice. That will take you just over > 500 MB, if you emulate the layout of the RP07. We'll probably do those too, but before that, we're thinking of doing an RP11+, i.e. an RP11 with the cyclinder address extended to 16 bits; i.e without changing the register format _other than using unused bits_ in the cyclinder address register. (Very easy for us to do, of course.) For those with the ability to tweak drivers, that will produce disks with 2^28 blocks, or 2^36 bytes, or 64GB. That's most of a large SD card... :-) > Sure, you can throw in a microcontroller, but interfacing that is > likely to take far more gates than doing the mapping in the device > directly. Alas, we pretty much have to have a uC; it's pretty much mandator to support USB. And once you have one, there's a lot of stuff that's easier to do in a uC, e.g. reading the configuration of the virtual controllers, and configuring the FPGA to match, etc, etc. > From: Rich Alderson > Why bother with the RP11? Because, for FPGA implementation, it's basically an RK11 with a few tweaks --> very easy to do! And with the RP11+ variant, it will support up to 65GB disks.. :-) > From: Mike Ross > Because, blinkenlights! :-) That too! Although there's nothing to stop us doing light panels for controllers that never had them, e.g. RL11's! > From: Johnny Billquist > 22-bit addressing is not possible on the Unibus. True, but my concept is that the eventual UNIBUS version will include ENABLE functionality (i.e. mapping boxes to 4MB memory, one for the CPU, and an 11/70-compatible UNIBUS map for DMA devices), and it could therefore _also_ 'emulate' a MASSBUS RP11, i.e. an RP11 with an additional 'extended memory address' like the identical registers on e.g. the MASSBUS RP04. (And yes, I know no such device ever existed, so unmodified DEC OS's won't support it, but...). > Your native interface have the additional problem that in addition to > requiring people to write their own device driver for any OS usage, it > will be rather difficult to get booting from it, since that require > special support. Right, but since adding another controller on the QSIC will be a trivial configuration option, we assume no machines will have _only_ an RQ11 (our aname for the 'native' interface), but rather an RK11 and RQ11, RL11 and RQ11 etc. Boot off the first, only use the second once the OS is running. > RK11 and RP11, while fairly simple, are also very small devices. Well, there's always the RP11+! :-) And the 'RPV21' (again, I know this never existed) will, like the RLV21, have native 22-bit addressing. > Massbus is a bit more useful, as it at least gives some larger devices, > but you need to implement each device. It's all 'software' (in the FPGA and the uC); so if we (in the community sense) upgrade the 'software' to support more controllers/disks, all boards could be upgraded to support them. Let's get the RK11 and RP11 working to start with, and then we'll figure out where to go from there. > However, if you want to write a device driver for a device you want to > boot from, you need to modify SAV as well, which is *not* documented, > and very non-trivial. Not recommended for the faint of heart. Which is why it's probably easier to just _also_ configure a standard RK11/RP11 whatever, and boot off that. (It's all 'software'! With the right FPGA load, you could have 127 RK11 controllers! :-) Noel

Emulation

by wulfman＠wulfman.com

I know most of you have or are searching for the real thing. But for those of you that still don't have what your looking for, the arcade emulator MAME has now included most old computers in their emulation program. I have seen everything from apple computers to vax systems, while searching for game roms. Most are still non functioning as of this version but they are working on making them work. one that does work is a pdp1. http://mamedev.org/ emulator http://www.mameui.info/ windows gui front end http://retroroms.net most current list of roms in the download section, free reg required I have been collecting roms for years for repair of my huge collection of game board but this is the first time i have seen the retro computers in the rom sets. maybe if they are in need of a rom dump for some obscure computer one of you have you can contribute to the scene by dumping and sending the rom they are looking for.

While > fairly straight forward, it do expose you to a rather low level > interface, where you need to do a lot of calculations all the time. All those old disk controllers expose the disk geometry. I've looked at it for the specific case of the RK11 and it doesn't look too bad. If it does turn into a problem, then we'll have a microcontroller on the board too and I'll punt the calculations to it rather than doing them in the FPGA. And my third option is to just do the trivial mapping of the sector/surface/cylinder numbers to LBA and waste space on the flash device. It's not we're so short of storage space in emulating any number of RK, RP, or RM class disk packs.

Two things. 1) There is not such things as "TOPS". The 2 operating systems for the PDP-10 provided by DEC are Tops-10 and TOPS-20. The only thing they have in common is the first 4 letters (modulo case) of the names. They share exactly no code in the monitor ("kernel"), and do not even have the same origins. Tops-10 started as the monitor on the PDP-6, in 1964, and was in continuous development until 1988 (and in maintenance until 1993+), while TOPS-20 began life as the TENEX operating system from BBN c. 1969, licensed for the new KL-10 processor while that was under development. TOPS-20 v1 appeared in 1975. BBN developed a run time package for TENEX called PA1050 which handled a subset of the Tops-10 system calls by merging into user-mode programs and intercepting them; DEC carried on the same mechanism to allow Tops-10 compilers and other utilities to run on the new OS while native versions were developed. 2) Having stated all that, Tops-10 does not allow mixing tapes and disks on a channel, but it does allow mixing disk drive types. TOPS-20 has always allowed mixing tapes and disks on a channel.

I have the little code I've written so far in a private git server but not on github. Eventually the plan is to do something like that but we're pretty early in the process. Certainly nothing is running yet. Even though I've set up a git server, I still have to learn how to actually use git. However, once we get a prototype doing something interesting, we were talking about looking around for people interested in helping out. We'll do a couple disk controllers but if someone wants to add others, great. Especially if someone wants to add MSCP. We're happy to skip that one ourselves. But the real thing we'll want help with is circuit board design and manufacturing. We can do easy things but I'd really like to use BGA parts for the FPGA and memory chips so if someone has a handle on that, we'd like to talk. A I said, our plan was to get a prototype working before going in search of this kind of assistance. We're using an FPGA module from ZTEX right now to sidestep the issue. Is there a wiki out there that holds this kind of information? It seems like a great idea and I'll put some information together on our project if there is. Or maybe, now that news is spreading that we're doing this, it's time to write up a web page describing what we're up to. -Dave

Front Panels - Production

by rodsmallwood52＠btinternet.com

Hi Guys I'm due at the screen printers on Wednesday. I've now incorporated what I have gleaned from the loan panel into the drawing set. For 8/e panels we now have the following layers to be printed. _On the front: _ First will be a translucent matte base coat to give a satin finish. It looks black because of the black layer on the back of the panel. Then either the Terracotta or the Amber and finally white. At this point the panel is neither a Type A or Type B . White only detail in the selector switch area and the dividers between lamp groups can then be added to give the panel its identity. There are two small screen separations to allow this to be done. _On the back:_ The 8/e back side (/f and /m differ I'll explain that later) has a heavy black layer with clear round areas for the lamps / LEDS to shine through. In just the lamp area there's another translucent matte layer. This and the one on the front act to diffuse the light coming from the lamps/LEDS. Thats seven layers in total and they have to be dried after each layer goes on. Each one needs a silk screen and when being printed registration is critical. Its a skilled job and not one I would care to have to do. More news when I have it. Rod (Panelman) Smallwood

A Selectric printer...

by tmfdmike＠gmail.com

I have an I/O Selectric device which is badged as, and was originally, an IBM 2970 Reservation Terminal. For better or worse, it was one of those bought up in the late 1970s by a company called 'Western I/O", based out of Scottsdale Arizona. They converted them for home use. One version used a Motorola 6800 to make a nifty-sounding terminal with selectable baud rates etc. I appear to have the 'other' version; a cheap and nasty printer-only conversion with some form of parallel port. Anybody else got one? Docs about them? Parts? Schematics? I'd like to get hold of one of the 'proper' terminal conversion versions... Must be some squirreled away in garages! Alternatively, any doc on the original 2970? There's an incredible dearth of information about what we're once very common devices...

Any AS/400 hackers? Linux question

by tmfdmike＠gmail.com

Might not really be old enough for this audience but it's an obscure enough question! I have an AS/400 9406-S20 - mid 1990s vintage. These things could have what IBM called an 'Integrated Netfinity Server' - basically an Intel PC on a board, using space on AS/400 disk etc. Two such boards work in this machine: the 2852 (Pentium Pro) and 2865 (Pentium II). Both ran NT, and that's well-documented in a Redbook. Both could also allegedly run OS/2 and Netware. it wasn't officially supported I know, but did anyone ever succeed in shoehorning Linux onto either of these boards? If so, how? Official support only came with the next iteration of hardware (which my system can't use), and relied on the 'PC on a board' having USB ports, and involved the use of a USB floppy drive (!) to complete the Linux install process! (I'm at V5R2 btw, and have had NT running on this board) Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother.

ICL Quattro

by supervinx＠libero.it

Hi! I found an ICL Quattro desktop computer. It looks in good shape, I had to repair only the PSU. Powering it up, I see disk activity, but I haven't his (proprietary?) monitor. On the back, I see a bunch of serial ports (DCE? DTE?) and a DB15 connector, I guess for monitor/kbd attachment. I tried to connect a terminal to the serial ports, with null modem and straight settings, but I had no answers. Do someone have some infos about the proprietary monitor/kbd port? Can it be run without the original monitor/kbd system? Or should I think about it as a... doorstopper? :D Thanks! -- Vincenzo (aka Supervinx) --==ooOoo==-- My computer collection: http://www.supervinx.com/OnlineMuseum --==ooOoo==-- You can reach me at: www.supervinx.com www.facebook.com/supervinx http://www.youtube.com/user/supervinx http://www.myspace.com/supervinx

Looking for an IBM manual PDF

by captainkirk359＠gmail.com

Hello all, I'm looking for a PDF copy of IBM manual GC26-3792-8. The System Generation manual for MVS 3.8; the only PDF I found of GC26-3792 is of the -1 version, which is not particularly helpful. I found a DjVu of the manual (via this site: <http://tk3.comlu.com/mvs380/Vintage_Manuals.html>) namely here: <www.classiccmp.org/softlib/manuals/GC26-3792-8/GC26-3792-8.djvu> Unfortunately, downloading the DjVu file does nothing (SumatraPDF on Windows can't render any of the pages, and Evince on Debian 8.2.0 just ignores the file); the Java applet to view it works... except it doesn't play nice with my accessibility needs. So, anyone have a PDF of that manual? Cheers, Christian

Deciphering PDP-11/05 ZQKC (Instruction Exerciser) MAINDEC failures...

by derschjo＠gmail.com

Hi all - As noted in a mail last week, I now have my PDP-11/05 running with working core (8KW). I had some time last night to try loading in some "real" software, and I started with the PDP-11 paper-tape BASIC, which I've successfully loaded into memory (in theory). At this point, it became clear that there's still an issue or two to iron out in the CPU; BASIC behaves extremely erratically, spewing random error messages, listing garbage, and corrupting itself and crashing pretty quickly. I'd run the memory exerciser MAINDECs previously (and I ran them again for good measure) and there are no obvious issues with the memory. The system exerciser diagnostic (ZQKB) passes, but the "11 family instruction exerciser" (ZQKC) fails after a minute or so at PC=016014. I have the listing for the diagnostic (though I'm not precisely sure whether it's exactly the same revision) from here: http://bitsavers.trailing-edge.com/pdf/dec/pdp11/xxdp/diag_listings/MAINDEC… The doc is pretty grainy but the code at 016012 doesn't actually seem to match what I've got in memory (I disabled relocation in the test just to be sure things didn't get moved around) and there's no failure check at that particular point in memory either. I've tried the paper-tape images from Bitsavers as well as the ones on the XXDP RL02 images floating around out there and they all yield the same results; I suppose it's possible the CPU is failing in such a way as to make the test reporting incorrect but it seems more likely that (a) I have an outdated listing or (b) I'm misinterpreting the results somehow. Anyone have any experience with this particular diagnostic? Thanks, Josh

Front Panel Orders - Special Update

by rodsmallwood52＠btinternet.com

Hi Guys Well the original panel arrived yesterday and revealed one or two interesting features. It was from an 8/m but as the underlying programmers console (apart from the change from bulb to LED) is the same for all of versions I am making. Its a good example What it reveals was that they silk screened the panel first then routed or milled out the openings using the markings as a guide. This is the source of much complained of chipping and peeling. This means that they did not have to be too fussy with the placement of the silk screening in relation to the edges of the blank. Any small offset would be hidden by the bezel anyway. in addition there is plenty of tolerance on the key lock - there's provision to adjust its position on the mounting. The hole for the select switch is drilled over size (0.38" for a 0.25" shaft) so more room to move things about In the spirit of "measure twice and cut once" would all those with orders please do the following. Take off the selector switch knob. Remove the bezel and take the old front panel out. Measure from the bottom edge of the panel to the bottom of the row of switch openings. Then from the left hand side to the first switch opening. Finally from the right hand side to the last switch opening. Please send the three measurements with the type of system its off plus any part numbers on the back of the panel to me. Regards Rod

Todays Topic from Panelman

by rodsmallwood52＠btinternet.com

Hi Guys I think we are all only too well aware of the difficulty of getting parts for our old systems. This the more so for items that can been seen. Having got at least a half reasonable replacement front panel process my thoughts turned to toggle switches. In the case of PDP-11 this is already being addressed by another list member. So to PDP-8's. There's two parts to a PDP-8 toggle. The slide switch and the lever. The leaver is injection molded in a two part mold. The join line can clearly be seen. Clearly a mold is required to produce one or more at a time. These used to be very expensive but with modern CNC machines it might be worth finding out. In addition we now have 3D printing available To aid this have I have produced a drawing of the switch lever with views from three angles. From here it should be possible to: 1. Convert to 3D for 3D printing tests 2. Produce a drawing of the two part mold tool. Extruded PVC I'm familiar with having worked in the cable industry as a student. ABS which is what I think the leaver may be made of may be different (hot to cold shrinkage for example) Comments from list members with experience in the above areas would be of interest to us all. Now to the slide switches themselves. They are mounted by the screw hole lugs having been slid into a groove in two aluminum bars which in turn are attached to the PCB by pillars and screws. There are six connection pins on the bottom of each switch that go into holes in the PCB. (not all used) Switch replacement would be easy and a complete switch and lever sub module not too difficult. I hear a voice >from the distant past saying 'Micro switches' Thats all for to-day Rod

So far it looks like I need to add a band of gray matte base to the front and a band of similar over the light ports on on the back. Looks like I have a new product. It's called an "Invisipanel" Its a clear plexiglas blank I use for checking alignments. Because its so clear I cant find it!!!! Rod

Testing bus transceivers

by jnc＠mercury.lcs.mit.edu

> From: Guy Sotomayor > A number of data books have circuits that were used to measure the > parameters .. so you might want to look at some of them Thanks for the tip! Alas, I don't know of any data books with circuits like that - any pointers? (And it's only the leakage current I need to check; the other 3 key DC parameters I have already managed to check.) > From: Mark J. Blair > Do you have any sort of precision, regulated, adjustable lab bench > power supply that you could use to vary input voltage? Well, I have some Lambdas, but I'm not sure they are 'precision' (any more - the pots are kind of dirty/flaky, so they jump when you turn them). > If not, using a potentiometer as you mentioned would also work. Yeah, that's what I did - running a 500 ohm pot from ground to +5V provided a nice input, and I was able to verify the 'maximum 0 input voltage' and the 'mininum 1 input voltage' quite easily. I also realized that in a system with 'normal' single QBUS box with termination, one has a 330 ohm pull-up in the CPU's termination, and 180 ohm pull-up in the BDV11 terminator, which adds up to 42 mA into the transceiver when pulling to low voltage; if one adds another 180 ohm pull-up, that adds another 28 mA, getting me to the required 70 mA for the 'maximum 0 output voltage' check. Since the QBUS specs allow another termination, if you have a second box, that's probably why they spec it at 70 mA, actually. > Also, how many of these did you buy? Umm, like 400? :-) (Dave Bridgham and I are winding up to produce a QBUS card which uses SD memory cards along with an FPGA and micro-controller to emulate a range of DEC disk systems - RK11, RP11, etc - and we wanted to assure a goodly supply of our selected transceiver chip before we spin out a PC board.) > If it's something like a dozen, manual testing will be practical. If > it's something like a hundred, then automating the testing might be a > good idea, and a fun project all by itself if that sort of thing > interests you. Well, not really, to be honest (I'm not an analog person), plus to which I have a zillion other projects (e.g. a bunch of UNIBUS machines to refurbish, plus other non-computer things) which are backlogged, the last thing I need is another one! ;-) Also, you might be able to automate the _testing_, but one still has to plug the chips in and out, which is a certain amount of work, so it's not like automated testing would allow me to trivially check really large numbers of chips. Which is why I've adopted the 'test randomly selected units for meeting specs' approach (remember, I'm just trying to make sure these aren't counterfeits), and for that, manual testing works fine.

PDP 8a transformer capacitor replacement?

by thebri＠gmail.com

Having read all sorts of bad things about these older oil filled capacitors, I decided to replace the one on my 8a. I got what I think is a replacement - 6 microF, 660VAC, 50/60Hz, "NO PCB's" - but it is physically about 1/3 the size as the original. Did the tech for these get that much better? What purpose does this serve? It's hanging off the transformer. I see lots of links about motor start capacitors, but nothing relating to transformers. http://www.mouser.com/ProductDetail/Cornell-Dubilier/SFA66S6K288B-F Thanks, b

Nextstep: Visions in black

by simski＠dds.nl

While copying some data from a bunch of Next HD's, i stumbled upon a snd file containing a song written for Steve Jobs, accompanied by guitar and handclaps from several people. Is this a known song? I was unable to find a better version on the web than the 8012hz sample I have here. -- Met vriendelijke Groet, Simon Claessen drukknop.nl

Testing bus transceivers

by jnc＠mercury.lcs.mit.edu

So, I have bought a number of DS8641 bus transceivers from a source in China, and cognizant of the claims that there are a lot of counterfeits coming from China, how can I test them to make sure the meet specs? I have a QBUS test board which I have constructed (it's basically just a single read/write register), so I can verify their _basic_ functionality; but the UNIBUS/QBUS specs give a number of analog qualifications, and it's those I'd like to check. Some of them I can figure out how to test, although a couple of them would seem to need special test rigs, e.g. input high threshold of 2.5V and low threshold of 1.4V, but I _think_ I can work out how to test those - a board with a pot on it, so I can vary the input voltage, and see where the output switches. (I'm not necessarily going to test every last chip, but I'd like to do random samples.) However, there are others of which I'm not at all clear how to test, e.g. output high leakage current of 25 uA. How would I test that? (And replies of the form 'use such and such an approach' probably aren't detailed enough for me - my analog-fu is pretty weak - so details would be most greatly appreciated! ;-) Noel

To-days Panelman Poser

by rodsmallwood52＠btinternet.com

Hi Guys! I am the happy owner of a DEC 3000 in other words an Alpha. It is fully working and boots VMS and goes into DEC windows just as it should. Its running a high res 23" colour monitor in RGB As you all are aware I spend my time recreating PDP front panels. (Hopefully the example panel will arrive to-day and I can release the current batch to screening. ) Anyway I thought it would be nice to at least get some pictures up on the Alpha and maybe do a little panel design on it. If you are asking why would I want to do that. Then I might suggest you may not be on the right list. So there you have it; picture display (gif, tif and so on) and a bit of cad on my Alpha (mono is fine.) What do I need and where do I get it? Rod (Panelman) Smallwood

Oh boy, copyright discussion.

by jason＠textfiles.com

I'm very disappointed this only flares up once every month or two, is there any chance we could make it once a week? The reality of perpetual and automatic copyright that extends past the death of all listed creators means that there are a lot of pieces of items that have no advocate, financial interest, or caretaker either legal or otherwise. It is a ridiculous situation. The arguments where the only two options are this "Zardoz" environment or water break down of the entire copyright machine, is old and bores me. The reality as I have experienced it is that there are a few white-hot pinpricks of interest and legitimacy by a vanishingly small amount of companies, and then there is a vast Black Sea of unwanted, uninteresting, forgotten items. This works for software as well as everything else. If there is a choice between oblivion and the dumpster, and sending it to the Internet Archive, I will ensure that our doors are open. That's all I can offer to everyone here. You can reach me at this address or by calling the archive directly if you don't want to deal with me. If all you have to offer is another 7 paragraphs of bloviating, that's why they make the mute button.

Shipping help near Fresno, CA

by derschjo＠gmail.com

I've been trying to get a PDP-8/m out of Fresno, CA for a few months now; the person I'm getting it from is alternately unwilling and unable to prep the machine for transport (the latest excuse is that he can't find a suitable pallet). This is a single full-height rack, probably about 500lbs -- is there anyone on the list nearby (Fresno, CA) who might be able to prep the machine for transport (e.g. strap it to a pallet, maybe put some padding over the front panel to reduce the possibility of damage)? Then I can get a shipper to drop by and pick it up. I'll gladly compensate you for your time/effort. Thanks! Josh

> From: js > if they still wanted income from it, it'd still be for sale. If it's > not for sale, and I can find it, then I'll use it and be sure not to > profit from it. This ties in with something called 'fair use' under US IP law, see here: https://en.wikipedia.org/wiki/Fair_use for more. Basically, 'fair use' permits _limited_ use of copyrighted material without acquiring permission from the IP owners; there is a 4-part test which is applied to determine whether a non-licensed use meets 'fair use'. The parts are: "- the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes; - the nature of the copyrighted work; - the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and - the effect of the use upon the potential market for or value of the copyrighted work." ii) doesn't really apply here, and of course one would score poorly on iii), but since a) one's not making any money from it, that would score highly under i), and b) there is zero effect on the market, since the thing isn't even for sale, so scoring highly under iv). So use for vintage computer hobby puposes might well be (in the US at least) 'fair use', and not in fact infringing, even without a license. In other countries, it will depend on their copyright laws; e.g. in Israel and Poland, the same might be true. Noel

It was useful to "image" DOS computers with it. I don't think these were straight through cables and you needed the laplink software to be running on both sides. I see the cables on ebay, I picked up a set a few years ago to move contents of similar MS DOS system. Serial is much slower than parallel obviously. If you must use Linux, you may find something that emulates dos, or you can rewrite the receiving - end Linux equivalent of laplink if it has not already been done.

VT100 - FUN

by rodsmallwood52＠btinternet.com

Hi Guys Going back to the days when I worked in marketing in DEC Park (Then new ,now demolished) I had a VT100 on my desk. We all did, email, word processing graphics and so on. Now there was one interesting but little known VT100 feature. On the back it had two BNC connectors. They were for video in and out. You could sync the VT100 to a feed of mono video and the overlaid picture would appear on the screen and at the video out connector. The only secret was you had to set it for 50Hz . One of my hobbies then (still is now) was Amateur TV (a branch of ham radio.) I had built my own TV camera (we all did). I'd made it small and light to go portable with. So I took it to the office early one morning hid it in my gray wall (VMS manuals) and got it going. I pointed it down the (very) open plan office and went off to my first meeting. It worked, when I got back there was a gaggle of very bemused people looking at the screen. Rod Smallwood

x86/DOS system backup via rs232?

by jules.richardson99＠gmail.com

As per subject line, does anyone know of any util that will back up an x86 PC running some variant of DOS (MS, Compaq etc.) via rs232 to a remote system? (Linux preferable on the remote, but other options exist) I'm not finding anything via Google, but it seems like the sort of thing that some of the folks here may have done for their systems in the past. I'm thinking something that will do a sector-by-sector transfer from a given partition (maybe only in-use sectors, implying some minor intelligence on the remote end to covert into a raw image, but "send everything" mentality is better than nothing) - extra points for retrying bad sectors. cheers Jules

Compulog Two Intercole Systems PAC 16

by mattislind＠gmail.com

Anyone know more about this old 16 bit computer / controller? http://i.imgur.com/utUfMQe.jpg According to the current owner it is based on a 16 bit machine made by Computer Automation. It has core memory and is programmed in assembler and Fortran. It is from the late seventies. I found very little while searching the net. Intercole systems seems to still be in operation. PAC 16 could relate to Varisystems corp which I found in this document: ftp://bitsavers.informatik.uni-stuttgart.de/topic/minicomputer/ComputerDesign_Apr71.pdf In any case the Varisystems PAC 16 seems to be a rather simple 16 bit machine. But is this the same? And is Varisystems related with Computer Automation somehow? Any information is appreciated. Is it worth rescuing it? Any software to look for? The current owner has loads of 8 inch floppies.

All my tests were done under Ersatz-11. I just tried to boot V04.00 of RT-11 on a PDP-11/05 using an RK05 device (RK:) under the RT11SJ.SYS monitor. First I set the memory to 32 KB (16KW) and it worked quite well. Then I tried with 16 KB (8KW) and while it did boot, during the boot process of V04.00 of RT-11, I did see the error message: Insufficient Memory On the other hand, I was able to perform a DIR and a few other tests which did work. I then attempted to confirm with V2 and 16 KB of memory and that also worked with the RK05 device. Obviously, it is not possible to do very much with just 16 KB (8KW) of memory. As for support for the TU58 device (DD:), I also attempted that and came up empty. using V3B of RT-11. The V3B distribution which I have does not seem to support the TU58 since RT-11 crashes when I attempt to use the TU58 device. There may be some bad code in RT-11 when the TU58 is used with a PDP-11/05. I just don't have the resources in the time that is available to find out. Josh, you don't mention if you have a disk drive of any kind on the PDP-11/05, It would help if you could describe all of the available hardware. If the TU58 is the only "disk drive" available, then I am not sure what to suggest in order to get RT-11 to run in any case. Jerome Fine

Software for small-memory PDP-11s?

by derschjo＠gmail.com

Hey all -- Now that I have my PDP-11/05 running nicely, I'm curious what others are running on small systems like this -- until this point I've only played with larger (i.e. at least 28KW memory) systems. I have only 8KW of memory (with no viable options for expansion) and there's not much out there that I've found. There's paper-tape BASIC (which is always fun) and FOCAL, and PTS-11 (http://iamvirtual.ca/PDP-11/PTS-11/PTS-11.htm) which is pretty cool if a bit cumbersome. Any other suggestions? I'm also curious if any version of RT-11 that supports the TU58 could be made to run on this system -- I have two SLUs in the system so in theory I can boot from an emulated TU58. However RT-11 4.0's SYSGEN manuals suggest that 12KW is the minimum supported (and experimentation bears this out) and I can't find much in the way of manuals for RT-11 V3B -- which I believe is the earliest version with TU58 support.

In Memoriam: Gene Amdahl 1922-2015

by christian_liendo＠yahoo.com

http://m.cacm.acm.org/news/194192-in-memoriam-gene-amdahl-1922-2015/fulltext Gene Amdahl, who formulated Amdahl's Law and worked with IBM and others on developments related to mainframe computing, died recently from complications of pneumonia. American computer architect and high-tech entrepreneur Gene Myron Amdahl died Tuesday at the age of 92. Amdahl?s wife Marian said he had suffered from Alzheimer?s disease for about five years, before succumbing to pneumonia. "We are thankful for his kind spirit and brilliant mind. He was a devout Christian and a loving father and husband. I was blessed with having him as my husband and my best friend. I praise God for His faithfulness to us for more than 69 years." Born to immigrant parents in South Dakota, Amdahl served in the U.S. Navy during World War II. He completed a bachelor?s degree in engineering physics at South Dakota State University in 1948 and went on to study theoretical physics at the University of Wisconsin-Madison, where he received his doctorate in 1952. Amdahl joined IBM in 1952, where he worked on the IBM 704, the IBM 709, and then the Stretch project, the basis for the IBM 7030. He left IBM in 1955 but returned in 1960 and became chief architect of the System/360 mainframe computer. Amdahl was named an IBM Fellow in 1965, as well as head of the IBM Advanced Computing Systems Laboratory in Menlo Park, CA. He left IBM again in 1970 and set up Amdahl Corporation, which specialized in IBM mainframe-compatible computer products, with the help of Fujitsu. The company manufactured "plug-compatible" mainframes, starting in 1975 with the Amdahl 470V/6, a less-expensive, more-reliable, faster alternative to IBM?s System 370/168. Amdahl's software team developed Virtual Machine/Performance Enhancement (VM/PE) software to optimize the performance of IBM's Multiple Virtual Storage (MVS) operating system when running under IBM's VM operating system. Within four years, the corporation had sold more than $1 billion of V6 and V7 mainframes and had more than 6,000 employees worldwide. At ACM's Spring Joint Computer Conference in 1967, Amdahl participated in a discussion on future architectural trends, arguing for performance limitations in any special feature or mode introduced to new machines. This resulted in what came to be known as Amdahl?s Law regarding sequential vs. parallel processing. Amdahl left his company in 1979 to set up Trilogy Systems, an organization aimed at designing an integrated chip for even cheaper mainframes. When the chip development failed within months of the company's $60-million public offering, Trilogy focused on developing its VLSI technology, which also did not do well. In 1985 Trilogy was merged into microcomputer manufacturer Elxsi (now Tata Elxsi), but poor results there had Amdahl leaving in 1989 for a company he founded in 1987 to produce mid-sized mainframes, Andor International, which had been driven into bankruptcy by production problems and strong competition by 1995. In 1996 Amdahl co-founded Commercial Data Servers, again developing mainframe-like machines but this time with new super-cooled processor designs and aimed at physically smaller systems. The company, now known as Xbridge Systems, develops software to scan mainframe datasets and database tables for sensitive information such as credit card numbers, government identification numbers, and medical diagnosis information. In November 2004, Amdahl was appointed to the board of advisors of Massively Parallel Technologies, a Scottsdale, AZ, software engineering firm. Amdahl was a member of the National Academy of Engineering and the recipient of honorary doctorates from four institutions. He also was the recipient of the IEEE?s Harry H. Goode Memorial Award, a Fellow of the Computer History Museum, and recipient of the ACM Special Interest Group on Design Automation (SIGDA) Pioneering Achievement Award. Said David Patterson, a professor of computer sciences at the University of California, Berkeley, and a computer pioneer in his own right, "The IBM System/360 was one of the greatest computer architectures of all time, being both a tremendous technical success and business success. It invented a computer family, which we would call binary compatibility today. When he left to form his own company, his mainframes were binary compatible with the System/360." Patterson noted the brief paper Amdahl submitted to ACM?s Spring Joint Computer Conference "basically offering a critique to enthusiasts about the parallel supercomputers of the era." He cited the beginning of that paper as laying out the arguments for what became Amdahl's Law:

In fact, it would be interesting to know where all the interesting collections in Italy are, as I do visit the country with some regularity. Annoyingly, I noticed just now that there is one near Siracusa, and I might have been able to visit that this past summer. Regards Rob

DECtape reliability?

by tomjmoss＠googlemail.com

I've had very mixed (about 50/50) success with 9-track, but after reading a bit about DECtape it looks like they should still be holding up nicely. Anyone care to share their experiences?

8 inch media

by sales＠elecplus.com

Several people were asking for 8" floppy diskettes. I found some new at the recycle center. Maxell FD1-128 single sided, single or double density, soft-sectored. Total of 17 disks. Asking $2 each plus shipping. Cindy --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
