> >Well, I installed some random jumpers and it got me to a console prompt! > Tony's not going to be pleased :-) I wouldn't recommend it either. If it were me, by the time time I got to the next problem, I would have forgetten what jumpers I put where that might have caused it. Ideally, I would suggest finding out what the jumpers do, figure out how they might affect the problem in hand and what other problems they might cause. It is possible that some of them should actually be there but were removed by a previous owner following a similar approach to problem solving :-) Consider removing the added jumpers one by one to determine which ones provide some improvement, leave the rest out and then stick a note to yourself about them inside the case. > >KA41-A V1.4 > >F_..E...D...C...B?..A...9...8...7...6...5...4_..3_..2_..1?.. > > > ?

In a combination of vague recall and guessing, I think that E and D are probably due to the lack of battery and indicate problems with the real time clock and non-volatile storage. C refers to the serial interfaces and I think you get an error because one can't be tested as you are using it as a console. B refers to the memory. This is probably the only error of consequence. 7 and 6 refer to the SCSI buses and I think you get a fatal error if they are not terminated and a non-fatal error if there are no devices visible on the bus. 1 refers to the network interface and you get a fatal error if there is no network plugged in to the selected connector. (F would refer to the monochrome frame buffer if this was a VAXStation and 4 would similarly refer to an optional colour graphics card.) Regards, Peter Coghlan.

Looking for Spectrum QL disk interface and more

by alexandre.tabajara＠gmail.com

Hi guys! I'm in love with my Spectrum QL, but it sucks without a floppy interface. Maybe someone has a spare for a cheap, or wish to xchange for any brazilian made hardware? :o) I'm also looking for microdrive cartridges, an original manual (so beautiful...) and connectors or cable + connectors for the serial and controllers. Thanks Alexandre Souza

Unfortunately, the batterys tend to leak when left for long periods, possibly moreso when exposed to temperature cycling. The electrolyte seems to seems to wick along the connecting wires and attack the board near where it plugs in. I vaguely recall having a 3100 where the leaking battery attacked a memory option board and it used to endlessly cycle around test B, which seemed a bit strange. I would have expected the test to have failed and terminated not get stuck in a loop. Regards, Peter Coghlan.

Help identify mystery keyboard?

by akb+lists.cctalk＠mirror.to

I have a keyboard and don't know what machine it goes to; can anyone help? Pics are at: http://www.flickr.com/photos/61575639 at N06/sets/72157637832745633/ I did not see any branding on it. It has a standard 4 position modular jack on the cord (not a DEC MMJ). It has F1 thru F18 keys at top, S1 thru S6 across the bottom framing the spacebar, and a bunch of less-common special keys like "setup" and "erase". There are three stickers on the bottom, one is an inspection sticker, another says 65-2876-51, and the third says FT10. --thanks for any clues! --andrew

Apple ][ DOS source code is released! (John Ball)

by bdamer＠digitalspace.com

Folks if you want to email me directly I could put you in touch with ohers trying to assemble the Apple ][ DOS source and run it in emluation. Seems like if the PROM emulation is somehow solved we could have this thing up and running. Hey now you can soup up the DOS, add cool new commands (Nutso for those in the know) and create the DOS that could have been if the ][ had rolled forward into the 21st Century and not been [] closed down! I have a sleeve of 16 bit 6502s that was part of project Brooklyn which might have been that super Apple ][. Anyway Apple ][ forever, anyone up to making an Apple II connect to the Internet and serve up its own web page? It was done with a Xerox Star years ago. PS for all you computer history buffs see all the new stories at the DigiBarn at: http://www.digibarn.com including our published assembly code for the 8008 based 1972-73 "Sac State" machine, possibly the first complete microcomputer system (well before Homebrew). bruce

Unix/Solaris Adobe FrameMaker 8?

by other＠oryx.cc

I hope this is OK to post here. I am looking to purchase a copy of Adobe FrameMaker 8. Straight from Adobe, FrameMaker had always been a pretty pricy item, but I had always managed to acquire a legal copy, sometimes years old, after the fact through eBay, etc. And through that method, I own legal copies of 5.x, 6.x and 7.x for Unix and Mac. I had hoped to somehow purchase a copy of version 8 via a similar method, but several years have passed by, and I have never seen a copy of version 8 for sale. After version 8, FrameMaker was significantly changed and released for dos/windows only. I believe that the current version is 10.x. Also, in case it isn't obvious, this is for myself at home only.

Alphaserver 1000 diagnosis?

Does anyone have any idea what's wrong here or is there some kind of >XXDP-like thing I can run that will better test the machine? > I have three Alphaserver 1000A machines all of which have problems. The bcache failed on all the CPUs - there is a jumper on the CPU card to disable it and run with reduced performance (one of the SRM memory diagnostics then fails spectacularly as it divides something by the size of the cache...) On of the CPUs failed entirely. One of the machines used to randomly halt and progressed to randomly powering itself off, possibly due to it thinking a fan is faulty when it is not. On the rare occasions when I've had one working, I found that the correct positioning of the CPU in it's slot can be very critical. I've also had problems with memory failure and found (by doing lots of swapping) that the SRM can report the wrong memory slot as being the one with the problem. The power supply sits there getting hot and consuming lots of power when the front panel power switch is off making it necessary to disconnect it from the mains when not in use. I've had so much grief with mine I've lost interest in trying to fix them. Opinions of the 1000A do not seem to be very high. I think the main difference between it and the 1000 is that the 1000 has more (E)ISA slots and the 1000A has more PCI slots. I don't know if they suffer from similar reliability problems.

transfering files to Unix version 6

by cubexyz＠gmail.com

Hi folks, In my quest to find earlier versions of APL\11 I have come across something called yale-apl, which is most likely from the Unix version 6 era. I can run Unix v6 under simh but I am at a loss on how to transfer binary or even text files into it. I have been able to transfer files from a Unix v7 without difficulty but v6 seems to be quite different. There is no tar utility in v6. Does anyone have any ideas?

PDP-11/44 Power Issues

by b4＠gewt.net

Hello all, I have a PDP-11/44 I want to get the basic tests done before I go further as I have work ahead of me. Backstory: all the cables in the rear were cut. (No big deal, I can rig up a TU58, console, power, and other cables easily). I got the mains cable connected and my Kill-A-Watt shows 13W with the 11/44 "on". This is far as I have managed to get. I do occasionally hear a clicking from the PSU...it's sporadic, unpredictable, current draw does not increase, no smoke, and no visible arcing. It confuses me. I then decided to try the "jumper pins 1 and 3 or 2 and 3 or 1 and 2" to see what would happen. The result? Nothing! I then decided to measure the voltages using pin 3 as the reference. 1 (power request) and 3: -0.01VDC, 2 (power inhibit/emergency shutdown) and 3: 2VDC, 1VAC. This strikes me as...bizarre. Should I have AC there or is my multimeter/my my multimeter skills at fault? I proceeded to follow this logic: "Hmmm. Emergency Shutdown is 2V...that could mean the emergency shutdown state is set. I notice there's an "airflow sensor" board in the PSU. Let's remove it in case it failed somehow." No change there. Any further ideas? The clicking confuses me...it's fairly quiet...something I'd expect from something arcing internally and not a relay. The patterm in't "click-click-click-click" like a relay toggling...it's more random and sporadic with no reproducable cause. It seems to come from the lefthand side (with the power cord on the left). Does anyone have the pinouts for the console cable? I'll need to make one of those up. Same with a cable for a DEUNA. -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

Boxes of Fanfold Paper

by jhfinedp3k＠compsys.to

I mentioned this over a year ago. I have between 6 and 12 boxes of fan fold paper which I will never use. They all have sprocket holes, of course. They are three sizes ranging from 8.5" x 11", 9.5" x 11" and 11" x 14". The 9.5" x 11" has tear off for the sprocket holes becoming 8.5" x 11". I will be sending the paper to the blue box in about 2 weeks, Local pickup in Toronto since this stuff is far too heavy to ship. I also have a number of sets of DOCs for RT-11 which I will discard within about a year. These range from incomplete sets for early versions (probably V3 and V4) to complete sets for early V05.0n DOCs. Since there are PDF files for the most recent V05.06 and V05.07 DOC sets for RT-11, it does not seem important to scan these, but maybe there is some interest. If so, please advise. Jerome Fine

Intel PC Bubble Card Software?

by me＠GarrettMeiers.com

Hi, We just got a couple of these Intel PC Bubble Cards in today, and they didn't have any software with them. Does anyone have the software for these? Or know where I might find a copy? Both of the two cards are pre-production versions. I am not 100% sure of the model #'s. One says Intel "MD-054", and the other says "MD # 25-54", SN#'s 180 and 191 respectively. https://www.facebook.com/media/set/?set=a.246762432147849.1073741851.237349… I also received this in as well, and can't find any information about it. The removable cassette is really heavy. Thinking maybe Bubble Memory? Any help identifying it would be great! https://www.dropbox.com/sh/rpsvjq55h7hlqog/ECmMraCxs3 Thanks, Garrett Meiers Founder, BitHistory.org & President, ConsulNIX, LLC www.BitHistory.org www.linkedin.com/in/theunixguy

Laserjet4 - display ghosting?

by jules.richardson99＠gmail.com

My LJ4 sometimes repeats the last character on the control panel's VF display - e.g. just now when I turned it on it said "warming upp". The repeated letter (and sometimes it's repeated just once, other times more than once) always seems to be fainter than the regular letters. Has anyone ever seen this fault before? It's no big problem*, I'm just curious as to what the cause might be. I think it only ever does it during the startup sequence, but not during normal operation, which maybe suggests it's heat-related and "fixes" itself after the printer's been on for a little while. * if it's something such as a ROM going bad then it might become more serious - although the fact that the repeated chars are dimmer than the normal ones suggests to me that it's a problem somewhere in the display output stage rather than core logic. cheers Jules

MicroVAX issues

by b4＠gewt.net

Hello all, I'm having trouble with a MicroVAX 3100 of unknown model. (It's a KA41-A one, that's for sure.) It seems to endlessly test itself with the LEDs being 1001 1011. I have removed all drives and the communications option thingy for testing. I have also removed the (likely totally dead) battery. Does this require 3.8V as well? Could I just rig up some AAs or similar in series or does it try to charge the batteries? Also: I need a CK-KA630-AA for my MicroVAX II...the one I have is corroded and attempts to clean it somehow resulted in it behaving...unpredictably. Any help greatly appreciated!

Take a look at the DigiBarn pages at: http://www.digibarn.com/collections/business-docs/apple-II-DOS/index.html (including last April's CNET story with a lot of background) and my scans of many of the documents (but not the source listings) And Len Shustek's blog entry at the Computer History Museum which also has the actual documents and FULL SOURCE of the October 1978 delivery all converted to text and corrected at: http://www.computerhistory.org/atchm/apple-ii-dos-source-code/ Anyone out there want to help try to assemble to binary and test on an Apple ][ or emulator? bruce

SCSI-to-CF bridges?

I'm thinking >specifically for DEC hardware (PDP-11, VAX or Alpha). > In 2008, I bought an Acard AEC-7720U 50pin SCSI to IDE adapter for EUR 60 plus an IDE to CF adapter from Hong Kong for less than EUR 2. Unfortunately, I think the price of the former has increased since. The setup works nicely with my Alphas to read CF cards directly and SD and XD cards via yet more adapters purchased in a camera shop (except for some unreliability reading the XD cards.) I've not done much writing. A PWS 500a I was given had an IDE disk in it and a 68pin SCSI to IDE adapter (also Acard) which seems to work nicely, although I have not tried booting >from it. > >Also given the fact I have a good supply of drives, how cheap can >such bridges be obtained?

I tried to give the Living Computer Museum parts from a RA81 that I disassembled. I also tried to give it away here and within the local SRCS group. I ended up giving the to RePC, a local computer recycler that has a small museum in one of their stores. I still have another RA81 and two RA82s. The HDA is the sealed assembly with the platters and heads and was sometimes (often?) replaced separately from the rest of the drive. The HDA is installed in a chassis that forms the rest of the drive and mounts in a standard rack. The drive motor, the logic boards, front panel switches, power supply, etc. are inside of the chassis, outside of the HDA. alan

Looking for a MicroController Recommedation

by robert.jarratt＠ntlworld.com

I have been mulling a project to emulate MFM disks (DEC RD53 and RD54 in particular) at the disk-to-controller interface. Before anyone asks, I don't want to interface to Qbus (or any other bus) because I want to emulate the least possible hardware and keep my RQDX3 cards working. And yes, I know this has been talked about many times before, but I want to actually start trying this out. My idea is to use some kind of MicroController, talking to specific interfacing logic that drives the lines, and using SD memory for the actual storage. I am considering two approaches: 1. Just record the flux transitions in memory and play them back. This needs me to be able to sample and drive the data lines from the microcontroller at 25ns intervals because the pulse width of the flux transitions is 50ns. This would need a pretty fast microcontroller, but is my preferred solution as it seems the most general. 2. Build custom logic that does the sampling and encodes/decodes the data in 8-bit bytes, so that the microcontroller would only need to read data at a rate of 1 byte every 1.6us. I'd prefer not to do this as it requires me to understand the encoding (not too hard I suppose) and build custom logic, and makes the solution possibly a little less general. I would need a development board that makes it easy to interface to the SD memory on one side and to the custom interfacing logic on the other side (perhaps with a serial interface for debugging too), remembering that there is a 50-pin connector, although only 20 of these are signals, the rest are either reserved or ground. I would need enough onboard memory to store a whole cylinder which is just over 150Kbytes on the RD54. If I am successful I would then like to be able to make several more of the devices, so I would need something that is not too expensive to replicate. I am not sure at this point whether development boards are a good idea for the replication or if I would need to then source the actual microcontroller chips myself and make my own boards. If I have to make my own boards then I would need a microcontroller that is available as a DIP because I am pretty sure surface mounting is going to be beyond me; it would also have to be simple enough for me, who is not an expert in electronic design, to build the other components like the volatile and non-volatile memory, SD interface etc. Looking for recommendations for a suitable microcontroller that does not cost the earth ... Thanks Rob

Free: MS-DOS and early Windows software & docs

by snhirsch＠gmail.com

I am drowning here. If anyone wants it you can pickup free in Burlington, VT. Unfortunately I'm very much not retired and simply don't have the time to deal with shipping. There are probaby 2-3 large storage bins of boxed product, docs without software and software without docs - and, gasp, software WITH docs! There's a limit to how much one can accumulate and I think I'm past it :-). For extra credit: I can probably arrange to hand over a fair amount of miscellaneous junk, err, classic stuff if you have the room to take it. Take advantage of this special offer before the snow flies! Steve --

followup on NOS DEC CRTs -

by jack.rubin＠ameritech.net

As a follow up to Chris' posting, I have put together a group buy and we have now sold more than 35 of these tubes;? at this point, you can order as few or as many tubes as you wish as long as stock is available. If you want in on this, funds must be in my PayPal account - j at ckrubin.us - as soon as possible but no later than Thursday, November 14. Please send funds "To a Friend" so I don't get charged a PayPal fee for doing this pass-thru ordering! I will place an order on Monday, November 11, and then again toward the end of the week and the tubes will be shipped to you directly from EMI. If you have a phosphor color preference, let me know and I'll forward that to EMI, but no guarantees as to color or anything else. ? Usual disclaimer - I have no financial interest in this transaction or in EMI Solutions - I'm just trying to save these tubes from being scrapped. ? Jack

NOS DEC VR201/VT220 CRT tubes

by chrise＠pobox.com

EMI Solutions is going out of business and is clearing stock. They've offered to sell these tubes - DEC P/N 70-19578 VT220 TUBE & CRT ASSEMBLY for $37.50 + $15 shipping/ea or bulk qty of (10) for $250 including shipping in the US. They will ship internationally but contact them for costs. Jack Rubin and I have already purchased a few and they are as advertised, new-old-stock, shipped in the original carton with foamed-in-place support. The part number actually crosses to a VR201 CRT + bezel assembly but the bezel is easily removed by loosening a single screw. The VT220 and VR201 CRTs themselves are interchangeable. Phosphor colors are white, green and amber, subject to availability. I have successfully swapped the tube in an old VR201 that suffered from severe "cataracts" and it was about a 10 minute job. The monitor now works and looks great-- other than the color mismatch between the very yellowed housing and the fresh DEC beige of the new bezel. Good deal-- move quick as unsold units go to scrap at the end of the month. Contact Claudia, <webmaster at emisolutions.com> Nothing in this for me other than helping people keep their VR201 and VT220 looking sharp and these tubes from going to scrap.

SCSI-to-CF bridges?

by healyzh＠aracnet.com

Does anyone have any experience with replacing aging 50-pin (or even 68-pin and SCA) SCSI drives with a SCSI-to-CF bridge? I'm thinking specifically for DEC hardware (PDP-11, VAX or Alpha). Also given the fact I have a good supply of drives, how cheap can such bridges be obtained? Believe it or not, part of what I'm thinking of is noise. Of course on the PDP-11 front I booted RT-11 on a Raspberry Pi for the first time yesterday, and was quite pleased with the performance. Zane -- | Zane H.

S-100 bus extender PCBs ordered!

by LYNCHAJ＠YAHOO.COM

Hi Thanks everybody! There are now enough pre-ordered S-100 bus extender PCBs so I ordered a batch. They should be here in early December 2013. There should be plenty of boards available so if you want to pre-order yours feel free. These are the nice S-100 bus extenders with logic probe, signal ports, grounds, indicator LEDs, fuses, etc. They are very handy for system debugging and are improved over the last version. Thanks and have a nice day! Andrew Lynch

Welcome to the Goodwill Computer Museum

by lproven＠gmail.com

Goodwill Industries rehabs computers and sells computer parts, at least in Austin, Texas. The Goodwill Computer Museum is a natural outgrowth of that effort. In this video, museum curator Lisa Worley takes Slashdot's Timothy Lord on a tour of the museum. Remember that TRS-80 you threw away in 1982? Well, they saved several of them to stimulate your nostalgia-based pleasure nodules. Ditto many other devices both common and rare, including a pre-Dell computer made and signed by Texas computer celebrity Michael Dell. So sit back and enjoy the ride, as Timothy does the walking and Lisa does the talking, kind of like Night at the Museum -- but without CGI dinosaurs and other life forms getting between you and the classic computers. http://hardware.slashdot.org/story/13/10/29/1823212/welcome-to-the-goodwill… -- Liam Proven ?

I have used that connected through a CMD CQD-220 to boot a PDP-11. It's a multiple slot multiple LUN device so you need a controller which can support multiple LUNs if you want to access anything other than LUN 0, which is the PCMCIA slot (which of course can be used for a CF card in an adapter instead of using the CF slot directly). The PCD-50B doesn't appear to be too easily available now, nor the PCD-60B. I have heard of people using the CF PowerMonster / CF AztecMonster which typically go for around $130 on eBay. I haven't used one of those myself.

Even a 128M compact flash card in my uVAX2 would be awesome, both for power consumption reasons and speed.

VM/SP Manual Set

by BHuntsman＠mail2.cu-portland.edu

Landed a truckload of VM stuff last weekend. Amongst the items, and near-complete set of VM/SP manuals. Anyone interested in these?

DTL tape leader replacement

by mark＠wickensonline.co.uk

Hi folks, Has anyone had any success creating a DLT tape leader - I bought a very cheap DLT V80 off eBay which came missing a leader and I don't really want to spend any money on one. I have a TK50 leader which I can use as a pattern part, I wondered if anyone had come across any material that had similar properties? It feels like 35mm film wouldn't be a bad substitute for a replacement for example? Regards, Mark. -- http://www.wickensonline.co.uk http://hecnet.eu http://declegacy.org.uk http://retrochallenge.net https://twitter.com/#!/%40urbancamo

S-100 Bus Extender PCB pre-orders

by LYNCHAJ＠YAHOO.COM

Hi!? We are at 15 of the necessary 20 boards for an order of S-100 bus extender PCBs. Please send me your pre-orders and once we get to 20 boards I will make the manufacturing order for the group. I would like to get this going for the builders so if you are considering an S-100 bus extender or even want to stash one away for future use. These are very useful boards and sometimes they just get stuck in a project and stay there for extended periods of time. It is handy to have more than one at least in my experience. Here is a link to S100computers.com website with information on the updated S-100 Bus Extender board: http://www.s100computers.com/My%20System%20Pages/Extender%20Board/Extender%2 0Board.htm The PCBs will be $20 each as per the usual arrangement.? Shipping in the US is $3 for a single PCB and $2 for each additional PCB.? Shipping internationally is $10 for a single PCB and $3 for each additional PCB.? This is for the bare basics USPS first class postage with no tracking or insurance.? The builder assumes all risk of delivery as per usual arrangement. Please send a PayPal to LYNCHAJ at YAHOO.COM with the subject ?S-100 Bus Extender? and I will reserve your board(s).? Thanks and have a nice day! Andrew Lynch PS,? We are still doing another order for S-100 Buffered Prototyping board bus and have 6 boards in the queue.? If you would like one or more S-100 Buffered Prototyping boards please let me know.? The pre-order arrangements are identical to the others but please send them in a separate email with subject "S-100 buffered prototyping board" so I can keep things straight on this end. This seems to have stalled out so I am considering issuing refunds and waiting until there is more builder demand. At the moment we have 7 pre-orders and need another 13 to get to 20 board pre-orders. Thanks and have a nice day!

Getting rid of an Amiga 2000 and Amiga 3000 systems

by dgahling＠hotmail.com

I have one Amiga 2000 and one Amiga 3000 computers, they were working, and have been in storage. I have no monitors to test them with, but they do seem to power up. I'll take best offer, and I'm in toronto Canada. BTW I still have a bunch of suns (mostly sparc 5s), vaxstation 4000s (no drives), and an Octane. Though I have one sun sparc 10 ultra with the 486 board This stuff has to go. Over the next few months I'll probably be getting rid of more odds and ends, need to clean out the garage, and I'm broke, usual story. Dan.

Cory, Caution, wild-ass debugging guesses based on insufficient data follow. Fred's was the correct response, "what is it doing?" That said, I had trouble with one of these machines, and finally traced it to the power-on-reset mechanism. There are a capacitor and resistor in parallel, holding the CPU in reset long enough for power to get up and stable. The resistor was fine, the surface-mount capacitor was intermittent (grr!) short. So the machine would run for an indeterminate period before the capacitor would short, pulling it back to reset state. Replacing the cap fixed the problem, though I have not played with the machine much since. I think at least some of this story is in the archives, not sure. YMMV of course, but this sounds like a possible analog to your trouble; if your equivalent cap is dead short, the CPU would never get out of reset and the machine would look "dead" even with power. Let me know if you need more info, I can pull the box out of storage and try to look it over and test again. Good luck! -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

SCSI Tape boot

by sander.reiche＠gmail.com

Hi all, I've created a .TAP file using E11 which contains a bootable RT-11 image. I wrote this using st.exe to a DAT tape via my Adaptec 2940UW. E11 boots this fine, no matter the type of the MU0 device within the simulator. But if I try booting it using a CQD220A/M/T in /T mode, I get a "?BOOT-U-I/O error" which seems RT-11 enough to make me think it is actually trying to boot MSBOOT.BOT. The .TAP file was creating using E11's TU81 emulation and MUB.COM within RT-11 V05.06. A console log follows: KDF11B-BE ROM V0.9 1024KB MEMORY 9 STEP MEMORY TEST STEP 1 2 3 4 5 6 7 8 9 TOTAL MEMORY ERRORS = 0 CLOCK ENABLED 1024KB MEMORY KDF11B-BE ROM V0.9 CLOCK ENABLED ERR 12 NON-EXISTENT CONTROLLER Use CTRL/Z to return to MAIN MENU 173402 @17760406/005500 123456 @/001000 100 @5000g SCSI UTILITY PROGRAM 2.0 DISK TAPE 1 = 772150 A = 774500 2 = 760334 B = 760404 3 = 760354 C = 760444 4 = 760374 D = 760504HELP 5 = 760340 E = 760544 6 = 760344 F = 760410 ARROW" or "DOWN ARROW" to select function 7 = 760350 G = 760450 8 = 760360 H = 760454u SELECT CSR ADDRESS b MAIN MENU: CSR = 760404 1 = BOOT DRIVE 7 = ADDITIONAL SCSI COMMANDS SELECT OPTION : 1 BOOT DRIVE NUMBER <0 TO 7>: 0 BOOT MU0 .

Find a copy of the 9900 Family Systems Design Guide for more info e.g. at https://archive.org/details/9900MicroprocessorSeriesFamilySystemsDesignData… There, you will learn that the TI 9900 family (whose processor chips included the 9900, 9989, 9995 (?), and others) was a bit of an oddity in various ways (though that particular manual was first class). One oddity was its IO mechanism, using a single-bit-wide serial IO bus called the CRU. IO chips designed for the CRU bus (including the 9901 "system controller", and the 9902 UART, and many others, were realistically only usable with other 9900-family chips. The 9900 architecture was used in the 990 family of "minicomputers" including the 990/4 and its bigger brother the 990/10. TXDS was the "OS" (being generous again here) on the /4; something called AMPL ran on the /10. There are some pictures around the net, and a few writeups. I can't tell from the one picture (where is the other?) if that's what you've got, and I can't remember whether the /4 we had at work used the 9901 and/or 9902 on its serial cards. There is a 990/4 Maintenance Guide (and other 990-family stuff) on bitsavers which might be worth a look, at or near http://bitsavers.trailing-edge.com/pdf/ti/990/990-4/ The TI99/4 and related home computer boxes are very different physically although likely use chips from the same family. Apparently there was a range of external peripherals. You'll work it out. Have a lot of fun, John

1Tbit 'laser optical recording medium'

by jplist2008＠kiwigeek.com

While reading the wikipedia article on the ILLIAC IV there's a curious excerpt relating to the disk media: "They also provided a Burroughs B6500 mainframe to act as a front-end controller. Connected to the B6500 was a laser optical recording medium, a write-once system that stored up to 1 Tbit on a plastic disk covered with a thin metal film." Anyone know what this device was?

CPT Phoenix Start, looking for docs and floppy to start from

by Bernhard.Wulf＠shell.com

Dear Classiccmp community, After a long time of searching on myself with only minimal results on the "CPT Phoenix Start" - system, I would like to tap the collective knowledge. The system (powersupply + mainbox (3.5"floppy) + keyboard (with an interesting shape) + portrait full page screen) itself is fine, tries to boot, has a daisy-wheel printer and is only missing the 3.5" boot media. I have only the bare hardware and a couple of cables, assume it was used in professional word-processing. Appreciate any pointer. Mit freundlichen Gr??en, With kind Regards, Bernhard Wulf

The time sensitive bus interface logic was programmed into the FPGA. The built in ARM Cortex M3 runs uC Linux with a device driver to talk to the FPGA logic and a small application to supply the paper tape image. You could do the same and put the disk controller logic in the FPGA and have an application running under Linux to supply the read/write data functions. You could use the same disk image that the emulators use and store it in flash. -- Michael Thompson

It's more expensive that something like a Beagleboard, but TI has a line of ARM processor + TMS320 DSP chips (like the TMS320C66x series) that seem like a perfect fit for this application. Use the DSP portion to capture/pre-process the bitstream and the ARM to interpret, structure and store it. Just a thought. KJ

Is the urge to not name E11 "V7.0-07" something to do with RSTS/E or UNIX, or something else entirely? Cheers, Christian

Ersatz-11 PDP-11 emulator V7.0

by wilson＠dbit.com

Ersatz-11 V7.0 is done. This is the 20th anniversary release (development began on 31-Oct-1993), and it's got a bunch of new goodies. The free demo versions (for DOS, Linux, OS/2, Stand-alone, and Windows) can be downloaded >from www.dbit.com. There's a *lot* of new code. If that means there's going to have to be a quick update it's going to be hard to resist calling it "V7.0-07". There's no one huge new feature, but lots of little ones: - CR11/CD11 punched card readers - DMR11/DMC11 network ports (speaks real DDCMP to DECnet/RSX's software DDCMP) - DN11 autodialer - KG11A CRC boards - DU11/DUV11 sync SLUs proof-of-concept (but Z85230 driver needs finishing) - SCC: driver for Sealevel sync boards (see above -- at least async works) - Ridiculously improved VT100 emulation. Smooth-scroll and blink on OS/2 and Windows. Also SET-UP mode. Try pressing SET-UP (default = Shift/Esc) and then 0 on OS/2 or Windows for a good laugh, if you remember the real thing. VT100 w/o AVO, VT101, and VT102 emulations are now included (the autowrap behavior differs on all three -- thank you Will Kranz for the VT102 for testing). This was motivated by finding that the VT100 emulation was failing the VTTEST suite, but further investigation showed that a real DEC VT100 "fails" too, in a fairly similar way (virtually identical now). - ASSIGN ... /TTSYNC switch adds driver-level XON/XOFF flow control for output to most serial device types (and is enabled temporarily during all commands -- you really need it if smooth-scroll is turned on). - Scrollback buffer in VT100 sessions -- finally - HAYES: filter driver for data-leads-only modems with Hayes AT command set (turns commands/responses into modem control/status leads, and connects to the DN11 emulation) -- yes this would have been more useful in 1993 - OSPRINT: driver (emulates dumb line printer using OS-supplied printer drivers in OS/2 and Windows). Optionally adds green-bar-paper underlay, which seems silly until you see how nice it looks in CutePDF. OK it's silly. - Unit number ranges in ASSIGN/DEASSIGN, MOUNT/DISMOUNT, and SHOW -- Tries to be clever about incrementing unit numbers for the PC device: ASSIGN YZ0-3: COM1: (or /dev/ttyS0) gives you 4 DZ lines using 4 COM ports MOUNT DU0-1: rsx0.dsk gives you two disks using rsx0.dsk and rsx1.dsk *But* if there's nothing to increment then you get identical devices: ASSIGN YV0-15: TELNET: gives you 16 DHU lines on the same Telnet server MOUNT DC0-3: RAM: gives you a fully fleshed out RC11 (four RAM disks) - Generic host-OS-independent names for several kinds of ports that can be autodetected. SHOW ASYNCPORTS, SHOW PRINTERPORTS, SHOW SYNCPORTS, SHOW DIGPORTS, SHOW GPIBPORTS gives you a list of what ASYNCn: etc. will get you right now. This is supposed to make E11.INI files a little more portable (so you don't have to change COM1: to /dev/ttyS0 etc.). - Host-OS-independent NULL: devices for most device types. - IEU11/IEQ11 dual GPIB port bare framework (proof of concept: works only with NULL: device, does no actual I/O, but accepts many commands and LOGs their behavior) - RAMdisks now take their default size from the drive type (which may itself be defaulted) - "Short" disk images have the missing part emulated as a null area (so it's OK if the bad-block track wasn't included in the image -- you don't get errors if you touch it anyway) - DB:/DR: (Massbus moving-head disks) now enabled in Demo version; also OA:/XA: (DR11C/DR11W), used as Ethernet IPL, internal mP IPL, or simple LPT port interface - Raw floppies (PC formats, for now) on Linux, OS/2, and Windows - /CYL/HEAD/SECTORS switches work on all C/H/S disks - Disk logs now calculate the starting block number on C/H/S disks; LOG /PC includes PC in log files - SET ddcu: READONLY / READWRITE can write-lock or write-enable most disks and tapes w/o re-mounting them - SET IDLE DELAY=n adds a n-millisecond delay during WAITs - More use of helper threads (keeps long searches in .TAP files from interfering with PDP-11 execution -- and incidentally means that more of the PC devices are mP-safe even on the DOS and Stand-alone versions, since in that case "helper threads" means migrating DOS calls to CPA where it's safe -- not that mP is officially supported of course) - LoadModule, GetSymbol, and UnloadModule DLL calls (OS/2 and Windows) - Many, many, many bug fixes -- hopefully more than were introduced by the new code - The update disks will be CDs this time -- yes finally entering the 1990s John Wilson D Bit

Somewhat OT. 16702B Logic Analyzer Woes

by hp-fix＠xs4all.nl

HP 16700 series are known to be very picky about keyboards. If you use a ps2 Hp or IBM-M keyboard it should work fine. -Rik -----Oorspronkelijk bericht----- Van: "Pat Fitzpatrick" <pjfitzpatrick207 at gmail.com> Verzonden: ?2-?11-?2013 05:29 Aan: "cctech at classiccmp.org" <cctech at classiccmp.org> Onderwerp: Somewhat OT. 16702B Logic Analyzer Woes Hi Folks, It's only somewhat OT, because I really want to use this thing to fix a floppy controller (Northstar hard sectored all discrete logic type controller) in a classic computer :) Anyhow... I'm having issues with a (new to me) Agilent 16702B Logic Analyzer mainframe and this seems like the best place I can think of to ask.. It seems to work fine except the PS2 keyboard and mouse don't work quite right. Well, actually, the mouse does work -- if I use a Logitech USB mouse with a USB/PS2 adapter, it works fine. Any "real" PS2 mouse I own doesn't respond at all -- though the LED in the mouse is on. A Microsoft USB mouse with the USB/PS2 adapter doesn't work either. Seems strange. The keyboard on the other hand doesn't seem to work at all. The three LEDs (num lock, caps lock, scroll lock) blink during boot (like they're supposed to) and there are no warnings or errors I can see reported during boot, but the keyboard is totally dead. I've tried several keyboards, on one of them, the lights don't blink either. Even on the ones that blink, pressing keys during boot (to interrupt the boot process) has no effect. All mice and keyboards work (of course) on a PC. Any ideas on where to look? Or where to find good servicing information? Thanks, Pat

Anyone archiving Radio Shack PC1 software?

by ard＠p850ug1.demon.co.uk

As you may know, Radio Shack sold the Sharp PC1211 under the name 'Pocket Computer 1' (or PC1). They also sold pre-recorded tapes of programs for it (AFAIK, these were not Sharp products). Anyway, I've got the rpgorams from the 4 'Engineering Math' tapes and the 'Electrical Engineering 1' tape as plain ASCII files (BASIC progam source). Does anyone know of a website which archives such things, if so, I would be happy to provide them. Anyone interested? -tony

HP IIISi "55 SERVICE"?

This means that the Formatter cannot communicate with the engine in order to establish the initial condition of the engine. This problem can be caused by a bad Formatter, bad cable, or by problems with the line voltage. Check and reseat connectors J4 and J5 on the DC Power Supply, and J8, J9, and JIO on the DC Controller PCA. Cycle the power several times to clear the error or to get another error that may better indicate the cause of the problem. If this clears the error, run an engine test print. If the error persists, replace the Paper Pickup PCA, the DC Controller PCA, the DC Power Supply PCA, the Formatter PCA. Finally, replace the Paper Input Unit. If these fail to correct the problem, check all associated cahles for damage and replace if required. Any 57.1 Main Motor problem can also cause this error. I can copy & paste the manuals info on any other error messages you see if you'd like. Or convert the PDF to a TIFF file or similar if that would help. Bob

Random UNIVAC item...

by derschjo＠gmail.com

Hi all -- Grabbed this as it triggered both my "interesting numerical display device" and "old computer" reflexes: http://yahozna.dyndns.org/scratch/misc/univac.jpg It's labeled on the back (roughly, as things don't line up particularly well): Magtrol, Inc. DYNAMOMETER HDE-500 MODEL HD-705 SERIAL NO 511B341 TACHOMETER 811E342 MODEL SERIAL NO And riveted to the back is a placard reading "SER 2U02-2" Inside it's completely tube-based, no solid state electronics at all. Not counting the Dekatrons, there are 9 tubes in this thing, one branded "UNIVAC" on the base, the rest appear to be RCA. It looks like it contains an electronic tachometer of some sort. I can't seem to find a date code on anything. Any ideas on what this might have been used for, and how it would relate to UNIVAC? I can provide more pictures later if anyone's interested, once I get a chance to disassemble it a bit... Thanks, Josh

SF Bay - quick swap for a 3B2 or...?

by BHuntsman＠mail2.cu-portland.edu

I'm taking a quick weekend trip to the SF Bay Area to pick up a few things. Hoping to make the most of the trip, anyone in the area have any IBM gear they'd like to trade for a 3B2/400 or money? :) Also, they're not not exactly "classic", but I also have an HP blade chassis with 5 or so blades, a Google search appliance, and a near-complete set of Progress v9 manuals that I'd be willing to part with... -Ben

Early IDE interface for ISA bus, 1990

by axelsson＠acc.umu.se

I'm doing a bit of cleaning out of my collections (making space for a Data Point 2200) and one thing I found was an early IDE interface. I can't find out anything about where it came from and the silk screen says "Rev 0.0" and the pal program version is V1.0 Date codes on the IC:s points to an early 1990 date for manufacturing. I tried to find out some more about the development of the IDE interface and the two dates I found was Compaq introduced the first computers with IDE controllers in 1986 and the first standard was finalized in 1994, putting my card in the middle of that span. I put it on eBay to see if there is any interest for it and to show some pictures of it. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=111203086292 Any one recognizing it? Is it just a generic card or does it belong to a specific computer? /G?ran

Fwd: SPARK computer

by doug＠blinkenlights.com

Datavue Spark (one of the earlier laptops made) available in Maryland. Please contact the person below directly if interested. ---------- Forwarded message ---------- From: Sarah Flynn <SarahFlynn at comcast.net> Date: Wed, Oct 30, 2013 at 10:31 AM Subject: SPARK computer To: doug at blinkenlights.com Dear Doug? My husband, David Prosten, and I were recently clearing out some old stuff and came across his SPARK (by Datavue), ?first world?s first truly personal computer,? complete with Operations Manual (quote from manual) and diskettes, as well as a SPARK printer. The manual is copyright 1986, so I guess it would not be of interest to you (I gather you are only interested in pre-1981 stuff). But if you have any ideas where we might find a good home for it, we?d appreciate it. It seems too historic to just dispose of it. Many thanks, Sarah Sarah Flynn 3120 Munz Drive Annapolis, MD 21403 Landline: 410-268-2966 Mobile: 410-703-3990 SarahFlynn at comcast.net
