The > input looked great and the output was "half baked" There's no chip at all on the driving end of the line (just that 470K resistor); we see this with the SD card _unplugged_. And we see the exact same thing on several lines. I'm still not clear, from the discussion, how exactly that nice 'square-wave' interference is happening - could it be capacitative crosstalk? (I'd have thought capacitative cross-talk would be inverted - driving a positive voltage on one 'side' of the 'capacitor' would, I would think, induce an oppposing voltage on the other. But I'm clearly no EE! :-) Noel

Anyone want a Sun T-shirt?

by cclist＠sydex.com

It's what, 27 years old... Trying to de-junk my clothes closet, I ran across an XL t-shirt bearing, on the front, a image of a ladybug with a red circle and bar across is and the legend "Getting out the last bugs". On the back, it has the Sun logo and "SunStruck 4.1.89 (Wanda)". It's in decent condition and probably dates from the time my wife worked at Sun, even though she had nothing to do with the project in question. Anyone want it? Pay for first-class mail (I'll stuff it into an envelope) and it's yours. Otherwise, it goes to Goodwill. --Chuck

Cross-talk square-wave?

by jnc＠mercury.lcs.mit.edu

Hi, a question about generic analog stuff. In the process of getting SD cards to work, Dave is seeing square-wave noise on a line. (1V of square wave, with pulses about 400ns long, running at 375kHz.) The line runs through a flat cable of modest length, along with other signal-carrying lines. (No, we were not smart, and didn't put ground lines between each pair of signal lines!) Could cross-talk cause this kind of noise? We would have thought that you'd only get spikes, associated with the rising and trailing edges of a signal in a parallel wire, not a whole square-wave. During the constant-current period in the middle of the pulse, there shouldn't be any cross-talk? Is there some mechanism I/we don't understand that could do that? (My guess is there's a leakage path in the circuitry on one end or the other, not cross-talk in the cable, but...) Thanks! Noel

Floating point routines for the 6809

by spc＠conman.org

Some time ago I came across the MC6839 ROM which contains floating point routines for the 6809. The documentation that came with it stated: Written for Motorola by Joel Boney, 1980 Released into the public domain by Motorola in 1988 Docs and apps for Tandy Color Computer by Rich Kottke, 1989 What I haven't been able to find is the actual *source code* to the module. Is it available anywhere? I've been playing around the the MC6839 on an emulator but having the source would clear up some issues I've been having with the code. -spc

Cross-talk square-wave?

Exactly. That sort of cross-talk we understand (and have seen before). But a square wave? How can that be? That was the motivation for my original post. It's not super-critical to understand, because like I said, this is on a pre-prototype, and the actual unit will be arranged nothing like this (no cable, etc, etc), so we're just going to fix this with whatever kludge makes it go away, so we can focus on the things we really do need to work on. But we'd still like to understand what is happening here, and how. Could cross-talk (of whatever form, inductive or capacitive) do this, or does this more or less have to be signal leakage (on the board at one end, or the other) somehow? Noel

Model 28 Teletypes in Edmonton, Alberta

by rlloken＠telus.net

So, my ex-wife sent my Model 28 RO and Model 28 ASR (along with a Conn vacuum tube electronic organ) to the landfill yesterday. I am told by my son that they went to the Eco Station Reuse Area at either the Ambleside or kennedale Eco Station. So, in the unlikely event that somebody wanting a 28 tty and within travelling distance of Edmonton, Alberta reads this, those items are reported to be there for taking. Oh, and bring a truck and a very strong friend. -- Richard Loken VE6BSV : "...underneath those tuques we wear, Athabasca, Alberta Canada : our heads are naked!" ** rlloken at telus.net ** : - Arthur Black

Cross-talk square-wave?

by jnc＠mercury.lcs.mit.edu

I should mention that this is a pre-prototype; the final thing won't have a cable at all; so this isn't a fundamental issue with the design (if it is cross-talk). And the SD card isn't even plugged in when we see this - if it is cross-talk, it has to be some other signal carried in the cable. We're just trying to figure out how cross-talk can possibly produce an induced square-wave. Noel

PSU protection with resettable polyfuse

by binarydinosaurs＠gmail.com

Hi folks, The PSU for my Executel 8085 system is an Astec AC8151-01 40W 5A unit that puts out +5/+12/-12V. A while back somone suggested using an ATX PSU in its place which TBH I'd forgotten about untl I saw a breakout board that you plug a 20 or 24 pin ATX supply into and it terminates each rail in whatever you choose to solder in. ukp8, rude not to :) My only worry is an ATX PSU is capable of putting out a lot more than 5A if it goes wrong so I'd like to protect each rail with an appropriate fuse. Any downsides to resettable polyfuses? Cheers, -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home computer collection? www.binarydinosaurs.co.uk

Not Getting Emails

Microdata and Decision Data haul from usual site

by jwsmail＠jwsss.com

I was able to get hold of a lot of boards which had been pulled from two Decision Data's and a Western Dynex 2400 RPM 10mb (probably) drive. The Dynex drive is similar to the RL02 and in fact was configurable to look like one in one of the options. Microdata would have used 24 sector packs vs. the 12 sector packs used by DEC, however. One of the CPUs is a pretty ordinary Data / Control set made by Microdata but with most of the etch and silkscreen modified to have Decision data info. I'm going to check with my Microdata people and see if anyone recalls if this was done by Microdata, or by DD themselves. There is a nice find however, a 2901 CPU 16 bit system cpu set and memory. It also runs in the 130 pin Microdata 1600 backplane, which makes it interesting. I'd love to get information and drawings as much as might be around for this set. May be donating most of it to add to my 1600 system @ the CHM, as there are boards here which I didn't have examples of to donate at the time. Will check with them after I fondle the boards for a while. It's cool to have an additional example of a possible Microdata 1600 type CPU, as this is one of my collecting areas. I'll be adding in titles and comments on the photos later, but here are photos of the boards for now. http://jim-st.blogspot.com/2017/03/microdata-decision-data-and-western.html Thanks Jim

MC68K's on DEUNA's

by jnc＠mercury.lcs.mit.edu

> From: Bill Gunshannon > I doubt Motorolla was in the business of custom making different size > chips, even for DEC. So, that triggered a question in my mind: why was DEC using the 68K on this board, anyway? They had plenty of in-house chips the could have used, e.g. the J11. The MC68000 had only a 16-bit bus, so it's not that dissimilar in capabilities. Why buy out? Did Motorola offer them a price they couldn't resist, or what? Noel

Wanted: AT&T 3B2 Ethernet Card ROM images

by lists＠loomcom.com

I'm trying to track down ROM images from AT&T 3B2 expansion cards. I've started with the EPORTS serial card, which I have. What I'd love to find is the ROM from the NI Ethernet card. Not all ROMs were socketed. Freqently they were soldered, so I know that getting these probably won't be easy. If I had an NI card of my own I'd desolder the ROMs, but alas, I do not. If you have these ROMs, are willing to image them, or -- and this is a real long shot -- if you're willing to let me borrow a card for a while, I'd greatly appreciate hearing from you.

booting os/8

by w2hx＠w2hx.com

I got to the step tonight where I was trying to boot an OS/8 disk image and nothing was happening. I realized that I do not have the bootstrap diode board in my 8/e so begin the bootstrap triggered by the "SW" switch. Does anyone have the program I can toggle in for the bootloader? What I found is somewhat confusing. Here is a discussion on this topic. https://groups.google.com/forum/#!searchin/alt.sys.pdp8/RX01$20boot|sort:re… It seems one fellow was attempting to edit/improve the bootloader of another fellow. I was wondering if anyone has distilled this into something simple. At the moment, I care only about booting from RX01-Disk0. Any pointers greatly appreciated. Thanks Eugene W2HX

MC68K's on DEUNA's

So all the DEUNA's I've seen have L10 (ceramic package, 10Mhz) 68K's in them. Has anyone tried using anything else, and did it work? I _assume_ an x12 would work, but until someone has acutally tried it... The Pxx's (plastic packaging) might not work - according to the datasheet, they are 2mm wider than the ceramics (why, I have no idea - it probably means they aren't interchangeable, which makes no sense at all to me).

STC 2920 tapedrive schematics

Does anyone have schematics for an STC (StorageTek) 2920 reel-to-reel tapedrive? I?m trying to solve a tape-loading issue that seems to be power-supply related, and some schematics would be very handy right now? Camiel.

Looking to rehome an Atari ST Colour monitor

by bulk＠blit.ca

Hi folks, I have an Atari colour monitor for the ST series of computers that I'm looking to rehome. Model number is SC 1224, Version 2. I've never attempted to power it up and have no idea if it works. It's free to a good home, provided I don't have to put in a lot of effort. (I'm currently in the middle of packing for a move; I have very little spare time or energy.) I'm in the Toronto area. If anyone wants it, let me know. --Chris -- Chris Reuter http://www.blit.ca "Oh God Lem, you're using science for no good. We took an *oath* we would try to do that less." --Better Off Ted

GImix Ghost Video Board

by vintagecomputer＠bettercomputing.net

Hoping someone might be able to help me on this. I got a Gimix Ghost SS50 video board today and was trying to find a manual. I'm sure these were used in Gimix's own ghost systems but the very limited info I've come across out there suggests they may have worked with any SS50 system. It basically provides a direct composite video feed out from the computer, I assume bypassing the need for a terminal. I plugged it in and fired it up on my SWTPC 6800 and it is working - I think - it generates a full screen of readable random characters. However it does not put up anything from the computer - that still goes out via terminal. I'm assuming Ghost systems were wired up somehow to use this.. I'm hoping to find a manual that explains how. I don't see a keyboard interface for it anywhere so maybe this went along as a complete Ghost system with hardware I don't have. Thanks if you have anything!

Extracting files off “unknown” 8 inch disks. Any thoughts…

by terry＠webweavers.co.nz

Hi, I?ve posted this to the VCF too?apologies for cross-posting. I?d be grateful for any guidance or comments anyone could give me on this problem. Guys in the building next door to me (a Science lab) have found some 8 inch floppy disks. They want to see what?s on them, or at least to archive them. They have no idea what machine these disks were used with, or the software was used to write the files. They may be CP/M, or some other format entirely. I?ve got little experience with 8 inch drives or disk formats. However I have got a bare 8 inch floppy drive (a Mitsubishi M2896-63 Half Height 8inch DSDD), and also a CP/M computer with 8 inch drives (A Panasonic JD-850M). I?m thinking it might be an interesting challenge/project to see if I can read these disks and get files off. However, I imagine given all the unknowns it won?t be easy?perhaps even impossible I see two possible approaches. One is to wire up the 8 inch drive to an MS-DOS machine. I?ll have to build/get a PSU for the drive so it can supply the necessary 24 Volts required. I?ll also have to make up a special drive cable. That info is available. In fact, Chuck gave me some tips a year or so ago. However, once I?ve got the drive successfully wired up, I then need to somehow analysis the disks to see what format they are in. Does anyone know of any software that will do this? I?m aware of disk22, for reading KNOWN CP/M formats but is there anything out there that will analyse a disk from scratch? Search the web has thrown up a few possibilies (MMCPC, Cpmtools) but I haven?t explored them at all. The second approach is to use the Panasonic JD-850M, and find a CP/M program that will analyse an ?unknown? 8 inch disk and read files from said disks into the CP/M environment. I?d somehow get the program into one of my Panasonic 8 inch disks (just how, I?ll need to figure out). I?d also need to figure out how to get the files out of that environment also. Anyway, has anyone else faced this kind of challenge and what are your thoughts? I don?t want to start unless I at least have some chance of success. I?m not hopeful. The more I read the more you seem to need real forensic skills and something like Kyroflux that works at low-level. Thanks Terry (Tez)

Seeking schematics/maintenance prints for DMB32/T1012 and H3033 distribution panel

by ethan.dicks＠gmail.com

Hi, All, With all the recent chatter on the VAX8200 on the simh list, I was motivated to dust mine off and do a little digging. I finally took the plunge and got a DMB32 (right now, all I have are the 4 built-in console ports) but while it was easy enough to find the 8.5"x11"-format user guide and technical manual which describe registers and installation and problem diagnosis, I also want the internal cable pinouts and schematics. I know it's harder to find post-Unibus-era C-sized prints since DEC stopped shipping printsets with every order, so I have to ask, does anyone have any schematics for either the T1012 module, the H3033 I/O bulkhead board, or both? I can likely quickly recreate the schematic for the H3033, it's 10 D-shell connectors (8x DB, 1x DC, 1xDD) and 6 30-pin ribbon cable connectors. Lots of signals, but lots of repetition. The D-shell pinouts are in the documenation I already have. The 30-pin connectors/BI fingers are not. But if the schematics are already available, I don't have to buzz one out. http://manx-docs.org/collections/antonio/dec/dmb32ug1.pdf http://manx-docs.org/collections/antonio/dec/dmb32td1.pdf ftp://bitsavers.informatik.uni-stuttgart.de/pdf/dec/vax/vaxbi/EY-5554E-SG-0002_VAXBI_Adapters_Student_Guide_Feb87.pdf Thanks for any new docs. -ethan

Any faithful VT100 Emulators?

But the default terminal emulators of Gnome or KDE have some issues in my experience. xterm is always buried in the system somewhere though, and it works. I use it e.g. for accessing my old minicomputer which has a VT100 setting.

I do know that they came out with a version for OSX a while back. I expect that to be robust. There is a version for Linux, never tried that as I'm a FreeBSD zealot. There is also an iphone/ipad app by secureCRT and I've used it in a few pinches but never on a classic system. And the company has actually heard of VMS ;) Their support is off-the-charts. On more than one occasion I've emailed them asking for this or that... and several times I've seen it implemented on the next release. They actively listen and implement. If the linux and OSX and app versions are as good as the windows one... it's worth a shot. J

Any faithful VT100 Emulators?

OK, so I don't have a real VT100, so I'm accessing an old 4.3BSD system with xterm and LXTerminal terminal emulators on Linux. Last night, for a laugh, I ran vttest from the 1980s and the terminal emulators performed woefully. Which raises the question, are there any _good_ VT100 terminal emulators, especially for Linux? For any other platforms? Cheers, Warren

Suggestions why SCSI 80 drive w/ SCSI2 (50) adapter will not spin up ?

by pete＠petelancashire.com

Host is a HP 9000/382 Copied the orig drive using a linux box, adaptec 2940N and good old dd Then swapped drives, a unused 9 GB 80 pin with a Chinese 80 to 50 adapter. Did have to issue a spin up command and then copied the data to this drive again with dd. Powered all off, added a motor start jumper to the adapter and put it on the 9000/382. Motor will not start, added a jumper right on the drive, no spin. so .. any ideas what I'm doing wrong, or just try a different drive ? -pete

Timesharing/multiuser BASIC for MC68K

by jzatar2＠illinois.edu

I just wanted to share a little project I've been working on, it's an adaptation of Lee Davison's EhBASIC to become a timeshared multiuser BASIC. There's still a bit more to do, but here's a video of it in operation: https://youtu.be/SAJpHiBPMcQ In that video, it's only running 3 sessions (I had no convenient 4th terminal) but it's capable of running 4. It is a very very simple preemptive multitasking 'kernel' providing I/O services and performing periodic context switches for the instances of the interpreter. It only runs a fixed number of processes, and all the process memory is statically allocated. EhBASIC lends itself well to this, the code is position independent by design, and the memory range is passed in. Everything is dereferenced relative to the 'start of memory' pointer. This means no need for an MMU or relocation. I'm hoping to set this up at VCF MW in September, running 4 terminals. More info on the hardware I'm using is available here: https://hackaday.io/project/6150-beckman-du600-reverse-engineering Pictures: https://www.dropbox.com/sh/uw6cjqigk2sdwdy/AAAwP55aelyzrYeP1HVUDdMqa?dl=0 And another software project I'm working on as well (a ROM monitor program): https://github.com/jzatarski/Joe-Mon

I added an answer here: https://github.com/DoctorWkt/4bsd-uucp#joining-the-growing-uucp-network For central sites (like decvax) that had a lot of connectivity, you will be expected to run them continuously. For edge sites which only dial in to one other site to exchange news and e-mail, you can run them whenever you want. It's mostly simulated sites right now, but I'd love to see some real systems come up and connect in. Not sure how to connect the simulated sites (using TCP for the dialup links) and the real sites.

TRS-80 Model 1 Expansion Interface question?

by wheagy＠gmail.com

I have a clean, and somewhat functional expansion interface that I just tested over the weekend. Without the EI connected, the model 1 reports ~16K RAM and with the EI the model 1 reports ~48K, so the RAM seems OK. But, the FD1771 IC, for some reason, was removed from an otherwise apparently functional EI. http://imgur.com/a/3NzOh Is there any reason why this chip would be removed? I see a number of them on ebay for around $25. The expansion interface hardware manual indicates it is an FD1771B-01, but the service manual indicates a couple possibilities....FD1771 A/B -01 -11. Any considerations to look for here? Thanks, Win

Looking for article: microprogrammed DIY TTL calculator

by jacek.greniger＠gmail.com

Hi, Two years ago I've found scans in PDF with the article (dated 197?, I don't remember) describing DIY TTL-based calculator. This was microprogrammed machine (if I remember correctly microproprogram was "stored" in the diode array). It has LED display and possiblity to calculate square root. Definitely not talking about EDUC-8 computer from 1975. I think this calculator was published a little bit earlier. Unfortunately I'm no longer able to find it. Does anyone associate the name of that magazine? Regards, Jacek

Pair of Twiggys

by jnc＠mercury.lcs.mit.edu

> From: geneb >> When people decided Steve Jobs had become a god? > Right about the time that whole "computer for the rest of us" started... Yes, of course: nobody had thought of a cheap personal computer before him. (Which reminds me, does the CHM have a Datapoint 2200? If not, we really out to try to round one up for them.) Or even a personal computer. (Ditto for the LINC.) Although I suppose you might have been talking about the software. I mean, without that whole display/windows/menu/mouse thing he invented, to allow ordinary people to use a computer, where would we be? Look, I fully admit that Steve Jobs was a _very_ sharp person who had a _tremendous_ influence. (Every time I hear someone saying marketing people are useless - first up against the wall, etc - I reply 'No, only bad ones - which is a lot of them. The very best ones, like Steve Jobs, are worth their weight in triple-refined iridium. A _good_ marketing person can tell you what customers _want_. A _truly great_ one can tell you what they _need_, but don't yet even realize they do.') However, the people (and there are quite a few of them) who have gone way off the deep edge, and have turned him (and Apple) into some sort of overblown cult, just don't have a balanced perspective. There are plenty of people out there who deserve at least as much credit for the information society we now live in, who are almost totally unknown to the population at large; starting (probably) with Licklider.

LGP-30 Update

by coryheisterkamp＠gmail.com

Hey guys, figured it was time for an update on the LGP-30 resuscitation. Some further detective work found a leaky 1500uF cap in one of the B+ supplies which was causing the 'surging' issue on the scope. For good measure I replaced all six 1500 and 3000uF caps even though ripple was low. Better safe than sorry and if it means pulling that chassis and its covers again, all the better. I attempted to weigh it on my shipping scale, but it only registers to 100 lbs and the indicator flew right past that. There had been a small thermal event in the AC junction box that the twist lock connector mounts to, and I suspect it occurred pre-60's refurb. It's not too surprising as the wiring on the computer side is aluminum and the feed is copper. The box needed replacing but was a unique Hubbell variation of a std 4" box with special ears. I couldn't find anything even close to that at any of the supply houses online, probably because it violates today's conductor fill rules (it's only 1" deep but the socket consumes most of that depth and 75% of the area). I eventually settled on drilling/tapping a standard box and cleaned up the wiring. The sequencer unit is now working correctly after I found an NOS relay to R&R contacts with. The blower is still steady and quiet with its new bearings, and no issues (knock on wood) with the drum after greasing the end bearing, belt and 'tightening' up the tolerances on the timing and short register heads. Some good news- I now have three horizontal lines on the scope, rock solid and where they should be. I can get the occasional pattern for Instruction contents, but Order and Accumulator still aren't reading/writing/displaying. All in good time. http://radar58.com/LGP30/wp-content/uploads/2017/03/lgp.jpg Even better news is that the three timing tracks appear to be intact on the drum and the supporting hardware is working. http://radar58.com/LGP30/wp-content/uploads/2017/03/scope-e1489957963176.jpg (1, 2 and 3 correspond to S1, S2 and S3) Now to investigate those short registers... -Cory

8085 RESET

by witchy＠binarydinosaurs.co.uk

Hi folks, 8085-based phone system weirdness continues and I'm beginning to wonder if the PSU rails are all coming up in time for RESET to go high - given there's 4116 DRAMs in there isn't there supposed to be a proper power up order? While I look at using a 20-pin ATX PSU to run this machine temporarily I need a safe way to reset the CPU rather than constantly power cycling. The RESET line comes from an ICL7611 op-amp via an MC14081B through pins 1-4 of a 74LS04 and I need to pull it low for longer than 3 clock cycles. I wish I had a schematic to show!

Extracting data from DEC VAX tape recordings

by will.pearse＠usu.edu

Hello, I'm sorry to bother you, but I was hoping you might be able to help me with a problem I'm having getting hold of some scientific data that's currently stored on DEC VAX magnetic tape. A colleague of mine carried out some ecological fieldwork ~30 years ago, and her results are stored on eight magnetic tapes (two of 7" diameter, one 8.5", and five 10.25"). The data would be incredibly useful to look at, as the study was looking at how restored mines changes over time (the study is somewhat described here; https://www.jstor.org/stable/20038221?seq=1#page_scan_tab_contents). If we could get these original data, we could compare how the mine is now with how it was then, which would be phenomenally useful to conservation biologists trying to conserve and restore damaged ecosystems. Do any of you have any ideas as to how I might get the data off this tape? I live and work in Utah (USA), but I would be willing to travel a little ways if it meant getting the things read off into a computer! Thanks again for your time, Will Pearse --- Need a phylogeny?

CF cards as storage - wear leveling

by jules.richardson99＠gmail.com

I just bought an IDE-CF adapter the other day with the intention of replacing the spinning rust in my disk imaging system (which is some early/mid-90s 80486-based thing). However, the CF entry on Wikipedia says: "Most CompactFlash flash-memory devices limit wear on blocks by varying the physical location to which a block is written. When using CompactFlash in ATA mode to take the place of the hard disk drive, wear leveling becomes critical because low-numbered blocks contain tables whose contents change frequently. Current CompactFlash cards spread the wear-leveling across the entire drive. The more advanced CompactFlash cards will move data that rarely changes to ensure all blocks wear evenly." ... I'm a little wary about the way it says "most CF cards", implying that there are some out there which don't do any wear-leveling at all. So, the obvious question: is there a way of knowing which cards are going to be good and which are useless as IDE replacements? Maybe by age, capacity, manufacturer? I'd prefer not to invest time into setting software up only to find that the card fails in a matter of weeks. cheers Jules

LINCtape/DECtape Head Alignment

by michael.99.thompson＠gmail.com

The RICM is working on the skew adjustment on a TU56 tape drive on a PDP-12. We only see a 5mV signal from the head, so when we flip the tape over we will only see 1mV. This is below the capabilities of my 'scope. The DEC skew adjustment procedure talks about using a DEC amplifier to boost the head signal to several volts. We are planning to make an equivalent amplifier using a modern Op-amp. It would be really convenient to have one of the Amphenol 133-022-03 connectors from a G851 Relay module on our amplifier so it would plug directly into the head cable. Does anyone have a DEC G851 module that we could remove the connector from? -- Michael Thompson

User group magazine scans for an orphan computer model

by terry＠webweavers.co.nz

I've been scanning some user group newsletters. Reading them today reveals just how important they were for orphan machines home computers like the EACA Colour Genie. Even if you're not interested in that model, they are worth a look as they do reflect the "user club" scene of the day. I'm assuming New Zealand was much the same as anywhere else in this regard. Somewhat quaint, they reflect a bygone era. http://www.classic-computers.org.nz/blog/2017-03-18-eaca-colour-genie-auckl… Terry (Tez)

HP 9000/382 Questions

by pete＠petelancashire.com

Hello from a newbie to the list I've just acquired 2 HP 382's with expanders. Have not had the time to look inside them yet. End goal is to set one up as an instrument controller i.e. using the built in GPIB and potentially a 2nd GPIB card. One thing I do not have is a display, keyboard and mouse. A few question Is there a PS/2 or USB (yea long shot) adapter for the HPIL interface ? Does someone have a keyboard/mouse they a not beholding to, or know where there maybe one ? Once I get the opened up and take an inventory, anything I should look out for be trying to power one of them up ? Can one boot to a terminal on the RS-232 port. Until I find a kbd/mouse ? What would be optimum version of HP-UX to run on them ? -pete

Looking for an Intel SRM

by camiel.vanderhoeven＠vmssoftware.com

Here?s a long shot, about as long as they get. I received an Intel iPSC/860 supercomputer, but it?s lacking the Intel SRM (System Resource Manager), without which the system is a boat anchor. The SRM is an Intel 386 desktop machine, with a SYP301 motherboard and a plugin card to connect it to the iPSC/860. There?s a cable coming from the iPSC with a 25-pin D connector, which I believe is the connection to the SRM. It?s not a regular serial port, but a bidirectional 2.6MByte per second connection. The interface card likely uses a bunch of Xilinx chips (the interface cards on the iPSC node boards do). I have not been able to find a picture of what the box looks like on the outside, so I have no idea. So, I?m looking for one of these, preferably one the owner would be willing to part with :-) Camiel

DEC frontpanel switch replica!

by hachti＠hachti.de

Hi folks, this might be quite interesting for the folks that miss front panel switch handles! As some of you might know I'm currently working (a bit) on a new batch of Omnibus USB boards. And I have announced that there will be a kind of handle for the boards this time... I went to my neighbour and showed him some bits and pieces. He has a nice little workshop for concrete artwork (https://www.fritzundfranz.com/) and spent a lot of time into perfecting his moulding skills. I gave him a pdp8/e yellow switch handle with broken axle (usual problem) to try what can be done. Today I came home and he gave me the piece saying that he was unable to replicate it. I took it (a bit frustrated) and stated that he has somehow ruined the surface... Haha! It was the replica! He told me that this was a first "fast" shot including a "rough" approximation of the colour. I was stunned! Here you can see pictures. Even the defects of the original have been replicated. https://www.dropbox.com/sh/sih4qrrw4o3zgbh/AACf7kY7MbGDLt5FYJgfI4kDa?dl=0 He told me that it was a bit difficult to get the holes at the side right. I think that it would be no problem if they'd be more shallow or even gone. * His material is less translucent than the original. Won't probably change. So a perfectionist could spot the difference. * He states that he can hit colors even better! (Think of the special colors!!!) * The axle stubs would be omitted and made of steel (something I already plan for repair of that weakest point) * He is able to produce flawless finish (remember: it's a raw prototype!) This is not my business. I told him that I'd ask around if there would be serious interest. He is not in vintage computing and does not work for free. So one piece would probably cost around 5-15 EUR each, depending on demand, color etc. Please give some feedback! Philipp :-)

Ardent Titan

by camiel.vanderhoeven＠vmssoftware.com

Last Friday, I finally received a shipment of 1980's minisupercomputers >from the US that I've been working on since September. One of the systems is an Ardent Titan, which to my knowledge was the first (mini-) supercomputer to come with an integrated high-end graphics subsystem (1280x1024 at 60Hz, hardware spheres, antialiasing, and cast shadows). After careful checking, I powered it on yesterday, and got as far as trying to boot it; unfortunately, the harddisk does not contain the OS, but I'm trying to get access to an installation tape. There's a full writeup about my efforts this weekend on my website: http://www.vaxbarn.com/index.php/42-repair/576-ardent-titan-power-on A description with some pictures of the Ardent can be found here: http://www.vaxbarn.com/index.php/other-bits/565-ardent-titan Uncrating pictures are here: http://www.vaxbarn.com/index.php/41-acquisitions/575-supercomputers-have-ar rived Anyone who knows anything about these machines, please contact me! Also, if you have access to installation tapes, manuals, brochures, anything related to these systems, please let me know. Kind regards, Camiel Vanderhoeven

Delay Lines (Was: Univac I memory tank)

by rickb＠bensene.com

Dwight wrote: > The Olivetti used a piece of wire for the delay line. The Programma 101 indeed used a delay line. Such delay lines use magnetostrictive means to push a torque pulse into one end of the wire, as well as detect a torque twist at the other end of the wire. Magnetostrictive materials are typically a metal alloy that lengthens or shortens depending on the polarity of an external magnetic field, and will also generate a small magnetic field if stretched or compressed. In a magnetostrictive delay line thin strips of magnetostrictive metal are attached to opposite points tangential to the circumference of the end of a nickel-alloy(typically) wire. These strips, for whatever reason, are typically called "tapes". Each tape has a small coil of magnet wire surrounding it, wound oppositely around each tape, such that when a short current pulse is sent into the coils, one tape momentarily lengthens, and the other tape contracts, causing a slight but sharp twisting torque to be applied to the wire. This acts to transmit a pulse of energy into the wire. The torque twist mechanically travels through the wire to the other end, where it causes one tape to lengthen slightly, and the other to compress slightly, which induces a small current pulse into the coils around the tapes, which can be amplified to match the electrical characteristics of the original pulse. Sending a current pulse through the coils in one direction causes the twist to occur clockwise, and the pulse going the other direction induces a counter-clockwise twist, allowing ones and zeros to be pushed into the wire as clockwise or counter-clockwise torque twists. The amount of time that elapses (delay) from the pulse being injected to being received at the other end of the wire is based on the metallurgy of the wire, and its length. The wire is capable of remembering some number of torque twists as bits, with a clockwise torque, for example, representing a one, and a counter-clockwise twist representing a zero. The wire was typically arranged in a spiral inside a metal housing. Silicone or rubber supports supported the wire without attenuating the torque pulses in the wire. In some cases, there were "taps" along the length of the wire that used the same transducer method to pick off bits at different delay periods. The use of such delay line technology in calculators arose out of the need to store a moderate number of bits to represent the working registers of the calculator. At the time, magnetic core memory was still quite expensive, integrated circuit technology was in its infancy and too expensive to use for mass storage in a calculator, and it was generally cost and size prohibitive to store the bits required in discrete transistor flip flop storage registers (though a few very early electronic calculators did use this method). Given that delay line technology had been used with success on computers (though the Univac I delay lines were very different than magnetostrictive delay lines), they were a low cost, relatively simple way to provide the small amount of storage required for an electronic calculator. A prime example of the use of magnetostrictive delay lines in a computer was the Packard Bell 250, a low-cost "personal" computer introduced in the early 1960's. The bit-serial nature of the delay line was ideal for a calculator, since a bit serial architecture is coincident with the most efficient way to make an electronic calculator, where raw speed is not a requirement, and minimizing the component count saves money. The serial nature of the delay line means that if a specific bit is needed, the logic must wait around for the bit to arrive at the end of the delay line. This slows down the operation of the device, but in the case of a calculator, where results are subject to human perception, 10s to 100's of milliseconds is well within the acceptable time for a calculation to occur. > I forget what the Dielh Combitron used but I know it used a two delay lines. One was for registers and the other was for lookup tables that loaded at turn on time from a metal tape ( as I recall ). The Diehl Combitron did use two separate delay lines, one for the registers(as well as learn-mode program storage) as mentioned, but the other one wasn't really for lookup tables, but instead stored the operating microcode that made the machine run. The microcode was indeed loaded from a punched metal tape at power-on time. The ingenious design of the Combitron was done by Dr. Stanley Frankel, a nuclear physicist who was deeply involved in the mathematical modeling that made the atom and hydrogen bombs possible. After the Manhattan project ended, he was involved in the design of quite a few computers and calculators. Notable computers that he designed were the Librascope-General Precision LGP-30, the aforementioned Packard Bell 250, and some design work on early General Electric computers. He also designed the Smith Corona/Marchant Cogito 240 (and follow-on Cogito 240SR) electronic calculator, as well as the Diehl Combitron. Many calculator companies used magnetostrictive delay line technology for storage in their earlier calculators, before the time that integrated circuits took over the storage duties. They included Friden(Singer) (all of their in-house designed machines used delay lines, e.g., 130, 132, 115x, 116x), Canon(which made machines for Monroe), Wyle Laboratories (WS-02 and Busicom 202, 207 and 2017), Olivetti (Programma 101 & follow-ons), Sony(early Sobax), Victor(1400-series), Monroe(EPIC 2000/3000, 820/820A), Diehl(which made machines for SCM and Victor), and Olympia. -Rick -- Rick Bensene The Old Calculator Museum http://oldcalculatormuseum.com

Oki 3305 disk drives

Hi all OK, following up on my own post here. >I have a couple of Oki 3305BU 1/3 height 5 1/4" drives. > >On startup the motor spins and the heads load, but the heads don't >move. Also, my BIOS tells me I have a drive failure. > >On taking them apart for a bit of a lube I noticed they have EPROM >8748s inside. Could this be the problem, EPROMs lost data? This would >be a first for me, I have EPROMs from the seventies which are still fine. I caused (I have people working for me who are really good at this) the 8748 to be removed from the one PCB. Reading it in my Expro gives me sort-of random results. Looks like some bits are high, some are low, and some float all over the place. No two reads return the same data, but some bytes are constant over two or three reads and other bytes are constant over two or three other reads. Is this the way an EPROM would fail? Seems reasonable to me. Anyway, I guess I'm SOL unless I can find a working drive. As far as I can tell these were used in the Heath / Zenith 170/170 luggables, also in the Morrow Pivot maybe. Tony would probably just rewrite the firmware. It's only 1024 bytes, how hard can it be? :-) Seriously, I am thinking of reading each byte say 100 times, averaging that, and then sticking the whole thing through a disassembler. But it seems a bit of a mammoth task. W

Looking to re-home some NeXT hardware

by bulk＠blit.ca

I have some NeXT hardware that I'm looking to re-home. Items include: 1 NeXT cube with an unknown expansion card 2 Monochrome monitors 2 NeXTStation "slab" workstations, non-functional Boxed NeXTStep installation media with manuals (may not be complete) 2 Mice, 3 keyboards, various cables, SCSI drives, odds and ends. (Picture at <https://drive.google.com/file/d/0B0Sme9n3mG2USjNJa3BaSVFJekk/view>; the fruit is not included.) I'm located in Toronto; preference will be given to anyone who is willing to come here and haul it away. I *may* be willing to ship it somewhere, but if so, you're paying for it and it can't cause me a lot of hassle. Everything is believed to work unless marked otherwise; however, it's been years since I powered up any of these so I can't promise anything. The monitors both worked when I last tried them. One had succumbed to the dimness problem but the other was still bright, if blurry. Presumably, you could swap CRTs and have one like-new NeXT monochrome monitor. One of the two slabs would get partway through its boot sequence before hanging so it might be easily fixable. The other one was stripped for parts before I got it. The Cube worked the last time I tried it. I did, however, try to add a second drive, which didn't work. This may have screwed up the SCSI termination.

Optical Mouse Pads

by bill.gunshannon＠hotmail.com

I am continuing the clean out of my vast collection of things I no longer have a need for. (Yes, everything you see me offer here was at one time used by me in real life!) I have three different model Optical Mouse Pads. NDE400306-003F NCW 402105-003 NDD 402105-003A Over time I have had optical mice from Sun3's, Sun4's, SGI's and even the old VisiOn mouse. I don't believe any of these to be from the Sun3 as it used bigger squares than these. Might not be any interest as it probably costs more to mail them (at least one at a time) than they are worth (unless someone needs one badly to complete a classic system!) So, anybody interested? What would you offer? (Expect about $7.00 for a Priority Mail Envelope which can hold more than one at a time.) bill

VT52 keyboard question

by cramcram＠gmail.com

Hi, The "2" key on my VT52 is very hard to use. You've gotta pound it and you might get 2 "2"s for your trouble. I assume that the keyboard switch is made of unobtanium (If you know of a substitute chime in) so I'm thinking of swapping it for the "COPY" key which I guess is useless unless you have the built-in thermal printer. 1. Do you simply pull the keyboard button off the switch or is there a trick involved? 2. Any other gotcha's? Thanks, Marc

help needed installing USB to Serial Cable for ADTPro

by starbase89＠gmail.com

Greetings! I am trying to connect my IIc to my laptop through ADTPro and am having trouble getting the FT232R adapter I bought from Retro Floppy. The host computer is an HP Elitebook running Windows 7 Pro 64-bit. When I first plugged in the cable, Windows tried and failed to find the device drivers. I downloaded the drivers from the manufacturer of the chip and and ran it. It told me installation was successful and device manager recognized that there was a USB serial port, but reported an Unknown Device and a Base System Device that didn't have drivers installed. I tried to use ADTPro but it didn't see a serial port. Has anyone run into this issue before? Thank you in advance! Joe Giliberti

But for the group...) Assuming there isn't a hardware issue like the null modem being plugged into the wrong DIN5 socket on the IIc, my guess is there's a bit-width issue with Java. First, some background: it sounds like you've been hacking around with (the location of) the RXTX serial library, which should not at all be necessary; it should be left where it is after unzipping the ADTPro distribution. Also, it's unusual for Windows not to recognize the FTDI-based chip in your UGREEN adapter; it should be automatically downloaded and installed. You should not need to install it manually. You should see the COM port populate in the Windows hardware manager when you plug it in (and the device driver is correctly installed). You said your Windows was version 7, 64-bit. Let's check Java. Go to a command line, and run 'java -version'. The build identifier will let us know if it's 32- or 64-bit. If it doesn't match your OS, that's the reason why ADTPro can't see the serial port (through RXTX). - David

As others said, we're not lawyers so ymmv but I would take it as the same as selling a used cd, dvd, software or books. The usual law is we can't copy it. So scanning it, if that company or company's intellectual property is still in existence they might care.

This is the LAST CALL for these. They'll be going to recycling if no-one claims them (aside from the Newer Computers) All stuff is in UK LN11 Postcode area. Prefer collection, but will ship small stuff at your *own risk and cost*. I will ship small items outside Europe but the large stuff is UK/EU only due to likely power supply restrictions and excess shipping costs. Unless otherwise explicitly stated, all items are **untested**. I will test computers on demand if needed. Cards and CPUs I can't really be bothered to. No returns, folks, ya gets what ya gets. There's a stack of pictures here: https://www.dropbox.com/sc/nt94k1zf0tn49wt/AACpoHnTm75yDhlFHQ6wd5WBa Identification of stuff is left to the reader. If you have any questions just drop me a line.

Flat Panel LCD sadly has several bugs stuck between the LCD and the backlight resulting in small black spots that look like 2-3 dead pixels Has original, working external speakers (have special powered plug!) - in similar need of light TLC *In Original box* (because frankly it was the only way to store it safely!) Probably have a matching White Keyboard and Mouse somewhere. Happy to ship to UK Buyer as itb s easy enough in the box =PowerMac G3/400 upgraded to G4/500/1M)= NOW FREE but will cost extra for shipping TESTED WORKING booted into Mac OS X 10.4.11 and tooled about.

AIX documentation

by jnc＠mercury.lcs.mit.edu

> From: Fred Cisin > be aware that legal advice here is often tainted by our own interests, > hence the fiction of "abandonware". Speak for yourself; my comments below are the legal position as best I know it, and not influenced in any direction. Of course, as are most people here, I am not a lawyer (although I've spent enough money on Intellectual Property lawyers over the years to send myself to law school, had I had the time, so I now know a little bit about the subject :-), and my perception is that the lack of knowledge on all our parts implicit in that is a far larger risk than any bias. > From: Warner Losh > Resell: sure. The copyright interest of the seller is extinguished when > you purchase them I don't think that's correct: any copyright rights held by any party are generally not, AFAIK, modified by sale of the material from a second party (i.e. not a rights holder), to a third (you). But that's immaterial, as long as one is only selling a copy which one purchased. As long as that copy was itself not produced in violation of a copyright, transfer to a fourth party (whoever you sell it to) is entirely legal. (Just like selling used books - which generally are in copyright - is legal.) You are (I'm pretty certain) not in any danger on copyright grounds, as long as you don't make any copies yourself. (What the situation is, if that copy _was_ produced in violation of a copyright, I am not sure of.) Restricted rights (such as a duty not to pass the material along) are probably not an issue, as that is entirely a civil contract between the issuer and the second party (above) who purchased them. If that party elects to sell the items _without_ making a second civil contract with the third party (you), those restrictions would not apply. For the second party's violation, the only recourse of the first party would be to sue the second party. Since the third party doesn't have a contract with anyone, there are no grounds for any claim against them. If there are trade secrets involved, I'm not 100% sure of the situation, since there are some protections for trade secrets in the law; but those mostly apply to deliberate theft or espionage. My suspicion is that if a third party gains access to trade secrets through negligence on the part of the second party - i.e. the second party giving/selling material containing trade secrets to a third party - the third party is clear to do what they want with the information. But maybe not, I just don't know enough about protection of trade secrets. The final area to be considered is theft. If the party from whom the documents were obtained did not rightfully own them (e.g. if they technically still belong to the first party, and they were merely on loan to the second party), then the third party (you) can't own them either, and so you (legally) can't sell them. Having said all that, it would probably cost more to ascertain their exact status (were they sold or loaned, etc) than they are worth (unless they are worth a goodly amount). But I also suspect that the rights holder(s) probably no longer care - but that's just a guess. Noel

MOVIE.BYU - progress

by rdawson16＠hotmail.com

Thanks group for the links to the source. These have passed thru many copies, and somehow have embedded control characters and such, but I am successful so far at the cleanup: I pull the source into a fortran knowledgeable editor, I am using "blocks" When the editor stops in the file, I drop into jedit, delete whatever is there, the invisible text and save; restart "blocks" and it parses further I should have this to compile in a few days. It outputs to the Tek terminal, for those guys working on that. Randy

Aquired PDP 11/23

by jnc＠mercury.lcs.mit.edu

> From: Devin Davison > This past week I managed to pick up a pdp 11/23. Nice system; the CPU has the MMU and FPP, you've got what's probably a 256KB memory card (an NS23M - documentation is available - depending on the chips, it can be 64KB or 256KB - if the former, let me know, I'll swap you a 256KB one), and I think the pair of quad cards are probably an RLV11. Not sure what that off-brand dual card is - maybe a ROM of some sort? I wonder what the card on top in the chassis is? It looks like it has way too many chips on it to be just a power supply board - but I can't figure out what it could be. Anyone know? Noel

Logic Analyser Advice

by robert.jarratt＠ntlworld.com

I finally managed to pick up a logic analyser for a price I could justify. It is a HP1630G and it comes with a number of pods. However the pods do not seem to have the actual wires/probes. Is there a separate part number for these that I should look for. There seem to be quite a few items like this: http://www.ebay.co.uk/itm/291753390848, are these likely to be suitable alternatives? Thanks Rob

Tektronix Terminal Emulation

by dj.taylor4＠comcast.net

I'm trying to return to the computing days of yesteryear when people hooked graphics terminals to VAXes. I don't have a Tektronix graphics terminal but I do have a MicroVax II and a laptop running Debian Linux. Up to now I've been using the laptop as a console device and connecting to the Vax using minicom. I thought that the laptop would be a natural as a Tektronix type terminal. On the MicroVax I have just started with PGPLOT and MIIPS, which are scientific plotting packages that run on Vaxes. I would like to use the laptop to emulate a Tek terminal connected to the Vax through a serial port, but there doesn't seem to be anything available to do that. Does anyone know of such a thing?

DEC DW11 information?

by derschjo＠gmail.com

Hi all - Anyone have any technical information (manuals, schematics, etc.) for the DEC DW11 UNIBUS->QBus interface? I'm curious to know what it's capable of and what the requirements are, especially on the QBus side of things. What kind of backplane is required? I assume it doesn't support 22-bit QBus devices given the age of the interface (and the complexity required to do so), but does it handle 18-bit devices, or only 16? I haven't found much technical information on it at all. Anyone have any details to share? Thanks, Josh

Aquired PDP 11/23

by lyokoboy0＠gmail.com

This past week I managed to pick up a pdp 11/23. Excited to finally have a qbus system, it is quite small compared to my 11/34. Attached are some pictures showing what i picked up. I am in the process of stress testing the power supply before turning it on. The whole machine was quite dirty and is being cleaned out as well. A whole corner of the machine corroded away, thankfully there is a metal shop around the corner with a press, I am going to replace the corroded sides. https://postimg.org/gallery/11t1el096/ --Devin

Tektronix Terminal Emulation

There are two things that come to mind as possibilities. First, if xterm isn't getting switched into Tek mode, who knows what you'll see displayed. To force it into Tek mode, start it with the -t option or in a vt100 xterm window do a ctrl-middle click and you'll get a menu where you can select "Switch to Tek Mode." The other possibility is that depending on setting, kermit might not be 8-bit clean. IIRC the Tek escape codes need the terminal line to be in 8-bit mode. When I'm connecting to a device speaking the Tek escape codes, I usually use cu instead, and it's generally worked pretty well for me. BLS

RT-11 5.x install tapes?

by j_hoppe＠t-online.de

Alan, thanks! - I saw that neither 5.5 nor 5.6 has no DD, but 5.0 -5.4G and 5.7 has. Didn't understand the reason. - Also DD.MAC in the 5.0 - 5.4 and 5.7 changes often. I tested tu58fs with oversized TU58 tape for 5.3 and 5.7, the number of blocks is always patched into into offset 0x2c, 0x2d in DD.SYS - I made a working DD.SYS with .macro DD, .link DD, .rename DD.SAV DD.SYS Do you know how to make DDX.SYS?

Vintage Computer stuff on EBAY.DE

by admin＠meiner.ch

Hello friends of vintage computing, As I need the space at home, I am parting from some of my vintage gear. They have all been listed on EBAY.DE. Among others, there are two PDP11 V03 systems, a number of CRT terminals and others. Have a look and see if you find something of interest. Head over to EBAY.DE and search for "PDP11 V03", and then see all my other actions. Just thought I'd let you know.. Martin

Borrowing a ADF scanner near Orangeburg SC next week?

by ian.finder＠gmail.com

I'm going on an archiving trip to preserve a deserving piece of computer history, but it turns out the scanner I'm borrowing is overweight and united will charge $100-200 to check it each way. Before I buy one off amazon, I wanted to see if anyone on the list was local and could let us borrow one Tuesday-Friday. Looking for a heavy duty, double sided ADF deal. Thanks, - Ian -- Ian Finder (206) 395-MIPS ian.finder at gmail.com

RT-11 5.x install tapes?

by j_hoppe＠t-online.de

Hi all, for work on TU58 emulator "tu58fs" I'd like to experiment with oversized tape images under RT-11 5.5, 5.6 and 5.7. The images I know about are the classiccmp collections, Earl Evans pointed me to the RT11DV50.ISO archive. However, in these images the TU58 driver files DD.MAC/DD.SYS/DDX.SYS are mostly missing. Strange, because they claim to be pristine. Somebody knows about original RT-11 V5 installation tape images? Thanks, Joerg

FW: More 8085a oddities

by witchy＠binarydinosaurs.co.uk

Hi folks, I didn't see the message at the bottom of this one arrive since I think I sent it JUST as the list software was being changed over. Gah, having just looked again I realise I've sent it from not the address I've subbed with. PEBCAK there :) Since then I discovered the -5V rail for the 4116s had dropped to -4.2V which was out of spec for both types of RAM on this box so on Chuck's suggestion I swapped the 560ohm resistor/zener combo that was powering this rail for a 79L05 regulator and the DRAMs now have all 3 voltages steady. No change in behaviour though. I'm baffled as to why the upper address bus doesn't blip once RESET goes high. HOLD is permanently pulled low so it's not that. Any suggestions? Cheers! -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection? ------ Forwarded Message From: Adrian Graham <witchy at binarydinosaurs.co.uk> Date: Sun, 26 Feb 2017 23:34:50 +0000 To: "Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Conversation: More 8085a oddities Subject: More 8085a oddities Hi folks, After a few days break I came back to my 8085a-powered phone system this weekend and it's decided to go on strike. By that I mean the processor locks up after only a few cycles so doesn't get as far as attempting to read anything, when it freezes the S0/S1/WR status lines are all high which shouldn't be possible since S0/S1 high should be 'Fetch' according to the manual, not WRITE. Vcc, RESET and clock are good and I can't see any other external signal which might hold the CPU. The PSU is good and putting out +5/+12/-12 as it should. CPU checks out in another 8085 system I forgot I had. Interestingly my analyser shows the upper half of the address bus doesn't change while the lower half manages a single transition, as does the ALE signal. From the CPU both halves of the address bus go directly to a 74LS373 each which both check out OK on a breadboard circuit I made up earlier. ROMs are all OK and the lines themselves back to the LS373 and CPU check out with little resistance. I'm stumped and can't help but think this is something stupid which I'm overlooking. Maybe more sleep will help. Cheers! -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection? ------ End of Forwarded Message

LMI Lambda - Software this time

by dseagrav＠lunar-tokyo.net

Great progress has been made in running the Lambda firmware and diagnostics. A way has been found to structure things such that the emulator is releasable without infringing on anyone?s copyrights. Now what we need is software tapes, specifically a Lisp distribution tape of any version. If anyone has any tapes in any condition, or knows someone who might have something, please ask them to consider imaging their tapes, or having them imaged. If you have images of anything that aren?t the images already on bitsavers, I would love to hear from you. Even partial or corrupt images are potentially useful.

Full immersion emulation

by charles.unix.pro＠gmail.com

Part of the iconic mainframe experience is the cold room sounds; for early Multics installations (and other systems) the sound of the Selectric operator's console. I/O Selectrics are rare, expensive and unreliable. If some good quality audio clips of a Selectric were available, it should be possible to jimmy up the console terminal emulator to make the sounds. So I am fishing for any existing audio clips with clean sounds, or someone with a Selectric that is willing to make some recordings, or a pointer to somewhere where all of this has been done already. -- Charles

Oki 3305 disk drives

by wrm＠dW.co.za

Hi all I have a couple of Oki 3305BU 1/3 height 5 1/4" drives. On startup the motor spins and the heads load, but the heads don't move. Also, my BIOS tells me I have a drive failure. On taking them apart for a bit of a lube I noticed they have EPROM 8748s inside. Could this be the problem, EPROMs lost data? This would be a first for me, I have EPROMs from the seventies which are still fine. Anybody familiar with these drives? Thanks W

by COURYHOUSE＠aol.com

have no idea... wife bought them at home depot they were not cheap but just twisted ino fixture and done. I am going to do dame in some of the rooms at SMECC museum too. I like a simple fix and this was! In a message dated 3/7/2017 12:43:24 P.M.

They do have to work thru ballasts and deal with starter issues that are no longer relevant, unless you remove and rewire the ballasts / starters out of the old fixtures. The things I've seen are the same form factor as a 4' dual tube dual 40 watt fixture with 110 in and light out. Pull and toss an old dual tube fixture and replace with new LED. But I've not seen the tube solution. I've got a couple of spots the tube thing would be desirable, but no source of such. If you do have a source I'd be interested. thanks Jim

we had tubes with LEDs in them... took old florescent tube out of fixture.. twisted in the thing with the LEDs in it that hacked wight into the lighting fixture and done!

MIPS I-IV instruction set standards

by aap＠papnet.eu

I'm wondering where the MIPS I-IV standards that are referenced everywhere are defined. I was able to actually find what seems to be the IV standard [1] but found no such thing for I-III. I didn't even find any bibliographic references to them. Did they only exist as printed books and nobody bothered to scan them? Or are they under copyright? Would be nice to have them accessible somewhere. [1] http://www.cs.cmu.edu/afs/cs/academic/class/15740-f97/public/doc/mips-isa.p…

3B2 stuff-maybe

by sales＠elecplus.com

I called the only place I know of that supported 3B2 stuff, which is Communications Hardware in TX. They recently had a change in technicians, and a lot of the older stuff they no longer support got culled, but they are willing to look for boards, drives, or whatever would help the collectors get their machines up and running again. I described the documentation set to them, and they will look for it. Any parts you want, send me a list, and they will hunt for me. Cindy Croxton

FTGH (you come get): VAXstation 100 terminals

by spectre＠floodgap.com

I picked these up as part of an estate liquidation, but I don't have a Unibus setup to run them off, and they are large and taking up space. They now need to be gone. The condition is unknown but they are intact. If you know what one is, you probably know how to hook it up and use it. If you don't, they are NOT VAXen -- they're more like overgrown graphics terminals that connect over Unibus. They are not like other VAXstations. Take as many as you like (greater Los Angeles area). However, units that are not spoken for, or haven't made other arrangements regarding, will go to the recycler this weekend. E-mail me offlist if you are interested. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- rm -rf /bin/laden ----------------------------------------------------------

Still Looking For AT&T 3B2 Internals Docs

by lists＠loomcom.com

Hello everyone, It's been about a year since I last asked around, so I figure it's time for me to put out another call for help. My AT&T 3B2 emulator sits unfinished due to lack of internals documentation. If you or anyone you know might have access to internals documents -- schematics, timing diagrams, etc. -- please let me know. These docs are very hard to find, and may never have been released by AT&T. Maybe you know a former AT&T engineer who managed to squirrel some away? I have many resources already, so I'm NOT looking for user manuals, SVR3 source code, or the IO Bus specification. These are pretty easily available online, and they've given me their all. Many thanks in advance, -Seth -- Seth Morabito web at loomcom.com

HP 2647A BASIC/AUTOPLOT47 and DEMO tape preservation

smecc would like a tape also! neat! In a message dated 3/7/2017 1:08:12 A.M. US Mountain Standard Time, cctalk at classiccmp.org writes: Dave, I am interested. I have an HP 2647 with two restored tape drives, and have been looking for this exact tape set. I have some "new" Athana tapes. Step 1 would be to copy them to a new Athana master tape.

Step 3 would be to transfer them to an archive format, but in essence it's already been done by the hpmuseum (in 5.25" 2647 disc format, LIF I presume?). But I don't have that rare disc unit and interface card to connect it to the 2647 (if I had, I could indeed recreate the tapes). That said, I first need to work on step 0, which is lots of practicing recovering DC100 tapes reliably: baking them, changing the belt, cleaning the guides...

Fluorescent lights (Was: Full immersion emulation)

Are they only available as an online option? > or (probably a better choice) with the ballast removed. Definitely - ballasts are such a pain. Actually, let me be more accurate: the ballasts in 4' (40W) lights (where they put the two bulbs in series) are a pain. The new ballasts for the 8' lights (a couple of decades back, in the US, regulations mandated a change) are actually a delight; you have to re-wire old fixtures a bit to install them (since the new ones no longer run the lights in series), but the upside is that 8' bulbs now either work - or don't. This is distinctly unlike the 4' ones, where bulb X will work when paired with bulb Y, but not when paired with bulb Z. (Because 40W bulbs are wired in series pairs, and as they age, their characteristics change.) I don't suppose there are ballasts for 40W bulbs that _don't_ wire them in series? Noel

Data General MTB Reference Sought

Does anyone have (a scan of) a manual that covers programming the MV-era MTB tape controller? I have a 1980 "Peripherals" manual (014-000632-01) from the "Programmer's Reference Series" which covers the MTA type, but it seems that the MTB behaves a bit differently and I am missing some information for my current project.

Anyone > have this information handy? Anyway, I've seen BA11-K boxes with several different kind of mounting slides. The tall, grey-coated ones are made by Chassis Trak, a division of General Devices of Indianapolis. The 4 I looked at, all idential looking (except for handedness), all had different numbers on the CT sticker, so I don't know what the model number is! This one says '060RH'. I've also seen BA11-K's with narrower (height-wise) slides, in some sort of bright metal finish. I don't know who made those. GD is still in business; I looked on their web site and found similar slides. I didn't order any because they were kind fairly pricy. BTW, does anyone know that they grey coating is? Is it some sort of phosphate plating, or perhaps some sort of early powder coat, or what? Mine are rusty, and I'd like to blast them and get them re-coated, but I can't figure out what that coating is. Noel

Rack-mounting a TU56

by ard.p850ug1＠gmail.com

I have been given an H960 rack :-). I intend to use it for my PDP8/e system (currently piled up, not connected), which consists of the : PDP8/e processor, Full of cards, memory extension, EAE, 32KW core, boot diode matrix ROM, RK8e, RD8e, RX8e, PC8e, etc. PC04 paper tape punch/reader (acutally, I converted a PC05, but that doesn't matter here) RK05 (well, there's an RK8e in the backplane and I have a spare RK05 so I might as well use it) RX01 TU56 (single drive version, ths is not a TU55 as some have suggested!). Various PSUs and step-down transformer for the TU56 and PC04 I think I have the right slide rails for the first 4 units too... Anyway, does anyone have experience of rack-mounting a TU56? It clearly doesn't go on slide rails, it bolts directly to the rack (hinge down the front panel for access). I have the manuals from Bitsavers, they imply there is some kind of spacer block that goes under the TU56. Does anyone know what that is exactly so I can attempt to make one if it is needed. -tony

I went looking in my BA11-K collection, and found a couple that do have the rotate - the part that bolts to the box has a huge 3/4 circular plate, and a metal strip that runs to the front of the box with a huge (~3") handle bar at the front, which releases it to turn. I have this bit set that the outer slides (the parts that bolt to the 19" rack) are the same for the rotating inners, and the non-rotating ones (as used on, e.g., the RK05 and the BA11-F). > I've also seen BA11-K's with narrower (height-wise) slides, in some > sort of bright metal finish.

PDP-11/34 rails?

Hi all -- I'm looking to rack up my PDP-11/34 so I can get it off my bench. I'd like to track down something similar to (if not exactly) the original rackmount rails (the ones that allow the chassis to pivot 90 degrees so you can deal with the backplane easily), but I'm not sure what the original part number or manufacturer was. Anyone have this information handy? Better yet, anyone have a spare set of rails handy? Thanks as always, Josh

Help needed for Unix anniversary in 2019

by wkt＠tuhs.org

Hi all, some of you may know me as the guy who runs the Unix Heritage Society and the archive of old Unix systems: https://minnie.tuhs.org/cgi-bin/mailman/listinfo/tuhs, http://www.tuhs.org and http://www.tuhs.org/Archive Mid-year 2019 is the 50th anniversary of the creation of Unix and I've been quietly agitating for something to be done to celebrate this. Up to now, there's been little response. The original Unix user's group, Usenix, will hold its Annual Technical Conference on the west coast of the US at this time, so it would make sense to do something in conjunction with this conference. Some suggestions: - a terminal room with a bunch of period terminals: ASR-33s, -37s, VT100s, VT102s, VT220s - these connected to emulated Unix systems either locally or via a terminal server and telnet to remotely emulated systems - some graphical terminals: Sun pizza boxes, a Blit would be great - if possible, some actual real PDP-11s, VAXen - emulated systems: V1 to V7 Unix, 32V, the BSDs etc. In fact there are plenty of Unix versions that we could run in emulated mode. - Unix of course was one of the systems used to implement the Arpanet protcols, so it would be interesting to get some of the real/emulated systems networked together - how about an emulated UUCP network with Usenet on top of it, and some mail/news clients on the emulated systems. - retro workshops/tutorials: how to edit with ed, using nroff, posting a Usenet article, dealing with bang paths. I'm proposing to gather a bunch of people to start the ball rolling on the technical/demonstration side. We'd need people: - with terminals, portable PDP-11s and VAXen, Sun boxen - prepared to set up emulated systems - who can help bring the networking (UUCP, Usenet, Arpanet) back to life - willing to write and run workshops that show off this old technology - to help set up terminal servers and all the RS-232 to telnet stuff Some of this we can start doing now, e.g. rebuild an emulated Arpanet, UUCP, Usenet, get emulated systems up, build front-end telnet interfaces. Is there anybody willing to sign up for this? I think once we have some momentum, we can tell the Usenix people and get some buy-in from them. Post back and/or e-mail me if you can help. Thanks, Warren

I just wanted to make sure that they weren't expecting something that might be a bit non-standard before I go trying to find modern replacements for a pair of failing disks. Assuming that an enormous modern(ish) drive is OK, are there any other gotchas involved in configuration and formatting? Obviously I don't need a partition bigger than a few tens of MB, but perhaps there are things to keep in mind when fitting a drive that's most likely to be getting on for a thousand times the capacity of the original. cheers Jules

Model 16 board set

by bill.gunshannon＠hotmail.com

I have a set of boards from an original Tandy Model 16 (long before the 6000) Worked when removed from a system with a dead CRT but has been sitting around for more than 10 years and I have no way to test them. Make an offer and let's see if we can keep them out of the landfill. Plan on probably $10 for Priority Mail. bill

Model II Technical Reference Manual

by bill.gunshannon＠hotmail.com

I have a Tandy Model II Technical Reference Manual available for sale. It is in one of those clunky brown Tandy binders so it will not fit in a Priority Mail Envelope so will need to go in a box. I figure $30 will cover it all nicely. Anybody interested? bill

Digital "we C.A.R.E."

by earl＠retrobits.com

Hi all. I'm hoping you can help me solve a minor mystery. I have a magnet with the DIGITAL logo, and underneath the logo, it says "we C.A.R.E.". I have no idea what that means, and Google searches have not helped. I'm assuming it's some sort of service or technical assistance program? Anyone heard of it? Thanks! - Earl

Binary keypad front panel

by wilson＠dbit.com

I made this as a joke, but also as a simple test device for a NatInst PCI-DIO-96 GPIO card I was writing a driver for: https://www.facebook.com/john.m.b.wilson/videos/10212562451077947/ It occurred to me that lots of old machines had binary front panels (switches and lights) and lots of machines had keypad front panels (octal or hex, with 7-segment LEDs), but I'd never seen a binary keypad front panel. Plus I wanted to experiment with Cherry MX keyswitches, and try out wasdkeyboards's custom keycaps (but they're $7/ea so I didn't want to try anything too big the first time). That plus two 74LS132s, four 74LS240s, and two 74LS273s, discrete stuff and cabling, and a PCI-DIO-96 that was $25 on eBay, and it works. "set dr dio96:" in the DOS and stand-alone versions of E11 V7.3 makes it (or anyone else's homemade doohicky) appear at 777570 as usual (or you can add "set dr r0" to get the R0-during-WAIT display like on a PDP-11/70 -- whatever your OS's NULJOB uses). I'd give Gerbers to anyone who cares but really it's just a dumb joke. Fun one though. John Wilson D Bit

Clock program for COSMAC Elf microcomputer with PIXIE graphics

by spacewar＠gmail.com

I've written a clock program to run on an unexpanded Elf with PIXIE graphics. It proved to be quite a challenge to fit it into 256 bytes, but I've now got it working, with two bytes of RAM to spare. There are 12-hour and 24-hour versions. I've released it under the GPL 3.0 license. The source code is in a github repository: https://github.com/brouhaha/elf-clock A text file containing instructions and hexadecimal object code is at: https://github.com/brouhaha/elf-clock/releases/download/v0.1/elf-clock-v0.1…

Cekit 8085 micro trainer

by jules.richardson99＠gmail.com

I picked up a Cekit 8085 microprocessor trainer last weekend, model MT-01. Google seems to be of no help - has anyone else here got one of these? There's nothing really specific that I wanted to know, but it's just odd that there seems to be no info out there at all about it. Some of the writing on the PCBs is in Spanish, and it says on the back that it was made by Cekit for EKI - but throwing that into the Google pot doesn't appear to be of any help. I'm not even sure how old it is. The CPU, I/O chip and some of the logic is dated 1983/84, but then there are a handful of Goldstar 74LSxx ICs with 90xx codes on them. It may be that Goldstar just didn't follow date code conventions, or it's quite possible that it really is that recent (and some of the ICs just came from much older stock). cheers Jules

Via Mike Ross, but contact Greg with any questions! ---------- Forwarded message ---------- From: "Greg Bebermeyer" <bebergee at gmail.com> Date: Feb 27, 2017 4:44 AM Subject: IBM System/32 - web response To: <mike at corestore.org> Cc: Hi Mike, Maybe this is no longer relevant since I can't tell from the web page how recent the post is... I am selling my house and in the back of the garage is a complete System/32 that was working when I stuck it there and covered it. Much other stuff is in front of it so I haven't seen it in a while. It's free for the taking to anyone willing to come to East Lansing, Michigan and pick it up. If you aren't interested then it'll just go to the scrappers because I need to get the place ready for inspection. The junk haulers should uncover it in a day or two at which point I could take pictures. I also have a PDP-11/60, if you know of anyone interested. Same deal - free, come pick it up. The 11/60 main box has been stored in a dry basement along with two RL01 disk drives (in free standing cabinets, not rack mounted) along with a box of flat interconnect cables. It was used in a cardiac unit to run heart monitors and has an extra card cage full of interface cards. Also there's 3 PDP-11/34s in a rack in the garage as well. All this stuff has to go in about a week to 10 days, unless arrangements/promises are made and kept. If you're interested in any of this stuff, or could refer me to someone who might be, I would love for this stuff to go to a good home. Yup, I started with FORTRAN and 80-column punch cards. Thanks.

Able board on eBay

by jnc＠mercury.lcs.mit.edu

> It's one part of a DMAX/16. Oooh, good catch. I hadn't looked carefully at those faint images, I was just looking at the brochure which had the separate images. > Not nearly as cool as an Enable :). Yes; the ENABLE was pretty clever: it used an MUD backplane as an EUB backplane, to hold the ENABLE and stock EUB memory cards; both the CPU _and_ DMA devices were on the incoming UNIBUS, and the ENABLE could tell whether a read-write cycle was from the CPU, or a DMA device (if you look at the UNIBUS spec, there's just enough to do that, even without being able to see NPG), and routed it through the appropriate mapping, depending.

Able board on eBay

by jnc＠mercury.lcs.mit.edu

So there was an odd board from Able up on eBay: http://www.ebay.com/itm/311809552775 Anyone know what it was? From the Able product summary it looked a bit like an Interlink/U or perhaps an Enable - although the detailed chip layout didn't look like the illustrations of either. Anyone know? Also, speaking of the Able ENABLE, I've recently discovered more about it, and now understand pretty much how it works. Noel

ViaNet?

by silent700＠gmail.com

I recently ran across a manual and disks for a PC networking product called ViaNet. It was marketed by Western Digital and targeted toward Arcnet, although it looks like it worked with Ethernet and other topologies. There isn't a lot of info out there about it but there are a few pieces in the old trade mags on Google Books. It was peer-to-peer between PCs, but there was also a UNIX host server product for it. Anyone ever worked with it? I scanned the manuals and posted them here: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/WesternDigital And the disk images are here: http://nocarrier.net/archive/floppy_images/PC/WesternDigital/ -j

Heathkit tube checker available

by jnc＠mercury.lcs.mit.edu

Hi, all, I have a Heathkit TC-3 tube checker, including manual and prints, available. Image here: http://ana-3.lcs.mit.edu/~jnc/tech/jpg/tmp/TubeChecker.jpg It has been modified with an after-market Coletronics panel with a bunch of additional tube bases. Condition is unknown; it probably hasn't been powered on in some years. It was in my wife's father's basement, so it was in a cool, dry space, at least. I know this isn't the best list for this, but I'm not on those lists; can people here who are, please forward it to those lists? Any interest, reply to me only, please - no need to litter the list!

huge thank you

by suea.pac＠gmail.com

Hi: Just a quick note to thank the cc forum for providing a platform to publicize our needs in an (nostalgic?) attempt to re-create a Data General Eclipse and Nova environment that we used for a number of years, over 40 years ago, in what I thought might well be a fruitless endeavor. Were it not for this forum, and in particular the generous assistance of Mr.Jay Jaeger of Wisconsin, the project would have never gotten off the ground. As it is, progress is now in store! Gratefully, Roger H. Anderson Endwell NY

Reading an ICT/ICL EDS8 (?) Disk Pack

by robert.jarratt＠ntlworld.com

I have been on the lookout for software for an emulator of MU5 that I am building. Manchester University has found a disk pack that is promisingly labelled. The disk pack has been provisionally identified as an ICL EDS8, apparently compatible with an IBM 2311 and with the mechanical assembly based on a CDC 9450. The University has asked The National Museum of Computing (TNMOC) is they have a drive that could read this disk pack, but it seems that although they have such a drive, they have no plans to restore it. Does anyone know of a working drive that might be able to read this pack? Regards Rob

DEC VT30-H and VTV30-J, was VSV11

by shadoooo＠gmail.com

Hello, given recent posts about Unibus graphic systems, I'm coming back with a request: was anyone some documentation about board sets VT30-H and VTV30-J? They should be graphic systems as well, the former Unibus, the latter Qbus. Definitely I think they aren't "regular" DEC products, maybe they were developed by third parties, as the PCB realization and style is far from DEC boards. I think they are really hard to find parts, would like to try to do something with it. Thanks Andrea

Cassette Interface Assistance

by brain＠jbrain.com

Analog, which is my nemesis, curses me again. I have a cute idea for a cassette port project for the Tandy line of computers (the ones with the cassette port). I have a Coco 3 on the bench, so I scoped the output line while doing 'csave "jim"'. The signal looks to be just under 1V PtP (0-1V on the scope), and rests at about .3V when not sending data. I have tried 6 different ways to boost the signal to 5V digital, to no avail, and so I ask humbly if someone with analog knowledge might be able to assist. I first tried to boost the signal with a transistor (with variations using a N channel FET as well). Arguably, that was foolhardy, and it did not work. My second attempt was based on this link that was shared with me: http://labs.rakettitiede.com/12kbps-simple-audio-data-transfer-for-avr/ The output from the Coco3 does not appear to be "loud" enough to work with this circuit. So, I finally decided a comparator solution would be required. First, I tried a design using a 741 op-amp, which failed miserably, but probably would have worked, but I tried to merge the design from the Coco1, and replace the LM339 in the Coco 1 design with the 741, and I feel I did not merge the designs well :-) I then tried using the comparator in an Atmel AVR, and had minimal success. By biasing one input via a variable resistor to around .8V, I was able to get a digital stream, but it did not look like the data stream of the cassette format. I then pried an LM339 out of my Coco1 and replicated the circuit int the Coco 1, as noted in the tech manual: Color Computer Technical Reference Manual (Tandy).pdf <http://www.colorcomputerarchive.com/coco/Documents/Manuals/Hardware/Color%2…> I was shocked that I had no success with that design at all. I assumed (wrongly, it appears) that the Coco cassette input circuit would read the output of it's output circuit. Beyond the possibility that my components are defective or I wired it up wrongly, I can only theorize that Tandy assumed that all tape recorders would AGC the output and then feed a 2V PtP signal back to the Coco (the Coco 1 circuit looks to bias the comparator at 1.05V (not sure about the feedback resistor's impact)) I can fiddle around with the AVR solution, which might work if I can smooth out the spikes and bias the comparator right, but it just bothers me that the Coco 1 circuit does not work, as I assumed I would at least have success by copying a working design.
