VAX & PDP-11 Stuff To Clean Out

by david＠thecoolbears.org

I have the following 5-1/4" Drives that I would like to get rid of. These have all been working at one time or another, but I have no idea what condition they are in now. Maxtor EXT 4330 Seagate ST4766N Hitachi DK516-12 Maxtor XT-8760E Maxtor XT-4170E I also have the following QBUS cards to part with. Module Number Part# Description Form QBUS Extender D M7504 DEQNA Ethernet D M8043 DLV11 4xSLU D M8043 DLV11 4xSLU D M7941 DRV11 16 Bit Parallel D M8186 KDF11 11/23 CPU D M8186 KDF11 11/23 CPU D M8189 KDJ11 11/73 CPU D M8192-YB KDJ11 11/73 CPU D M8192-YB KDJ11 11/73 CPU D M8047 MXV11 ROM/RAM D M7555 RQDX3 D M8029 RXV21 RX02 Controller D M7646 TQK50 Tape Controller D M8044-DB Memory 16K 32K?

I'd be interested in drive sleds for my BA123 or a spare power supply, also for the BA123 or I'm always interested in M68K/M6809 stuff. I would prefer local pickup near Livermore, CA. I don't believe that the drives are shippable. Please contact me directly at <david at thecoolbears.org>

VAX & PDP-11 Stuff To Clean Out

by david＠thecoolbears.org

Most of the items are spoken for but I still have the following: Caminton CMX1651 Memory M7606-AF KA630 CPU M7620-AA KA650 CPU M8067 Memory M7168 VCB02 Bit Map M7169 VCB02 Controller M7608-BP MS630BB 4-Meg Memory M7608-BP MS630BB 4-Meg Memory SCD-RQD11/EC ESDI Controller ...so, mainly the VAX stuff. Priority goes to local pickup. I've had all of these boards working at one time or another but I can't speak to their current status. David Coolbear david at thecoolbears.org

Qume Qumetrack 542 track seeking issue

by rescue＠hawkmountain.net

Been away for some time from the mailing lists.... getting back into my classic gear again.... I have two of these Qumetrack 542 drives. While testing my 360K drive collection (8 drives.... I must be slacking :-) ...), 2 worked, 4 had issue (resolved with a good head cleaning), and 2 (both of the Qumetrack 542 drives (I have two of them)) have mixed results. My testing is on a Tandy 2500SX/33 using the Tandy straight through cable and with the drives set do DS0. I seem to have no issue with Dunfield's testfdc (using testfdc/x a:) with these drives, doing SS and DD and getting 'pass' from testfdc. However, when I do a format a:, the drive will format through the 40 tracks, then instead of the heads returning to track 0 quickly, they do these small stepping 'bursts' and DOS times out saying failure..... it probably would have worked if DOS would wait 10 seconds or more for the drive to move to track 0. I've never seen behavior like this. I even tried an external power supply in case the Tandy one wasn't up to driving the full height floppy drive due to an aging marginal supply, but that didn't help anything. I've now also had one of them shut down the power supply (a shorted tantalum cap I'm sure). I've looked through the manual on the drive, I've tried the HM, HS, and no jumper setting for stepper motor power, same results in all cases. I'm trying too determine if these drives are good. I'm planning on using them in a Tandy Model III that is upgraded internally to a Model IV, but I feel these are basic drives and should work in DOS fine too. I hope someone has a clue, as I'm tapped out of them currently. Thanks, -- Curt

Repurposing cable for IBM Model M Keyboard

by robert.jarratt＠ntlworld.com

I need a keyboard cable for my VAXmate. This uses an SDL connector on one end and RJ11 on the other. Keyboard cables for the IBM Model M have SDL connectors at one end and a PS/2 connector at the other. I bought one of these cables with the intention of replacing the PS/2 connector with an RJ11. However, I now have a pang of conscience about hacking around with a perfectly good cable, particularly if they are uncommon. How common are these cables? Regards Rob

Looking for TEAC FD-55BV parts

by rescue＠hawkmountain.net

Need a faceplate and the eject control shaft (it is sheared off (the way I aquired it)) (I do have the eject lever).... I thought I had some floppy drive parts kicking around, but if I do, I can't find them (and chances are I don't have parts for that specific drive). Anyone have a dead drive, or parts from one kicking around ? Thanks, -- Curt

Modcomp Minicomputers Related - Preservation and Repair

by lyokoboy0＠gmail.com

Greeting. Its been a while since I have posted here. A while back I picked up a large Modcomp classic minicomputer. Recently the person i picked the computer up off of gave me a call to come and get many books and software, among much more hardware. I have picked up hundreds of 9 track tapes. The modcomp computer mainly ran the real time os MAX, however i also found many tapes for a unix variant for the machine, that supported real time operation as well. I am trying to preserve things as best i can, I am set to pick up 3 more machines, and among the tapes and documentation, Space is running out fast. I am curious if any of this documentation has been archived already, if not, i can get to scanning it in my free time. I have documentation on everything. The hardware, the software, os code, everything. The tapes are another issue all together. They were stored in probably the worst possible place, in a area of extreme heat and humidity. Some are musty, others look like new. I do not own a 9 track drive, i was thinking it would be possible to get a 9 track drive with a scsi interface attached to a more modern Linux system to dump the tapes to images. If anyone here has suggestions on how to read off the tapes or where to find a drive, it would be most helpful. As a last resort, I have a 9 track drive that is attached to my pdp 11/34, however i have not gotten that system into working order yet either, and am unsure of if the drive is working yet. I was also given an old emulator for the system,m written for linux. I have not gotten the software to work yet. I need to be sure the software is not still a licenced product and that the company is gone before i post it. Perhaps someone here can find out why its not working. On a modern debian system, it attempts to run and just exits, without any info as to whats wrong. Any help or suggestions on how to best preserve the documentation and software is most appreciated. I am undecided on what to do with the hardware yet. The hardware is fascinating, and there is a bunch of it, however it is quite large and is taking up a large portion of space. The hope is to at least get one running to test out and see if i decide to keep a system after that. --Devin D

TRS-80 Model III stopped responding

by rescue＠hawkmountain.net

I haven't dug into this one yet, but I did get it booted in trsdos, and the letter I on the keyboard wasn't working. I shut it off, disconnected and removed the keyboard. I desoldered and removed the APLS switch, opened it up, cleaned up the carbon pad and the contacts below it, reassembled it, tested it with my DVM, all good to go. I soldered it back into the keyboard, put the keyboard back, powered on the system.... I get CRT glow, system reset button will cause the floppy drive to seek, but nothing on the screen, and pressing return after inserting TRSDOS does not boot the drive (i.e. testing for a working core system with no display....). I do need to test the power supplies and make sure I have not lost a power rail on one of the two supplies. I presume the one I need to check is the one on the backside of the cpu board, as the one on the side of the drive 'cage' powers the drives and the drive controller board, and on power up and reset, the drives are motor on and tracking, so I think that supply is at least providing +5/+12V. Seems odd that putting the keyboard back in resulted in a non working system. I unplugged it, same behavior with no keyboard plugged in. I did not connect the kb connector off by one pin or one row.... so as best as I can tall, Murphy has struck, and it isn't 'operator error' :-). Any tips from Model III experts welcome. -- Curt

Looking for DEC RA80 (or RM80, R80) service manual (EK-ORA80-SV or similar)

by derschjo＠gmail.com

Hi all -- I have an R80 drive in my VAX-11/730 cabinet that I'm trying to get running. Symptoms are: most of the time when the Run/Load switch is depressed, the drive will begin spinning up for 1-2 seconds (sometimes as long as 3-4 seconds) and then stop, faulting with error code 01 ("Spindle Timeout Error"). Every now and again it will spin up and go ready -- the other night it ran for several hours, long enough for me to get a dump of the disk with no read errors (*). I've checked the usual -- the motor and the spindle spin freely and the belt is good and tight. Connectors have been cleaned and reseated, as have socketed ICs. Power supply voltages are OK. The motor start cap tests fine. I'm getting pulses from the optical spindle sensor. I suspected that the brake might have been slowing things down during spin-up as it was a bit noisy (due to some light corrosion), but the spin-up error persists even with it entirely removed. I haven't been able to find the actual service manual for the R80 (or the very closely related RA80 and RM80 drives). Anyone have a copy stashed somewhere? Anyone have any debugging advice? Thanks as always, Josh (*) The drive contained a 4.3BSD system used to run a bbs and uucp relay, "Darkstar 730" out of Beaverton, OR. Looks like it was last run in the early 1990s. Now I just need to track down the owner :).

Floppy drive (DSDD) DOS compatability woes (are these drives ok?)

by rescue＠hawkmountain.net

Been away for some time from the mailing lists.... getting back into my classic gear again.... I have two of these Qumetrack 542 drives. While testing my 360K drive collection (8 drives....

I seem to have no issue with Dunfield's testfdc (using testfdc/x a:) with these drives, doing SS and DD and getting 'pass' from testfdc. I can also use his imagedisk program, go to the alignment section, and I can track the drive properly up an down the disk.... it is just DOS that can't seem to do it. However, when I do a format a:, the drive will format through the 40 tracks, then instead of the heads returning to track 0 quickly, they do these small stepping 'bursts' and DOS times out saying failure..... it probably would have worked if DOS would wait 10 seconds or more for the drive to move to track 0.

George Schmidt, Distinguished Lectures, January 16, 2020

by mark.tapley＠swri.org

All, Southwest Research Institute will be hosting a talk in San Antonio, (Texas, USA) by one of the engineers involved in the Apollo navigation effort, George T. Schmidt. I understand he is aware of and very interested in the Apollo Guidance Computer work done by some of the folks on this list and others, but anyone who has not had a chance to talk to him might well be interested in attending, and would certainly be welcome. The abstract and title for the talk are below, along with the URL for the IEEE distinguished lecturer website (which doesn?t say any more than I have copied below). Anyone interested in attending, let me know and I?ll forward more details as I learn them. I expect the lecture will be around noon on Jan. 16 at SwRI, with a repeat at St. Mary?s University in the evening. Inside Apollo: Heroes, Rules and Lessons Learned in the Guidance, Navigation, and Control (GNC) System Development<https://urldefense.proofpoint.com/v2/url?u=https-3A__nam12.safelinks.protec…> This Abstract was written in March 2019 which is halfway between the 50th Anniversaries of Apollo 8 (Dec 1968) and Apollo 11 (July 1969). Those 2 flights were among the greatest explorations of mankind. In 8, astronauts deliberately put themselves in orbit around the moon expecting the rocket engine to later fire and bring them home to Earth. In 11, it was mankind?s first visit to the moon and Tranquility Base. Movies, books, articles, and documentaries have covered the space race. The author will give his thoughts based on 10 years inside the GNC program design, many hours in the Spacecraft Control room at Cape Kennedy monitoring GNC performance through liftoff, and then providing real-time mission support to NASA from MIT in Cambridge, MA. that abstract appears on this website: http://ieee-aess.org/education/distinguished-lecturer-and-tutorial-program#… - Mark 210-522-6025 office 210-379-4635 cell

Paleontological data fossilized on IBM 8" floppies

On 11/3/19 1:47 PM, Lyle Bickley wrote: > Antoine, > > It's not too difficult to read most "standard" 8" floppies (DEC RX02's being > the exception). The board below deals with both signal routing between 8" and > standard PC floppy interfaces and the "TG43" signal required by most 8" drives: I believe that the TG43 signal (if required; some drives generate it internally) is only used for writing (reduced write current). You can probably get by just fine if you've got the connectors handy by wiring up your own cable. Micro Solutions, back in the day sold a small adapter PCB with a 34-conductor PCB edge connector and a 50 conductor header for connection to a SA-800 style cable. This assumes that your 8" drive follows the SA-800 pinout convention. Some early drives (e.g. Calcomp, (IBM) do not. Same for the power connections. Many use the Amp (now TE) Mate-N-Lok connector PIN 1-380999-0, but by no means all. AC connections, if needed are subject to the usual 50/60 Hz and line voltage considerations. I use older open-frame linear power supplies, but the +24V/+5V requirement is a lot easier to satisfy today, since inexpensive multi-amp SMPSUs are available (generally less than $15). Even dual- and triple- output PSUs are available for around $20 that should supply more than enough current. Hope this helps, Chuck

Original DEC logo in PostScript

50 yrs. ago today

by c.murray.mccullough＠gmail.com

The first inter-computer communication happened 50 years ago today. L. Kleinrock part of that historic moment, said, and I paraphrase here, ARPANET was the instrument that was to enable computers to talk to each other remotely. He sent ?LO? because the system crashed(how surprising was that!) This was the precursor to the inter-net, moving from the intra-net. Happy computing all!

If they had a proper release to work out the manufacturing issues they would have been a lot more successful I think. Nevertheless, any system in the wild you come across should work just as well as any other vintage machine by this time. It's my favorite machine pre-Amiga/ST/IIgs/Mac.

Coleco & Atari

Coleco ADAM, my favourite, and Atari 600XL, not so much. I still have my ADAM. No not why. But isn?t this why we all belong to classiccomp. And $600. How quaint!

Philips mini computers

by nico＠farumdata.dk

Hi all, Back in the 70's and 80's Philips had a quite popular series of mini computers called P800, which also branched out to the PTS series and possibly other. Could I be lucky to find other list members interested in these products? I know of a few, but there surely must be others. I'm trying to collect what is left of the documentation. 73, Nico

VCF PNW: 2nd call for Exhibits, Speakers and Volunteers

by mbbrutman＠brutman.com

Just a friendly reminder ... VCF PNW 2020 will be on March 21st and 22nd at Living Computers:Museum+Labs in Seattle, Washington. We are looking for exhibits, speakers and volunteers. Presenting an exhibit or speaking at the event takes a little time but it is not difficult. And the reward is that you get to share something that you are passionate about with like-minded people, usually over 1000 of them. Exhibits range from small homebrew machines all the way up to high dollar bigger-iron. (I didn't say big iron because we have not had anybody move anything in with a forklift yet.) Pictures from previous years and details on what to expect can be found at http://vcfed.org/vcf-pnw . Volunteering is pretty easy too; we usually just need a few extra hands to do setup, teardown, and some minor tasks. In between you get to enjoy the museum and the event. If you have special skills we'll put those to use too. If you are thinking of traveling from outside of the region there is plenty to do in Seattle while you are here. Local attractions include the Connections Museum, the Pacific Science Center, MoPOP, the Boeing factory tour, Mr. Rainier, etc. Victoria, British Columbia is also a short distance away. See a more complete list at https://goo.gl/3emMWH . Five months seems to be the distant future but we all know how quickly it will pass. If you are mildly curious or have a question don't be shy - I'm happy to explain the event in more detail. Regards, Mike mbbrutman at brutman.com or michael at vcfed.org

Anyone have a firmware dump for Teleray Series 10 terminals?

by ethan.dicks＠gmail.com

Hi, All, I was recently at the CompuServe 50th Anniversary event which included a tour of our old building at 5000 Arlington Center Blvd, where I worked in 2001-2002. The old data center is still in operation, being rented out by Expedient as a cloud hosting and co-location facility. One of the highlights of the tour is an old Teleray 10T they found when they moved in 9 years ago. They have it cleaned up and on display in their conference room. I did a little digging and quickly found the docs on Bitsavers (thanks as always, Al). What struck me was the appearance of the mainboard. I went up into my attic, and wouldn't you know, I _have_ one, labelled "Model 10C" - same board but (formerly) with special feature firmware to be a 10C. What I don't have is ROMs in the ROM sockets. :-( It's five ;places for standard 2708 EPROMs. From the memory map and some of the photos in the docs, not every model had ROM in "Position 5". It looks like all did have 4 EPROMs installed. I have blanks and I have a burner. What's not up on Bitsavers is the 10T or 10C firmware. Does anyone have anything like that? It looks like the keyboard is both easy and not easy to remanufacture. It's a raw matrix, attached via fat round cable and DB25. The Keyboard includes a 74154 to decode 4 bits to 16 lines and the returns are via 8 lines. On the Terminal side, the 4 bits map to the 6502's A0-A3 and the return lines map to D0-D7 (it appears at $0000-$000F in the memory map). 91 keys, 1 IC and a lot of diodes would implement a keyboard, as would an AVR microcontroller sitting on the 12 row/column lines, translating to/from a modern keyboard. The video appears to be standard 15.575KHz 1.0-2.5V mono video plus H. Sync and V. Sync. routed off the board via the power supply connector (+5V @ 3A, +/-12V @ 0.4A and a smattering of -5V for the 2708s). So the only thing I would really need is copies of 4 or 5 EPROMs and I think I could get this working with a replacement display and reimplemented keyboard. Anyone happen to have the firmware? Thanks, -ethan

Vigra MMI-210 (VME DSP/audio card) documentation?

by cmhanson＠eschatologist.net

I just acquired a Vigra MMI-210 VME DSP/audio card that I?d like to get working. Does anyone happen to have manuals or know where I could find them? The Wayback Machine at the Internet Archive provides some programming information <https://web.archive.org/web/19970811215245/http://vigra.com/products/vme-au…> so if I can configure the card, I can make it do things. Unfortunately I have yet to find an installation guide. Since it?s a VME card, it has plenty of jumpers that will need to be properly set before it?ll actually work. Anyone have a source for more information, or another place to dig for it? -- Chris

IBM 129 keypunch: How to remove the complete mechanics unit?

by p.gebhardt＠ymail.com

Hello all, I may get a 129 IBM keypuncher soon and was wondering, if for transportation- and weight-related reasons, the punch&read mechanics can be carefully removed with the cables from the rest of the sytem? >From the IBM documents, it seems that after removing the top cover from the table, the mechanics connected to two holders (one one each end) could be separated from the table by removing two screws and two bolts (one of each on every side) and deconnecting all cables down in the electronics cabinet. See for instance: UvA Computermuseum UvA Computermuseum Did anybody make any experiences with this? I am grateful for any suggestions and/or recommendations.

Sun Ultra 1 PROM update to OBP 3.11.1 or better

by jacob.ritorto＠gmail.com

Hi, My pal Dave just gave me a very nice original Ultra 1 Creator! Found a nice 10000K 146GB disk and 1GB genuine X7004 Sun RAM from good old MemoryX and this store I'd never used before called DiscTech (great ecomm site and decent prices afaict), so this baby's shaping up to be a fantastic and affordable rescue! Alas, it seems some corporate best practices aficionado from the company that was entrusted with the care and feeding of Sun has unilaterally and unceremoniously "lost" all the old patch clusters for these machines. Anyone still have them? The particular one I need is the patch SUNWflell >from anytime after late 1997. This will allow her OpenBoot to play nice with 64-bit operating systems like Solaris and the Illumos-based Tribblix, OpenSXCE, etc, which I'm thinking will be extremely cool to see running on a 25 year old machine! thx much. jake

VT420 drawings

by mattislind＠gmail.com

I got heaps of documentation from an ex-DEC field service engineer. Among them there were a VT420 print set. I didn't see any schematics for the VT420 on bitsavers so even though this one looks a bit strange it is better than nothing. http://storage.datormuseum.se/u/96935524/Datormusuem/DEC/VT420-engineering-… /Mattis

DEC documentation

by mattislind＠gmail.com

I have updated my inventory of DEC documentation with the latest arrivals >from Gunnar, the ex-DEC FS tech. Those were mostly binders of software documentation and handbooks. If there are a document that you would like to have scanned I will do my best to help out. But please do me a favour to check if they are not online already >from the regular sources. http://forum.datormuseum.se/category/35A7E09F-5154-49F1-BE57-9F9E3D923327.h… I can only scan documents up to ledger size. Larger documents, like some of the old schematics, need help from a professional scanning service, which unfortunately cost money. I cannot scan books, either. I will continuously update the inventory as I go through all the documentation. There are likely to be errors in the inventory. Typing on the phone is a pain. If you find errors please let me know. /Mattis

plated wire memory

by dkelvey＠hotmail.com

I was just listening to a video on the Voyager space craft. It used an interesting type of memory, called magnetic wire memory. There is only a little bit of information of it on the web. It is clever in that has a non-destructive read. I just wondered if any one else was familiar with this type of memory. Dwight

plated wire memory

by tpisek＠pobox.com

I worked at Univac Defense Systems in the early 70's. The launch control computer for the Minuteman was made by Univac. It had plated wire memory. I remember when the failure analysis group had to analyze a module that failed in the field. The module was locked in a safe and someone had to boost their clearance level to work on it. In plant 1, in Saint Paul, MN near the Mississippi River, there was a thin film memory production facility. It produced the memory used in the S3A submarine hunter (an/ayk-10 if I remember correctly). The bit planes were made from etched glass that had metal sputtered onto it, with tons of tiny holes for the word wires. The bit planes were stacked and the word wires were threaded through the tiny holes perpendicular to the planes. Because I sometimes worked out of plant 1, I had to take safety training for hydrofluoric acid which was used to etch the glass. Nasty stuff.

Fwd: For auction: Amiga 3000

by sellam.ismail＠gmail.com

This is an Amiga 3000 in excellent condition, both functionally and physically. Other than the very slight yellowing of the front face and one barely visible scrape, it is almost perfect. It is extremely clean inside as well. The on-board battery has not yet been removed but it should be soon as it has begun to outgas and affect the surrounding components. I cleaned up the minimal oxidation it had caused on some of the various components local to it. The capacitors have no visible age-related issues. The system boots up into Amiga WorkBench 3.1 and has numerous applications and drivers installed. Video output is from the GVP EGS (works with SVGA monitor) board, which plugs into the on-board video port (via external connector cable).

Free to a good home: Honeywell/Bull DPS-6 workstation / server (Seattle, WA)

by derschjo＠gmail.com

Hi all -- I picked this DPS-6 up over the summer and it's just taking up space (quite a bit of space) in the corner of my basement. This is a custom 16-bit, bitsliced, microcoded CPU from the early 80s with (I believe) 8mb of memory, and ethernet. It would originally have run a version of GCOS. It's about the size of a large-ish minifridge, but a bit deeper. It's also quite heavy! It's a neat machine, but it's very obscure and unfortunately incomplete (it is missing both mass storage and storage controllers). Otherwise, it is complete and in good condition (albeit a bit dirty). So you can see why you'd really want to have it in your collection . If anyone's up for a project, drop me a line. Local pick up in Seattle, WA. Thanks, Josh

cctalk Digest, Vol 61, Issue 17

by iain＠csp-partnership.co.uk

Paul - I had a quick look at PLATO. I dont think it was like that. In this game when you set a movement direction and velocity you moved through the universe in that direction ?forever?. There was not concept of ?moves? or ?turns?, it was very dynamic. Spasim looks much closer - but was that ?vector graphics?? The game I was using was just 24 x 80 characters. For the year and the WYSE terminals (etc) it was great. > > I wonder if this is a port of the PLATO game by the same name, which goes back to 1976 or so. PLATO had lots of multi-user games with various levels of graphics sophistication. Space war games included "conquest", "empire", and "spasim" -- that last actually had 3d graphics, which was quite a stretch for 1977. Then there was "airfight" (the inspiration for Microsoft Flight Simulator) as well as a boatload of "dungeon & dragons" games. > > paul > ------------------------------ > > Was it in use at Berkeley? I might have it stashed away in some of my > BSD-related tapes. > Chuck, I am Scottish, I have never been to Berkeley! I just cant remember the history. I remember playing the game with a bunch of post-graduates. I was either a post-grad or perhaps an early lecturer in the Uni. That places it square in the mid-80s. I did spend most of my time researching. The games would have appeared on tapes from other places?.. I am hunting around amongst the post-grads to see if any of them can tell me where it came from. I knew the game as ?search? in that that is what you typed in to start it. To keep the undergrads out if it we had to put both passwords and time-locks in the code?. Iain > --Chuck

looking for a program - last gasp questions

by iain＠csp-partnership.co.uk

Not star-trek.... I am trying to track down the source of a unix game ..... Years and years ago - 1980s - I was in the Computing Science Department at Strathclyde Uni.? and we had a bunch of BSD4 systems running on VAXen. I have memory of - but have never located - a curses based 24 x 80 display - multi-user "space-war" game that allowed you to navigate around a 3D universe with the 24 x 80 giving you a full screen view of the universe.. In the game you could * hunt the universe for aliens (like "shankers" I cant remember the others), * other players - you saw them as they saw you you could also team up with other players to have more firepower and call for help using a 1-line on screen chat/broadcast system, there were planet(s) scattered about - that you could hide behind. The students and I modified the program with some "special features".? I cant remember if the name of program was changed too ;-( Anyway we knew the game as "search", it was written in C - it was a good test of serial output capability of the VAXen - it was also a great way to teach students about the VI keys - since hjkl worked as expected for movement (at least that was out excuse to the prof when caught playing the game during the day). From my poor description can anybody tie down what I am looking for? Appreciated Iain

Strange DEC stuff.

by mattislind＠gmail.com

An ex-DEC engineer offloaded some strange stuff that was going to the skip. I just thought I could have a look. But what is it? There is two backplanes marked KA14 and BE14. I thought it was the PDP-14, but I am not sure really. https://i.imgur.com/86tcLFz.jpg https://i.imgur.com/BWiCz8l.jpg I came together with a similar sized PSU. Then there was a strange DEC workshop built paper tape reader. The reader mechanics looks similar to PC04 and PC05 but is smaller. The wheel is smaller and the stepper motor is smaller as well. Are these parts from some other DEC reader they cobbled together at DEC for inhouse duty. https://i.imgur.com/0zv55pP.jpg https://i.imgur.com/rE423Hi.jpg https://i.imgur.com/8th1y3Z.jpg https://i.imgur.com/VKoH2LX.jpg Any clues?

I apparently have Spacewar for Unix?

by dseagrav＠lunar-tokyo.net

While dumping lispm tapes, I found one with a label saying "Read it into DRAL" (may be "DRAC"?) "and sent a message to cap's bboard saying where it can be found. -Bob?. There was another paper label that had fallen off. What I think is the label in question was later found in the bottom of the box, a strip of masking tape saying ?SPACEWAR FOR VAX (Unix?)?. The contents are a 136KB tar archive containing source to a program called ?orbit?, all files are dated August 22nd, 1983. The README file follows: ?? To install orbit: 1. Do a 'make all'. 2. Make sure the directories on the path /usr/games/lib/orbit/* all exist and are writable by you (except /usr, of course). 3. Do a 'make install'. This should work with no changes on Berkeley 4.2, unless the structure for the console keyboard buffer has been changed. The crock that reads the up-down codes here should be changed to use the real ROM-table hooks, anyway. Unfortunately, all that nice stuff is in protected memory. Enjoy! - Bob Bane (bane.umcp-cs at UDel-Relay) ?? Does anyone know what this is? The (gzipped) tar file is at https://www.bogodyne.com/wp-content/uploads/2019/10/orbit.tar.gz <https://www.bogodyne.com/wp-content/uploads/2019/10/orbit.tar.gz>

LISP implementations on small machines

by sieler＠allegro.com

David...where did you use Lisp on a B6700? Bill Gord and I wrote the first INTERLISP interpreter for the B6700 back around 1974-1975, on a DARPA contract, at UCSD. (At the start, it was to implement BBNLISP, but the name changed during the project :) DARPA found that researchers using INTERLISP (or others) on Dec PDP10s (and similar) were hampered by the limited address space (256K virtual memory). The B6700 offered a significantly larger address space (and many other features, of course :) (I know our LISP got distributed to other Burroughs sites in those days, just like our STARTREK and Bob Jardine's SOLAR.) Danny Bobrow (with Xerox PARC at the time) came and helped us get started. I met Warren Teitelman ... he had no idea that the cover of the INTERLISP manual was an homage to his last name. (See: http://bitsavers.org/pdf/xerox/interlisp/Interlisp_Reference_Manual_Oct_197… ) We got our system up and running, including DWIM and other packages, and were told ... oops, DEC figured out how to expand the amount of virtual memory on the PDP-10, so we don't need to buy Burroughs mainframes now! Our INTERLISP was a full interpreter, and also had a compiler to LISP p-code, which might have inspired UCSD Pascal's p-code (Ken Bowles was our boss). I believe I have the source, in Burroughs ALGOL. As a side bonus, I got to interact with Danny, and people from PARC and BBN as we were watching other UCSD Computer Center people put the B6700 on the ARPANET. (I think we were something like the 25th computer.) Stan Sieler

The PDP-6 and KA10 (basically a re-implementation of the PDP-6 architecture) both had cheapo versions where addresses 0-15 were in main memory, but also had an option for real registers, e.g. in the PDP-6: "The Type 162 Fast Memory Module contains 16 words with a 0.4 usecond cycle." The KA10 has a similar "fast memory option". Noel

DIBOL manual

> From: Chuck Guzis > One could argue that it's just as similar to FORTRAN (cf. computed GOTO > and logical IF statements). It probably worth pointing out that I never used COBOL, and have little knowledge of it. So when one reads "it is vaguely reminiscent of COBOL, as it has a 'Data Division' and a 'Procedure Division'", I must have copied that all from some source I found, because I don't know what the 'Data Division' and a 'Procedure Division' are (although I can guess from the names). > Where it differs mainly from FORTRAN of the times is a facility for > record layout I seem to recall that COBOL was the first language with support for structures? If DIBOL has support for them too, which would be another similarity between the two. Noel

Kennett Classic Opens This Friday

by billdegnan＠gmail.com

Hi - I was not going to write about this here until I was pretty sure we were on track, but it looks like we are go to open our new vintage computer gallery and hobby shop this Friday. If you're local to the Philadelphia/Baltimore area, look us up and better yet, pop in for a visit. Our first feature exhibit will be a Commodore History, but we also have a lot from the 1950's through the 70's on display to tell some of the lesser-known tales before the microcomputer era. The idea here is to bring vintage computing to the local community via something that they can identify with (i.e. Commodore) but also have historical depth for those of us who have a passion for the history of computing. For more details our new URL is. https://www.kennettclassic.com/ Thanks Bill vintagecomputer.net kennettclassic.com

Eyring PDOS - paging Camiel Vanderhoeven

by mattislind＠gmail.com

I have a odd TMS9900 machine with floppy drives that would be interesting to get an operating system runnig on. The Eyring institute PDOS looks interesting and I have found a page describing it. https://www.vaxbarn.com/index.php/other-bits/105%20-pdos Unfortunately none of the download links works. I sent a few mails to Camiel but it seems like they might have ended up in the garbage folder so I am trying this public mail instead and hope that it gets through! I really appreciate if the links could be fixed so that I could download a copy. And source code for the boot ROM would be nice. Or is there someone else that have a copy of the manuals and the binaries? Thanks in advance! /Mattis

Wanted: 360k floppy mechs

by technoid6502＠gmail.com

I am in the middle of refurbishing two drive controllers, a Percom At88 with doubler board, and a Percom At-88SPD. Neither has mechs and my search for them has been frustrating. The mechs are like hens teeth online, and when I find them they are insanely expensive. I know there's gotta be a pile of them out there just rusting away. I'd like to give as many as four a good home. Mechs I can use are, in order of desireability: 5.25" 40 track, double -sided, 80-track double-sided, 40 track single-sided. 3.5" mechs (preferably with adapters for 5.25" mounting, have got to have jumpers for drive number selection. Most 1.44's will work on these controllers as 720k drives if the right media is used, or, better, if the drive has jumpers to force the density select. I hate to bother with such a petty thing, but I could sure use some help getting these things running. They are nice drives. I repaired one already, and got it driving a broken MDD210, the only mech I have, but that is so flaky it is of no use other than to let me know my repairs have got the controller working again. Best, Jeff

General Automation SPC 16 on eBay

by bobalan＠sbcglobal.net

There's a cheap General Automation SPC 16/45 on eBay that someone needs to get. It's for pickup only in Royal Oak, MI otherwise I would go for it. Includes a disk drive. Looks like it needs to be gone in a week.

Mystery chip SCM44506L

by wrm＠dW.co.za

> >Very likely a semi custom or custom memory device, due to the prefix. Armed with that and the fact that pin 1 connects to the leadframe I figured maybe it's something like the 6830 Mikbug prom -- 0V on 1, 5V on 12, data on the left, address on the right. Tried reading it like that (for all 16 combinations of chip selects) but 0xFF throughout. So I popped the lid, stuck it under a microscope. The chip says "MCM6816" which is in fact a 1k ROM. Anyone have more information on the 6816 ROM? Thanks W

DEC Rainbow Univation Docs / Software

by imp＠bsdimp.com

This is a bit of a hail mary... I recently won a Univation Intenral Hard Disk System for the DEC Rainbow 100 card, memory and drive. But it came with the wrong docs and no diskettes. Any chance that anybody has anything in this area squirreled away somewhere? Warner

"Older HP equipment of little value"

by sales＠elecplus.com

There are 28 pallets of older HP and Cisco equipment being sold by a broker in Germany. The equipment is located in Hungary. If you can handle taking in a huge amount, and you are in Europe, please contact me. This is not a pick and choose. It is a "take all" situation and will require payment. I do not know the requested value for this lot. I also do not know what the equipment is. A list is available on request.

IBM 5110 power supply schematics?

by mattislind＠gmail.com

It turned out my friend was wrong. The power transformer is most likely ok. But one of the main choppers were short circuited (yes, it is a switcher, again to little info from my friend). Anyway. The chopper transistors were TI made in 1978 but marked T484. Probably some IBM marking which no one has the cross for. I replaced them with nice high voltage high current TO3 transistors The only thing i could get from the original transistors except for the physical appearance was the polarity. With a 5.6 ohm resistor on the 5V i fired up the PSU with a 60W lamp in series with one of the mains leads. Nothing happened on the bases of the switchers until I got to around 190 VAC input. At that point the base went high and stayed there. Really strange. Of course I have no schematics for this IBM thingie. Does anyone have a schematic for the IBM 5110 PSU? I think I really need it to understand what is going on. Tracing it out is an option but then all those square metal canned IBM ICs... /Mattis

Nuke Redmond!

A fellow who was putting the air in "Microsoft Tire" (c) is going to prison. Microsoft claims that the air they give free with the tire is not free. You can download the air and install the air and use the air, but noone can help you do it or they will spend 15months in federal prison and pay 3/4 of a million beans in damages for helping you and charging nothing for it but a quarter for the electricity it cost to put the air in. https://www.latimes.com/business/technology/la-fi-tn-microsoft-copyright-20… Jeff

Tandem Minicomputers

by silent700＠gmail.com

Well I said no more computers I can't lift, but exotic systems keep finding me. So today we pulled a Tandem CLX out of a basement, along with a few boxes of docs, 9-track tapes and random odd and ends: https://photos.app.goo.gl/m2N7RKN3JXcmVTUC8 There's such as thing as "so obscure that no one knows/cares about it". I've had those before. Do I have another? It sure is heavy. -j

Able document at VCF Midwest

by jnc＠mercury.lcs.mit.edu

This is a long shot, but... There was an Able Computer document at VCF Midwest, and through a miscommunication, it wound up on the 'free' pile. Did anyone here get it? If so, I'd like to try and get it scanned in, and made available. The thing is that documentation for Able products is hyper-rare; we only have those for the UNIVERTER and QNIVERTER, and some preliminary notes for the ENABLE. So if this can somehow be located... And while I'm at it, if anyone has any documentation on other Able products (there's a list here: http://gunkies.org/wiki/Able_Computer which I think is fairly complete), it would be great to get that scanned in too. (Not advertising brochures, we have a couple of them.) Thanks! Noel

Fw: [rescue] Very Last Chance - E6000 and/or parts

by Arno_1983＠gmx.de

Hi everybody, as I don't recall seeing this offer around here (may be just rusty memory on my side however...), I thought I'd forward this for good measure. I'm considering making the 2k mi trip together with my Dad but would do so only as a last resort to save the machine from being scrapped. I think I have some excess CPU boards, maybe a clock board, spacers and PCU/fan boxes from a gutted E4k class machine here (southern Germany) so I might be able to help people looking for parts. So long, Arno // DO4NAK > Message: 5 > Date: Sun, 6 Oct 2019 14:26:06 +0000 (UTC) > From: Mike Spooner<mikes at aalin.co.uk> > To: The Rescue List<rescue at sunhelp.org> > Subject: [rescue] Very Last Chance - E6000 and/or parts > Message-ID: > <90BB83AE79EC6FAC.9de3eb44-8314-4e62-b390-172d0a54745f at mail.outlook.com> > > Content-Type: text/plain; charset="us-ascii" > > In spite of my efforts to find a good home for my 18x250MHz Sun Enterprise E6000 a couple of months ago, I still have it.

Computer Automation Alpha LSI minicomputer

by dwcar49us＠yahoo.com

Hi, I am restoring a Computer Automation Alpha LSI/2 minicomputer and need some help with software documentation.?I have a?Computer Automation Alpha LSI/2 minicomputer and cards, and I have binary images of the paper tapes, but I don't have the manual for using the software library tools. By any chance does anyone have any of the documentation for the standard software library that came with the machine? BLD, OMEGA, LAMBDA, STP, etc? There was a standard paper tape that had all the basic software for assembly language coding and for loading and linking. The tape images are on bitsavers.org, but the manuals don't seem to be available. The manual was called the Software Documentation Manual.? Thanks for your help. David Carroll
