Did some of the Taligent codebase end up in SUN's Java implementation, perhaps the libraries? I encourage you to add to the story of Taligent. I remember at the time Taligent gained a lot of press attention, particularly when Apple was struggling with what to do with their operating system and Pink was seen as the answer.

first unix experiences

by barythrin＠gmail.com

My first glimpse of a unix shell was a bit obscure and late in the game (it was obsolete at the time) but I'm curious if someone here can confirm/guess what it was. It was large desktop machine and I can't quite remember if it was side by side (think full height) 8" floppy drives. It was at a computer repair store as something to play/learn on. Unfortunately this was probably mid 90s so no help as to the actual year the machine was in production. I had always wanted to buy it off the store but they disappeared before I had any paying job or opportunity. I'm guessing it was a Vax but since I haven't really seen may first hand other than my 3000 did they come as 8" floppy desktops?

SunOS on 3/50s, 3/60s, with a server and thick Ethernet cabling. This was around 1986 to 1988, while I was in graduate school. After that, 1994 to 1999, it was administering a whole office full of Sun networked workstations (10, 20, UltraSparc). My first non-Sun Unix experience was testing BSD on a small PC. As one you has never really had DEC PDP-11 or Vax experience to any extent, I look at those computers and think more about wanting to put Ultrix or some other Unix/BSD/Linux system on them and don't think nostalgic about DEC operating systems. My first big computer experience (not counting some timeshare Basic programming on MECC/MERITS systems in Minnesota) from 1977 to 1981 in college was with Harris computers running Vulcan or VOS. That is my frame of reference for major computer, followed by SunOS/Solaris. Today my operating system of choice is Linux (e.g., Xubuntu). Having said that, I do have a healthy respect and admiration to those of you here who know PDP-11 and Vax systems, plus before that PDP-8 and things like OS/8. Let alone the various obscure systems. I just can't relate at the same time. Kevin Anderson a lurking subscriber from Iowa

HP 1820-1584 IC replacement?

by hp-fix＠xs4all.nl

Bob, Those hp parts, the expansion bus uses them also. If you don't use a rom module you can use on of them, they're located near the rom connector. Rik -----Oorspronkelijk bericht----- Van: "Bob Rosenbloom" <bobalan at sbcglobal.net> Verzonden: ?11-?5-?2013 07:40 Aan: "On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Onderwerp: HP 1820-1584 IC replacement? I have an HP 9872 plotter that just died. According to the internal self test (very nice!) one of the bib (MOS to TTL) drivers has failed. A scope shows one data line not moving also. The HP part number is 1820-1584. I can't find a cross reference on the web for it. Does anyone know if there's an equivalent chip? It's a 20 pin dip. +7 volts on pin 20, gnd on 10 MOS side is pins 1-8, TTL side is 12-19 A signal called TTL on pin 9 and another control signal, BD on pin 11 I would love to get this running again. Thanks, Bob

An IRIX time capsule...

by jon＠jonworld.com

Hi! This probably doesn't count as true vintage, since it's circa 1992 and is a 32-bit workstation. But it's an awesome score for something local to Indianapolis and as complete as it is, so I must brag. I just scored an SGI Indigo Iris, complete, with keyboard, mouse, 19" beige SGI monitor, two internal hard drives, floppy drive, DDS tape drive, and external CD-ROM, plus boxes full of software and books. It's a 33Mhz 16M system with an R3000 w/ math coprocessor. The stuff that came with it is even more interesting. The books include the full SGI document set; Iris software guide, Iris owners guide, programming guide, network programming guide, compiler guide, ANSI C transition guide, C language guide, C++ programming guide, (again, all SGI-branded.) There are also AT&T C++ Library guides, still in the shrink-wrap. There is also some vintage O'Rielly books like learning vi, the X11 programming manual. There are also two OSF/1 Motif programming manuals (Programmers guide, style guide.) Also included are guides for SoftPC AT, allowing up to a 286 to be run under Irix. I believe this is installed on the system but I have yet to test/verify. There are even more books, which are water damaged :( CDs include IRIX 4.0.5, IRIX 4.0.5 maintenance, Soft PC/AT 1.1, Hot Mix 1-6, and a few other odds and ends. Is any of this stuff BitSavers or the document archive website(s) would be interested in?

An IRIX time capsule...

by elson＠pico-systems.com

A while ago, somebody put an SGI IRIS 2020 out on the loading dock of the computer science building at work, where they often put things they think somebody might want to tinker with. I dragged it over to my building and plugged it in, and the console monitor came up. That machine had almost a Unix shell as the console monitor, you could read files off the disk and such. Well, I took it home and after consulting with some people online who know the model, it was determined that the geometry engine was bad. I found a guy in Germany who had all the boards and shipped them to me for a couple hundred Dollars. I plugged the GE board in, and it booted IRIX. I got the guy who wrote the SGI flight sim demo to send me the source code, compiled it, and it worked. (He has asked me not to name him, as that program is under SGI copyright.) It had a quirk due to using the GE's matrix transforms to do ALL 3D arithmetic, including the "flight dynamics". It would get "stuck" at the 4 main compass points. I never figured out how to recode that to use standard C arithmetic. It was a cool toy, but then 3DFX and similar PC graphics boards came out and Flight Gear was created. The replacement GE board eventually also failed, and although I had plenty of chips to swap to repair it, I didn't have the diags to find out which one was bad. I eventually sold all the boards to a broker to use for repairs. Apparently the Air Force still uses them, I'm guessing maybe for flight simulators. Jon

Manual for CMD CQD-240/TM

by lbickley＠bickleywest.com

I've searched in all the usual spots and haven't been able to find a CMD CQD-240/243 manual. It is a Qbus controller with both single-ended and differential SCSI capability. It looks similar to the CMD CQD-220 (manual on bitsavers) and the CMD CQD-720 (manual on bitsavers) - but has a different switch configuration with more options.

Anyone have a IBM Model 25-286 Riser card?

by raifield＠gmail.com

The 8086 versions of the Model 25 and Model 30 have 8-bit ISA risers, the 25 with a two-slot riser and the 30 with a three-slot riser. The 80286 versions of each have 16-bit ISA risers, again the Model 25 with two slots and the Model 30 with three. I tried plugging the 8-bit riser into the Model 30 286 board, but the system refused to power up. In addition, the Model 30 riser is incorrectly spaced to fit in the Model 25 all-in-one case. Even if I cut the top slot off, the remaining two don't line up at all. It looks like I need the genuine part, which no one seems to have anywhere.

follow up???? - offer - OS/2 for the PDP-11

by other＠oryx.cc

Hello All, I a new subscriber from just a few days ago, and I have spent more hours than I care to admit to going through all of the emails in the online archives. In past lives, I spent a lot of time with OS/2, and even though I don't spend as much time as I used to with it, OS/2 comments still catch my attention. Anyway, to get to the point, I caught this thread (bottom) from 2008 which generated a bunch of comments. The thread was briefly revived in early 2009. If there was ever a final fall out from the thread, I somehow missed it. Was there a version of OS/2 for CPU's other than X86 or PPC? What was ultimately found to be on the tape? Thank you, Jerry ------------------------------------------------------------------ Yes, you read that correctly. I have in my possession a TK-50 tape for the PDP-11 system which contains none other than OS/2 operating system. Many people have claimed this never existed. But I have the tape! I had done a directory dump of it and can supply it. One other person who's checked the directory listing has said it is authentic. I'm not sure what to do with it, and I believe IBM made OS/2 open source, so technically it should be "free" of it's chains maybe someone can turn it into something useful, or just run it and have the most unique PDP on the planet, I don't know... whatever :) anyhow, it's a really weird bit of computing history, and I'd hate for it to be lost. it should be in a museum :)

KA630 SLU details?

by mouse＠Rodents-Montreal.ORG

It's a bit of a long shot, I know, but is there anyone here who knows details of the KA630 (MicroVAX-II CPU) console serial line hardware? My emulator is failing selftest 2 and it appears to be because it's expecting the console serial line to act in some way mine does't. But it's not clear from the code what it's expecting, just that it's obviously different from what I've implemented. In particular, what I see in my instruction trace is: - set stuff up, including putting SLU in loopback - drop IPL - take transmitter-ready interrupt - tell it to transmit a NUL - REI - enter wait loop (with countdown timeout) - take transmitter-ready interrupt, long before countdown expires - do nothing that touches the SLU - REI - take transmitter-ready interrupt again immediately - fail the test But I thought real hardware acted this way: don't clear an interrupt condition and it fires immediately upon REI. So there's clearly something I don't understand going on, hence my question.... /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

https://www.msu.edu/~mrr/mycomp/terak/termubel.htm Lycklama's MINI-UNIX on an PDP-11/03, early 1980s for my first experience. MINI-UNIX was a cutdown UNIX V6 kernel that operated on a PDP-11 without MMU support, by swapping each process in and out of what little memory remained (12KW for the kernel and 16KW for user space). What made it somewhat usable for us was the very fast optically-positioned Pertec fixed/cartridge disk system (emulated an RK05) we had on the system at the time. It was essentially a single user environment, but the C compiler worked. I think we briefly tried two terminals (ADM3a) just to see if it would work. That experience lead us to later get an LSI-11/23 CPU board and additional memory and start running UNIX V7, and for a brief time we had 12 terminals connected with students able to do a mix of Pascal and simple FORTRAN programs (no one wanted to use C at that stage).

Downsizing - many systems available

by dave13＠dunfield.com

For various reasons I am looking to downsize my classic computer collection over the next few years. The collection can be seen at: www.classiccmp.org/dunfield [Keep trying if it says "service unavailable" - the classiccmp server seems to be having problems lately] Most of the system depicted are available. A few I will keep, a few are already placed, and a few are "on loan" and will be returned to their owners, but most of the systems shown are available (as well as a few which have not been processed yet). If you are interested in one or more systems from my site, please contact me off-list and let me know specifically what you are interested in. All of the equipment is located near Ottawa, Ontario Canada. If anyone is interested in the entire collection, let me know and perhaps we can work something out. If there is serious interest in the whole collection, I can make a detailed inventory of exactly what would be available.

Wanted: VR201 and LK201 for DEC Rainbow 100

by lists＠loomcom.com

Hi folks, At a local swap meet this morning, I stumble across a pair of DEC Rainbows. I got both of them for $45! Hey, no comments from the peanut gallery, _I_ think these are collectible anyway :) And they're getting really hard to find, so I'm happy. Unfortunately, as is all too often the case these days neither one had a keyboard or monitor with it. So I'm looking for at least one VR201 monitor and an LK201 keyboard. If you've got any spares floating around please drop me a line. I think they're starting to be unobtanium, which is really too bad. I'm located in the San Francisco Bay Area, by the way.

IBM I/O Selectric project

by lawrence＠ljw.me.uk

I've been working on an IBM Selectric typewriter which I bought earlier in the year. It is the I/O Selectric type 735 which differs from a normal Selectric in having the solenoids and switches on it to allow it to be used as a printer and keyboard. When I got it the motor wouldn't run, and the mechanism was jammed. The motor problem was its thermal trip, which is meant to be the resettable type, so I replaced that. I gave the whole thing a clean with degreaser, which freed up the mechanicals, then oiled and greased it. It then worked happily as a typewriter. I have made a small interface, based on an Arduino Mega 2560, which provides a serial port. Currently this only supports printing, but will be extended to include the keyboard. It uses almost all the digital I/O on the Mega (15 solenoids, 27 contacts.) There are still some adjustments to be done, and I am awaiting a set of Bristol Wrenches (Keys) so I can safely do these. I have tried using Torx and Allen keys, and while they can be made to 'fit', it doesn't seem like a good idea. There are some pictures and videos of the typewriter here: http://www.flickr.com/photos/ljw/sets/72157632841492802/ You can get the Arduino interface code here: https://github.com/ibm2030/IOSelectric I haven't yet documented the hardware I used for the solenoid drivers, but if anyone is interested I can put some notes together (basically: Arduino output to 2N7000 FET buffer to ITS4140N +48V high-side driver on the output side, and a simple 250R pullup to +5V on the input side.) Manuals here: http://bitsavers.informatik.uni-stuttgart.de/pdf/ibm/typewriter/selectric/ (or other Bitsavers mirrors) Info on the Mega2560 here: http://arduino.cc/en/Main/arduinoBoardMega2560 -- Lawrence Wilkinsonlawrence at ljw.me.uk The IBM 360/30 pagehttp://www.ljw.me.uk/ibm360

Source for replacement parts?

by earl＠baugh.org

I'm looking for a part for a Mac Studio display (and yes, I know this doesn't qualify as "classic" but I'm trying to find a good overall solution for this type of repair). The part that failed is a simple piece of metal in a hinge which seems fairly well designed for replacement. However, I've been unable to find any sources for the particular part, Apple, etc. don't seem to have anything available. I do see some sites that have the entire hinge assembly available in the $18-$20 range, but I've been able to pick up entire monitors of this type for $25, so this really doesn't seem to make sense to pay this much for just the hinge when I could get a full set of spares (or even yet ANOTHER working monitor with the same issue). I'm wondering how people solve "spare/parts" issues like this. I've posted something to http://www.shapeways.com/ to see if someone would model the existing part, which I could then get them to fabricate. Not sure if that's going to be cost effective either (unless I order some quantity and sell extras with a mark up...) Earl p.s. A big thanks for the advise on the lubrication for the floppy drives. I ordered some of the Drislide which works excellently. A simple cleaning job with straight isopropyl alcohol, a couple drops, and all three floppy drives are now working as good as new...
