Hi, I have the following tram and I don't know what it is. It is manufactured by T2 Systems Ltd and is called a "Paradise 1/A" tram. It is a size 4 tram that has a T80x transputer on it. It also contains what looks like an IDC 50-pin connector (I didn;t count the pins, so I could be wrong). Does anyone know what it is?? Someone told me that it might be a data aquisition board (the IDC 50 looks like a connector for data aquisition according to this guy) but he can be wrong. If it is a DAQ card, what can I use it for?? Thanks Ram -- ,,,, /'^'\ ( o o ) -oOOO--(_)--OOOo------------------------------------- | Ram Meenakshisundaram | Senior Software Engineer | OpenLink Financial Inc | .oooO Phone: (516) 227-6600 x267 | ( ) Oooo.

Disk Drive Documents

by edick＠idcomm.com

While fumbling around among some old stuff in the basement, I found a notebook which contains the OEM and service manuals for the following SHUGART 8" Floppy Drives. 800/801, 850/851, 860/861, 600-series Siemens 8" Floppy Drives FDD 100-8 (2 versions, quite different, same part number) User (OEM) Manuals only Seagate Technology 5-1/4" Winchesters Model 506, 406, 409, 412 Persci Model 270, model 277 If this stuff is worth preserving, perhaps there's a way to save scanned images for eventual conversion to PDF. Does anyone know about this? Dick

plain great luck

by Jgzabol＠aol.com

Hi all, today some quite unbelievable piece of luck happened to me: While I was walking by the back entrance of a smaller University here in Minneapolis purely accidentally, not thinking about computers at all, I ran into a pile of electronics. Short investigation revealed that it was a 1965 CDC 3000 series hard drive electronics cage (14" removable pack electronics), perfectly undamaged and complete with all the ~150 cards (it so happened that I worked on an identical cage about 15 years ago), plus a heap of cards from assorted ~1971 Univac / Burroughs machines ! Within the next hour I found out that the building will be completely remodeled, and had to be emptied out. Quite obviously, someone forgot about 25 years ago this set of things in the second-level basement; nothing else there, though. General lesson: we should ask all schools regularly for their renovation projects !! John G. Zabolitzky P.S. If anyone knows about / wants to get rid of CDC equipment of that vintage, please let me know !

Specs wanted: Pertec Interface (tape drives)

by jimw＠agora.rdrop.com

Out on another info quest... Just added a couple of Kennedy 9610, 9-track tape drives to the collection (nice since they are multi-density 800 thru 6260) and of course have no docs on them... (ain't it always the way?) So in particular, I'd like to find some tech info on the (so called) "Pertec Interface" so I can figure out what various systems in the collection I might be able to convince these critters to work with. (and get a bit more knowledge on tape drive interfacing in general) Any assistance, pointers, spare docs, etc., most welcome!

RSTS/E V9.7 sysgen

by jpl15＠netcom.com

I believe I have located the appropriate materials to allow me to sysgen my 11/44 RSTS/E system, in order to add support for RL02s,and maybe RX02s and a few other things.... I have obviously never essayed this task before, though I *have* sysgenned a number of smaller CP/M systems, and I think I understand the basics of what/why. If there is anyone on The List reading this who has done this (sysgenning RSTS) before, and *especially* if there are big gaping booby traps to fall into... I would be most interested in the benefit of your experience. The install.log is available from the previous sysgen, so I have all the responses to the dialogs. Like (duh!) ought I to back up what I have now? [how does one do this to MS0: 1/2" tape?] Ought I to partition the drive? Does the process overlay the existing OS areas, or does it start over completely? And please don't jam me about RTFM... even if I *had* them I'm sure I'd have a bunch of other newbie questions.... ;} Cheers and thanks... John

While we're on the subject of decaying rubber in an HP85, I would add, don't try to run the printer until you have opened the unit up and freed off the drive belts - one for paper advance, one for print head. These belts go sticky and stick to the pulleys, so that when you try and run the machine they tear themselves to bits. It's a pity you weren't here a few months ago - a number of us got together and bought a bulk order of replacement belts very cheaply. I still have a spare pair if you're desperate, and I imagine one or two others may. FWIW the teeth on these belts are pitched at 0.080 inch - the standard "mini pitch", unlike some equipment I have which uses belts with the teeth at 0.081 inch...

Card Reader - HELP!

by leec＠slip.net

Hi all, I'm working on a volunteer project at the Computer History Center to interface a Documation desk top 80-column card reader to an IBM PC. The card reader is in very good condition, however we have no documentation for it. Do you know of, have, or can you provide pointers to any documentation for this device, how to interface to it, or operational information? On the back panel of the reader is a plate which lists the model as Documation "Model RM/TRM 10.12L-10.12C", with a sticker on the front with "Model 10.L12+", and operates at 115V 6.1A. The reader has a 1" x 2" (approximately) data connector on the back with this layout: +---------------------+ | O O O O | | O O O O | | O O O O O O | | O O O O | + | O X O | + | O O O O | | O O O O O O | | O O O O | | O O O O | +---------------------+ Legend: O female connector X Connector screw hole in center of the recepticle + Guide holes where the hood would attach The data connector is similar to, but isn't, a V.35 connector. TIA for your help. Please respond via email or phone. Thanks! Lee Courtney (650) 964-7052 leec AT-SIGN slip DOT net

VXT2000 info needed

by cfandt＠netsync.net

Hi folks, I went to the Rochester Hamfest on 5 June. Amongst other radio and computer items I dragged home were two VXT2000 boxes. No displays or keyboards, just the pizza boxes. The guy literally gave them to me when I was at his fleamarket space as he was starting to packup and go home just because I was studying them intently (I never saw one before). That'll learn me not to stare so dang long at somethin' an' get nabbed by the owner! My wife was there too. She just rolled her eyes after the 'transaction'. At least she carried the NOS P54 motherboard and parts we found for my stepson's computer upgrade plus some radio parts and manuals after I got handed the VXT's. These I understand are X-terminals but I know nothing else about them. Searching the usual places for useful info only told me they were X-terms. Could anybody provide more info to a curious mind as to what the hardware details are, their typical usage, any other details, etc.? Specific model numbers are VX20A-AA and VX20A-BC. I see the -AA has color video output and the -BC is monochrome. Seem to be the only hardware diffs. Will the good old LK201 keyboard work with these? What about the mono video: will the VT240 mono monitor work with the -BC? Kinda classy-lookin' hardware inside. Useful for anything (seriously)? Off-list please as these are really less than 10 years old. Thanks in advance for your usual good info!

pdp11/70 console manual.

by mcquiggi＠sfu.ca

Hi Erik: Thanks for the email. You'll need the Processor Handbook for the 11/70. It tells all about how to use the front panel. If you need schematics (probably not at this stage) then I can assist. I don't have the processor handbook, I suggest that you post on the classiccmp list and one of several people (Tony, Megan, Allison, Tim, ...) will likely respond with an offer to photocopy the relevant sections. I run a pdp-8 web site, one friend runs a pdp-11 web site on my machine. He may have posted the 11/70 manual in scanned form, or may have it and be able to scan it/copy it for you. Check out http://highgate.comm.sfu.ca/~rcini. Good luck, Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca

VAXstation 3100

by allisonp＠world.std.com

<I can pick up a VAXstation 3100 (just the box, no monitor/keyboard/etc). <Is this worth messing with? Yes for OSs there are three choices, VMS, Ultrix and NetBSD. There is a free license for the first one and the last one is not quite ready for prime time(unless you really like to work at it). <What's in it processor wise? Vax! Without a specific model number it's hard to be more specific. They are all VAX, the difference being speed and added performance. Of it's an older one it's like Cvax, later Nvax, most recent SOC. Most 3100s are SCSI for disks and tape, have eithernet and several serial ports so they can be quite useful for routers, mailservers, WWW servers and the like. < Can I rig it to a VGA monitor? Never tried, uses some high scan rates and very high resolution. However if that fails you can plug a terminal into the back and talk to it that way. <Should I let it pass? I'm biased, never!

VAXstation CDROM questions (again)

by allisonp＠world.std.com

<I assume the SCSI cable required is the old style 68? pin (female) Yes the M76 requires the 68pin at one end cable.

by danburrows＠mindspring.com

> >You know of one for $25.00? That doesn't require and IRQ for every port? See if your version of Linux supports Digiboards. If so I have a bunch but I will need time to make a list. They are 2, 4, 8 and 16 port version and the 8 and 16 port ones that I have played with so far you can run with either no interrupts under NT4. I only have a few cab kits however so you may have to make a cable set. I think I have the pinout info. Contact me off list for further details.
