M700 System Tape

by jolminkh＠nsw.bigpond.net.au

I have found a micro cassette labelled M700 System Tape, dated 1989. Anyone have any idea what this might have been for? Found in a stratum with lots of computer and software manuals from the same period. Hans Olminkhof

Looking for VMEbus module manuals

by cfandt＠netsync.net

I have a couple of Mizar VMEbus Video boards, model 7710. Has anybody an operator's/technical manual? Either an original or decent xerographic copy will do. Has anybody written an OS-9/68K ver. 2.3 or 2.4 driver for this thing? These are 1989 vintage. I'm also looking for the following Motorola VMEbus Module manuals: ** MVME 236-1,2,3 (Publication number MVME 236-1 Dx ), DRAM memory module (x = version or edition number. I'll take any version.) ** MVME 133-1 ( " " MVME 133-1 Dx ), Processor module ** Support Docs manual for this processor: SIMVME133-1 ** MVME134bug ( " " MVME134bug Dx ), debugger manual for '134 processor module ** and finally the Support Documentation (schematics, etc.) for an MVME147S which is publication number SIMVME147S. Already have the manual. ** I'm also looking for Xycom catalogs and any tech documentation from back in the mid-80's. Thanks for your help! Regards, Chris PS: Are there any of you out there who have VMEbus gear in your collection? -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA cfandt(a)netsync.net Member of Antique Wireless Association URL: http://www.ggw.org/awa

the "FIRST PC" - How about the computer on the Lunar Module?

by edick＠idcomm.com

Really! The original "Lunar Lander" game . . . I often marvel at how they manage these decade-long development cycles. Imagine the apparent lunacy of launching a 10-year-old design just because it takes that long to integrate, manufacture, and test it. The simulator must have been written in Threetran . . .

the "FIRST PC" - How about the computer on the Lunar Module?

by jlewczyk＠his.com

I was watching the show on the history of computers on the Discovery channel and they talked about the computer on the Lunar Module that landed on the moon. It had 5000 integrated circuits in it and was quite the marvel for its time. Could this be a candidate for the first Personal Computer? They were kinda pricey! ;-) Does anybody have any information on that cpu - word size, instruction set, memory, control panel, etc? Who manuafactured it? Where can one go and see it (without going to the moon!) How about the software for it?

Anyone have an old plotter that they don't need???

by roblwill＠usaor.net

Hello. I'm working on a project for the TSA National Conference (Technology Student Association- www.tsawww.org ). It's a CAD design project, and printouts need to be made at the competition. Unfortunately, my plotter just coughed up and died this afternoon. It started to grind, made a loud pop, and some smoke puffed out of it. I took it apart (thought it was a P/S problem, since the P/S died once before), but it seemed that the decoder (?) chip had fried. It's an old Tandy, so doubt I'll be able to find any new parts for it, and I wouldn't have time to repair it, anyway. My school does have a plotter (2 year old HP), but they won't let me take that beast to Tulsa for the competition (I'm not quite sure how I'd get it there, either). I'm not looking for anything real fancy - one with just a black pen will work fine. As long as it works (with a PC - PS/2 P70), is fairly portable (can be carried by one person), and won't cost me that much.

My 7945s are 55MB hard drives period, there's nothing removable unless you have a screwdriver. OK, if you look inside there is probably a ~60MB Priam/Vertex MFM/ST-506 i/f drive, and one or two printed-circuit boards to speak CS/80 over HP-IB out one side, and MFM out the other to talk to the drive. There is a 68xx playing microcontroller to run the drive (on the board with the HP-IB connector) but it wasn't sold as a computer and I'm pretty sure it's intended to be user-programmable. -Frank McConnell

GEM GPL'd?

It's not a rumor, the source code for GEM has been released and is available on the unofficial CP/M web site. The heritage of this source code was unknown a few days ago, it was not known either if it would compile, or how close [or far] it was related to the shipping products. But it's a starting point.

If you find that the toroidal ferrites that Siemens and people make don't have enough hysteresis, why not go to the other extreme and try the stuff magnets are made of.

I think what he meant was: Rather than sending write current through all core planes and inhibit current back through those to which you don't want to write, why not send write current only through those planes to which you want to write? My initial guess was that you might connect the write wires of several planes in series, and have a single driver for the lot.

stupid vax tricks

by red＠bears.org

ok, tonight's stupid vax trick is deciphering the wonderous boot messages. I've gotten the SPX card I was supposed to have, and things are looking much better now than they had been before. But (always the 'but'!) The boot fails in an entirely different manner now. Tests A, 3, and 2 give a '_' result which as I understand means whatever it was testing wasn't found to test. Test 1 gives a '?' and I get this message: ? 6 80A1 0000.4001 ?? 1 00C0 0011.700E >>> continue ?24 UNXINT 00010000 041F0000 01C and then nothing more. If I run the proper 'show' command (forgot which one I used) the disks spin up (RZ23 and RZ24), and 'show boot' indicates it wants to boot from the RZ24. Help! I really do not know what I'm doing.
