What about an IBM XT with a Big Blue CP/M Card, AND a Trackstar 128 AND a Hydra (MacPlus) board? Wouldn't that give you 4 processors in one machine? One could also run an Amiga with an 8088 Bridge board for dual processors. Or, an Apple IIe, IIgs with a Transwarp card for two processors? Three if it has a Microsoft Softcard... Which makes me think of the Zip Chip and Rocket Chip for the Apple IIe/IIgs series. Did these chips also work in the C64 and other 6502 machines? I remember working with them, but don't have one for either of my IIgs machines... I *DO* have an Orange PC card that will turn a PCI Mac into a PC. But, I don't have the required cable or software for it. So, it's merely a curiosity at this time. That would make a Mac a Dual Processor machine, wouldn't it?

AT&T 730 MGT graphic terminals

From: Richard <legalize at xmission.com> > Anyone know anything about these? Google for AT&T 5620 and/or AT&T BLIT. The 730 is a descendant. > Apparently they could be used as X terminals and they are essentially > diskless workstations with a 68000 inside. They can be regular dumb terminals or "layers" terminals, which is a really rather interesting, pre-XTerminal remote windowing system worked on by, among other luminaries, Rob Pike. As I recall, they came out with an X cartridge for the 730 since layers never caught on. I only saw NCR rebadged X Terminals during my time at AT&T, so I assume the X cartridge didn't catch on either, even internally. > Any AT&T 3B2 owners out there have one of these in a working state? Don't think many of them ever made it out of AT&T...at least I've never seen one in the wild.

rogues / Rare european machines

Apparently not, at least for some of the Eastern Bloc clones; see http://hampage.hu/tpa/e_index.html. For the Hungarian machines, cards were definitely physically different, I'm betting things like power supplies are local creations and anything using LSI (F-11 clones, for example) were undoubtedly somewhat original due to differences in the manufacturing processes the Soviets had access to (and DEC never made anything that looked like a K1801VM1). Very faithful clones as far as the software was concerned, though.

multiple cpu machines Re: rogues galleries

If you can find a Hauppauge 4860, you get an i486 and an i860. Toss in a DAC960E EISA Raid controller and you get an i960. And an NE3200 EISA network card, and get an i80186. Add a National Instruments AT-DSP2200 EISA data acquisition card, and you get an AT&T DSP32C. Add a A Hercules Graphics Station card and get a ti34010. Add an Opus card or two and get more (mc88100? SPARC?). That's 8 processors, 6 of which are directly available for fiddling. I've had, at one time or another, all these cards, but since I never put them together, I guess I don't win.

I assume, if they are taken off without damage to them, they would simple clip back on? I have never taken a keyboard apart yet, and will no doubt need to someday. I probably won't bother until a keyboard, or keys, starts failing. Regards, Andrew B aliensrcooluk at yahoo.co.uk

Good home required for a set of HP 9000 model 375 manuals.

by andy.piercy＠gmail.com

If anyone would like a full set of HP 9000 manuals please contact this guy off list as they are heading for the skip! He has just posted to the UK a full set of Masscomp manuals so he is very helpful, he is located in the USA in Kingstowne VA. "I just wish I could find as good a home for our set of HP 9000 model 375 manuals. There was a guy in France, but he cannot afford the postage. Now even the janitorial staff won't take them out for me; the pile just sits there with the "Trash--please remove" sign on top. :-(" Please reply off list to: "Newquist, Jonathan D" <NewquistJ at state.gov>
