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?

Google for AT&T 5620 and/or AT&T BLIT. The 730 is a descendant.

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.

Don't think many of them ever made it out of AT&T...at least I've never seen
one in the wild.

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.
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.
Ha ha, I knew you you'd read it!
Actually, I'm testing Yahoo's delivery.

How easy is it to take the plastic (?) keys
off of a keyboard without damaging either
the keys or the contacts underneath?
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.
