Hmm. Did you find out anything more about this?
I found a copy of _Introduction to DECSYSTEM-20 Assembly Language
Programming_ (by Ralph E. Gorin, 1981, published by Digital Press,
ISBN 0-932376-12-6) and was thinking that this was good timing because
I might actually be able to do the homework on, well, something like a
-10. In my dreams^H^H^H^H^H^Hcopious free time, of course.

I seem to recall reading somewhere (BYTE ~1985 ?) that Soviet made CPUs
(6502 clones?) were so poorly maid that they individually came with a
list of which instuctions worked and which didn't. Also seem to recall
an article on the soviet Apple ][ clone of the time (CPU on a large
daughterboard, pirated ROM, cost approx US $20,000)

Sure it was. The Franklins were probably the best known Apple rip-offs
^H^H^H^H^H^H^H^H er ah, clones. At least until Apple sued them and
Franklin had to actually design their own machines.
>So the Soviets pirated the Apple ][, who didn't?
But you missed the point. No other >COUNTRY< tried to pass off a pirated
machine as their own. In fact, most cloners (pirates?) bragged about their
similarity to the original machine, the Soviets claimed that their machine
was an original design. To top it all off, they didn't even have the good
sense to change the copywrite notice!

That would probably be a pretty big collection just by itself!

The Cray-1 was ECL-10k fast for it's time but low density and rams for
that technology were 1 or 4k ECL bipolar. ECL had several
characteristics, FAST, high power consumption and low density. The
copper plate worked with a cooling system to conduct the heat away as
that machine was impossible to air cool and remain that small. Why
small? Conductors propagate singnals at 1nS a foot and a cable of several
feet actually represented a significant delay to the overall sheme of
things inside.
A note: The other commonly known and slightly more recent ECL machine
was the DEC VAX9000, built using ECL-100k built on custom air cooled
hybrids. It also consumed power in great quantities and had special
cooling considerations.

Your could but the interface would be more than the two combined and it
would eat an amazing amount of power.

The DHV 11 manual and the programming card have both been claimed. Given
that the hardware is on hold, that completes this run of freebies.
Thanks to all for your interest.

I've acquired a Amiga 1000 with monitor, mouse, scsi sidecar that try's
to boot up, but after booting kickstart, it asks for the Workbench 1.2
disk. My disk seems to be defective because the drive cycles and the
picture of the workbench disk comes back up. Does anyone out there have
a copy?

Is the reason those old radio/phonograph boxes are not being thrown
away is that noone notice the cover and thinks it's just a pretty
dresser w/o drawers :)? Also hideaway sewing machines.
I do see many of them in thrift stores, though. It was a good idea,
to keep technology invisible. Now, it's the other way around.
Cover EVERYthing with black and beige boxes.
Of course, the System/36 (I think, maybe not) was built into a desk.
And then there were the teletypes (are the ones that are mostly used
as examples of teletypes ASR-33?), printers, etc.

I found this on E-bay. The minimum bid is $45. If you think this is too
much (I do!!), you can contact the owner and see if he'll take less if it
doesn't sell. The URL is

AFAIR the ordinary probes are just micro-hooks on single wires, which plug
into a little distribution box on the end of a ribbon cable.
It's quite a nice analyser, so "play with it" gets my vote. It was also
quite popular, so I expect you could find manuals if you look/ask around.
I'm sure we have some 1611s or 1610s in the labs. If you want me to take
a look at them next week, shout. There's also a description of both
models, and several examples of use, in John Lenk's book "How To
Troubleshoot And Repair Microcomputers" -- which IMHO isn't a very good
book, but there seem to be lots of old copies of it about, and in
libraries.

Interesting. I was in the library today, and I happened to glance
on the back of a VT-220 they had. I thought it was video, because of
the icon, but then I said to my friend, "Cool! It can do ethernet!"
