And then several people posted "tell me more". All I know is
I found a mention via a search engine of three Teraks that were
about to be tossed to their surplus center, and when I called
the surplus center (University Surplus Property Warehouse, 206-685-1573)
they said they auction 60-70 pallets of computers each month, so
they had no recollection of these Teraks. Someone in the UW area
must've got them! I hope they're not dumpstered. I also hold a
slim hope that they weren't sold, and are still for sale.
See my web site for an image of a Terak. Find them and send
them to me. :-)

I didn't bother to ask when I saw the announcement -- no time to dink
with it then and no good idea what I would do with it except log in and
look around. Well, I guess I've found a solution to that latter part,
now if I could just do something about the former.

OK.. Manney has one, but hasn't gotten back to me on it yet. So anyway,
here's the deal: I'm moving this summer, and so I need to stay online.
(Yes, NEED, as I'm a panel member for http://www.webhostlist.com , so I NEED
to stay connected.)
So anyway, what I need is a laptop, or a hand held, that has TCP/IP
stacks and a graphical interface for it (so that could be a 386 or later, or
a newton, Mac, or anything else...)
Oh, and this is intended to be a REALLY low cost thingy...

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!

The Cray-1 was ECL-10k fast for it's time but low density and rams for

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

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.

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.

[Stopping thinnet with a 3270 card...]
I once heard of a manager of some sort plugging thinnet into the back
of a VT220 (?It was VTsomething...?) video-out port. Seems he thought
it was one of those network computer deals...
VT220s had a video out BNC connector. You could drive a monitor with
it, but wasn't very useful plugged into a coax Ethernet cable.

Yes, happend at DEC sometimes. DEC had VAXmate (AT class) machine that
was netbootable and could do file sharing via eithernet. There were also
X-terminals (DECmindows) that used the net for both the hookup and loading
operating software.

<Excuse my ignorance, what does ECL stand for?
ECL or emitter coupled logic is a form is bipolar logic that operates
at low levels and is non saturating. Non saturating is where the active
devices are neither fully off or fully on. Logic levels are referenced
to a bias level so translation to MOS/CMOS/TTL is required. The reason
for doing non-saturated logic is speed, transistors have a problem like
tubes of charge storage making them harder to turn on or off and reducing
speed. Generally speaking from the late '60s through the '80s ECL managed
to be a factor of 5-20 times faster than the prevailing logic system(RTL,
DTL, TTL) until sub-micron CMOS started to get under 10ns. The last ECL
parts I looked at(years ago) were sub 1nS and could be clocked faster than
1000mhz. An example of the speed difference is 1974 the fastest TTL
divide by 10 (7490) was maybe 35mhz, ECL divide by 10 was 500mhz.

Yes, for certain sorts of useful. You plug the BNC T onto the back of
the card, and it stops all communication on that thin-net segment. At
least that's my experience with such devices. (They told me it was an
Ethernet card. I didn't believe them but they insisted, so I shrugged
and plugged the cable in. It took about five minutes for the
folks hollering from the other lab room to find me.)
If you want an MCA Ethernet card, look for one with both a BNC
connector and a 15-pin D (AUI) connector. Maybe an RJ45 too but
I don't recall seeing many MCA cards that had all three connectors.
-Frank McConnell
If nobody wants the Kaypro PeeCee, I suppose I could pull all of the cards
out for interested parties and ship them. If, however, someone wants the
machine whole, obviously it will be kept whole.
