<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.

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.

I had never seen that Toshiba chip before. The 2716 was just a guess
based on the part number. I'd guess that it's 200ns RAM. Is it a 2kw
chip?
The Toshiba part was a regular 2016/6116 2KBx8 static RAM. Same pinout
as the 2716 except for the additional WR* line. IIRC there were LP (low
power CMOS) versions too, various speed grades.

That's possible, but the probes themselves definitely are just wires with

Well thanks for letting me put the things I had up here on the list.
I've sold or traded both the Kontron logic analyzer pair and the Tek

I still have a single channel 10mhz RCA solid state scope in great
(looks new, works new) shape with manual. It's a model WO-535A and is

I have a book that hasn't even been used here that may be of interest to
those of you into vitual programming on a PC.
The title is "Playing God - Creating Virtual Worlds With REND386" by the
Bernie Rohl and published by the Waite Group. Includes a still-sealed
3.5" disk fullof source code for C++ and other neat looking things. Made
to run on a 386SX to a Pentium machine with VGA, 4mb RAM and a hard
disk. It says it's an intermediate level book.
The cover price on this glossy softcover with disk is $29.95. Anyone
interested in it? You can have it for $15 which includes mailing within
the continental 48 states.

Now this is interesting---Perseus Development Corporation developed a new

OK... here's the current scoop. Sam Ismail has claimed the DEC networking
book and the Microsystems handbook. I still have available the DHV11
technical manual, the Everex manual, and the DEC programming card.
The remainder of the hardware is on hold pending a possible taker. Thanks
to all those who responded.

"Our science can only describe an object, event, or living thing in our own

It seems to be all in the very preliminary stages, but time is running
out...
Does anyone on the list have space for a large (two-rack) Multiflow Trace
machine? One has popped up, and it seems that RCS/RI has a big interest in
it, but we might run out of time before we can set up a mover. A cormer of
a garage might be nice for just a short time, just in case the machine's
current owner needs the thing out of the San Diego place on short notice.
If RCS/RI just can not pull this off, does anyone want the thing?

Ok, since I intend to use this thing to work on computer related gear older
than 10 years old (my 083 card sorter for example), I'm proclaiming this
inquiry off-limits for random flamage! B^}
Does anyone out there have info (like the tube/switch charts) for an EICO
Model 635 portable tube tester? I've picked up one that is in very good
shape, but is otherwise useless without the charts for switch settings.

I'll be having fun friday...
I get to go argue with a professional junk guy over a KS-10. The company that
owns it wanted it melted down, to protect some confidential data they had on it.
SO, I'm gonna say "None of your data is on the CPU, just the disk packs,
so he can have the packs. There." The drives are 2 RP06es. (Yes, I know I
need 3-phase. Mark says he knows where to get an RM80 or two. Is there
any way around having to have 3-phase for the RPs? I was told they fail every
other 10 minutes, is it even worth it?) It did run TOPS-20, but I'm chasing
after ITS tapes for it. Even if I don't end up getting it, I may get the CPU
cards and backpanels, and then I know someone who has the rest of a KS.
Failing that, if the junk guy gets everything, I know someone else who has
a whole KS, but no operating system. So, one way or another, we're gonna get
a running ITS installation out of this...
Am I supposed to be this nervous?
I've never had to actually argue with a junk guy over a machine, in front of
a buncha suits... (Division heads or something. The actual company is QUITE
large... *hint* *hint*...)

You can't have mine.
MINDSET was about as you recall. It built in 1984 as a super-multimedia
80186-based PC-compatible (well, mostly-compatible, anyway.) For 1984,
the graphics were superb and it had (IIRC) a video-in connection so you
can use the computer as a character generator/paintbox. I think it was
packed with a low-end cousin to the Time Arts Lumena paint program and
was THE machine for graphic artists. Remember, this was a year and a half
before the Amiga - which, whene IT came out, pretty much took over
Mindset's market.
The Mindset has a unique and quite beautiful white bi-level case design.
So pretty in fact that the Museum of Modern Art put one in their design
collection - the first computer placed in their collections.
Much of the hardware was proprietary - weird memory modules and it also
accepted plug in progrram cartridges.
Mindset didn't last too long as a company. They DID build a second model,
an AT-based machine in charcoal gray. I've seen it once and never read
anything about it
I found my original Mindset last year, complete with a couple of
expansion RAM modules, the boot disks and the paint cartridge.
Like I said, it's gorgeous and you can't have it. Nyah. But - I might
make you a deal on the stereo module!
