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.

Today, I received the MCA network card Russ Blakeman sent me.
Unfortunately, it is called a "3270". I am afraid that it's not a
real net card, but a 3270 emulator.It has a BNC connector on the
back. The driver is called "3270 Driver Revision B".
Can I use this thing with ethernet?

Nope!

The SDS was only one board, TelTEK actually had three different ones for
slave or master use. The master board also had an FDC on it.

Yep. Nice board too! Got to try out the proto and it was fast!

I had SIO (two serial ports) and a parallel printer port.
Don't remember SASI on that but it did have 765 FDC that could be used
for 8/5.25/3.5" floppies.

There wasn't much other that configuring it with MP/M as a slave.

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.
SDS (S.D. Sales) made an S-100 similar to the Teletek, except it could
be configured as either a bus master main Z80 CPU card or a slave card.
In master mode it had a memory manager, I think the full 24 bits. In
slave mode the on-board 64KB of RAM could be memory mapped on a 64K
boundary anywhere in the full 24-bit S-100 address space. It had a
serial port (maybe 2, SIO or DART?) and a SASI port, the early
predecessor of SCSI.
It didn't have much in the way of software support for the slave mode,
so I haven't done anything with it. My ambition is to make it a Z80
co-processor card in a Concurrent DOS system 80286 system.

That's possible, but the probes themselves definitely are just wires with
clips (albeit a beautifully made version). I'll take a look this week.

Sorry, I've used one (once, briefly) but I don't have any docs apart from
what's in the Field Guide that Tim keeps on sunsite.

Actually, of 63 chips, only the 16 RAM chips, a 24-pin socket next to
the uP, and two 16-pin chips near the PIO and CTC chips are empty.

Do you have any schematics or other info on this board?

I think yes, you are the only person with a 5103 printer. I have a 5100
but no printer. Didn't know until your message that they even made one!
So I guess I don't need the ribbons...yet...
However--
I am interested in this --
(1) Computer Wharehouse Store catalog, Spring-Summer 1977. SWTPC! Imsai!
Kim-1! $1200 floppy drives! A slice from the "good old days" of the micro.
The pages are a bit yellow, but in good shape. The cover is also nice, but
the previous owner scribbled his name on the top.
-- if it's still available.
