SCSI MCA cards are so common in the systems I find I don't bother to keep

there's plenty to choose from, scsi with or without cache, or you can even
get some of the better scsi controllers out of the 9595 models. I have
several non IBM MCA SCSI adaptors which Ive installed in some pre-existing
SCSI-equipped PS2s just so I have a standard external connector to work with.
Those IBM external cables are getting hard to find.

Not to mention that designing and producing a very low production board
such as the ethernet board for the IIGS surely isn't cheap. The volume just
isn't there to drive the price down. Michael Holley has finished the design
of a new floppy controller for the SS-50 bus machines and has a few examples
running and is testing them, but after paying for the fabrication of the PCB
and the various chips and other parts, the finished board is costing nearly
$100 in parts alone. I would imagine most on this list would balk at paying
that much but it certainly would fill a void if you were in desperate need
of a new floppy controller to get a machine up.

The Convergent (mini-engine, mini-frame was a nickname I believe) was a
modular computer made up so small boxes locked together. I think it was sold
mostly to the Government and the military.
The first CPU module (B25) was an Intel 80186 processor. As technology grew
they made units with 286 (B28) and 386 (B36) processors. I believe they ran a
proprietary OS.
I have the module description manual buried somewhere in storage since the
move.
They had single and dual floppies, single and dual HDs of several sizes, tape
drives, mono & color graphics, even a PC emulator module. The module name is
usually on the front.
All of the power supplies were external 36 V with RJ type cables. They were
different power capacities depending on the draw required by the module.
I always thought they were cute but never got one up and running. Monitors
and graphic modules need to match. You need the proprietary keyboard. They
are password protected.

See below, from austin.forsale a few days ago. If anybody needs/wants some
of this, for shipping, I can try to arrange a pickup this weekend and ship
next week, as I'll be in Austin on the weekend. Contact T. S. Murphy first
to make sure it's still there, though. Curt, I suggest items 15. and 16.,
assuming they work together. BTW, what's the story with the kilobuck worth
of NeXTs? I think I committed for one of them and have not heard from you
yet.

I suspect it's possible, but I've left mine alone and instead
sought other model Silent 700s for use as serial terminals.
One of my 707s has the coupler; I'll see if I can't determine
the pinout for you, but IIRC, the connector carries audio
only.

Does a KA10 have blinkenlights or does it suck?

I have some DX50 processor complexes, and a couple type 4 that run pentium

The p90 came in the server500 series. Theoretically, you can swap any CPU
complex between the 85,90,95 and server 500 series machines. All you have to
do is run the correct ref disk for the type complex you are using. (type
1,2,3 or 4)
No, not Concurrent. Close though.. You're thinking "Convergent". Concurrent
makes minicomputers, never made anything small like the Convergent... Those
are neat little systems : )

The P400 was the last machine (well, maybe the 450?) that
had a front panel. It was an interesting bump-out design,
but wasn't really very cool looking, when compared to an
Eclipse, or a KI-10, or hell, even a KL-10.
My 2455 has a virtual control panel like the 750 did. If
I had a real front panel, the damned thing might be running
right now.
