Hello,
I'm looking for an interface panel used by the ISI monochrome workstations
for attatching to the back of the card cage. The one I have has some faulty
coax connectors on it.
It's an odd looking little board with two DB25's on it. I've drawn a picture
of it below so you can get a better idea of what I'm talking about. The top
DB25 (A) has three holes in it to pass through three mini coax connectors, but
only the center hole is used (the other two are used by color workstation).
The bottom DB25 is used to connect an optional alternate console (character
based) to.

On the back you'll find you'll find two connectors, one (C) is used to route
two coax cables (used for Horz. and Vert Sync) and the other (D) is used to
route the serial ports to and from the CPU card. There's a third coax cable
running from the top DB25 (A) to the GIP card, this is used to route the act-
ual video signal.

If anyone out there has one of these panels from an ISI machine please contact
me. I would be willing to pay a small price for one. I don't know how much
they cost, but we can negotiate a price.
BTW, I think the interface panel from an ISI color workstation would also work.
Please reply by mail to pascal@leland.stanford.edu.
