Hello,
    I was just working on my Solbourne 5/600, and I decided to take a look
at its VME boards. Unfortunatly, the Solbourne Shack webpage offers little
information on identifying boards, and the few images of VME boards are no
longer availible. So here are some of the boards I am curious about. The
first board is labled Heurikon on both of its tabs, and has the following
lables over its connectors: Serial, FPI, FMS 1 2 3 4 (over a set of LEDs),
reset, and SCSI. It seems to be a Motorola M68000 board of some sort as it
has two small chips on it which are labled MC68000R10 and MC68450RC10, with
further markings below them. Board number two is a 6U VME card with 4 large
AMD branded chips on it, and two sub boards which lie flat on the VME card,
it has a 10 pin plug on the back (just pins, it is 5x2) which extends from a
daughter card which has an AMD chip labled Am29000 - 16GC, a minidin
connector, 2 small LEDs, and then 4 large bulb like objects, which are
alternatingly black, and red, the connectors for those are labled AT&T. I
then have 4 boards which are covered with chips, the majority of which are
TI or Philips (?) branded. The ones which are in sockets have MX07?? or
MX7?? (with ? representing any number) on them. These boards have no
external connectors, nor back plates. Finally, I have a board with the
Solbourne logo on one tab, and MUX on the other, and it then has 3 50 pin
cables along the rear. It seems highly likely to me that this is a Xylogics
781 16-port MUX.
    Anyone know what these cards are?
