Hi,
I have an old CRDS Universe 68/27 system that will no longer boot. The firmware
diagnostic claims that the MMU circuitry on the CPU board is bad. This is the early model
CPU board known as a "CP-68". The Motorola part number for the board is 76430347. Motorola
wants $568 to exchange the board for a good one, which is a bit much to repair a system
that I got for nothing (well, actually I DID have to carry it down 3 flights of stairs :-)).
CRDS will not support the system since the hardware was originally manufactured by Motorola
and since Motorola wants more than I'm willing to pay for a replacement board, my only
remaining alternative is to try to fix the system myself.
If . . .
1) you have a similar system which is operationsl that you would be willing to part with
for a little (< $100) money, or
2) you have a similar system that has a good CPU board but has died for other reasons, or
3) you have schematics for the system (especially the CPU board) that you would be
willing to share,
. . . I would like to hear from you. You can reach me through any of the paths outlined in
my .signature below.
Thanks for listening.
