Hi,
a friend of mine sent me an DEC Server 300 which he saved from the
dumpster. There is a triangle in the bottom that some sharp metall edge
must have made. This hit broke a 300mil 24pin DIL chip in the inside that
I've never worked on one of thsse, but I'll take a guess...
Is there an AM7990 (40 pin DIL) on the board? If so, my first guess is
that this is an AM7992. See if the pins match up.
