Which connector are you referring to? The KA630 and
KA65x both use the
same console bulkhead, and in turn use the same two cables that connect
it. The KA630 and KA65x do of course use different memory boards, but the
ribbon cable that connects them is the same. Those are the only 3
connectors that I can think of offhand, except for the Q/CD bus
connectors...
The over-the-top connector in question is the one used to connect
the memory cards to the CPU; sometimes also called the PMI connector.
The KA630 one and the KA650 one(s) are different. The KA630 one
does have some issue in a KA650 system, but I don't know exactly what
the problem is. IIRC the KA630 one has three connectors (two mem boards
max) so a four connector one (three memory boards) would be a KA65x one.
(I don't have part numbers and a quick google didn't help).
This may, of course, have nothing to do with your actual problem.
Well, *none* of the memory boards are faulty :)
OK - if you know they work, that's different.
For some reason, they seem to not be getting clean
power, so they are not
working properly. I won't know for sure until I get my scope probes, but I
expect to see lots of noise on the power supply output that happens to
power most of the chips on those boards.
