FWIW, here's a thermography (hope the link works) of the B-cache section
of the KA-675 after being powered up for ca. 30 mins:

Note that the rightmost chip just below the CPU heatsink has a pin that's
ca. 2 degrees warmer than the others. I don't know if that says anything,
but it *is* reproducible. Maybe I should start with that one.
I can't really make it out on the image but if it is just one pin that is
hot, maybe there is nothing more complicated wrong than a bad solder joint
at that pin, particularly if it is a power or ground pin.
