Well more Sun 3's than I  expected.   Does anyone use
them in regular day to day use?  I'm thinking of leaving mine on,
if I can find something useful to do with them (aside from playing hunt...
8-) )

Yes, the fault is on the CPU board.   Very interesting idea... have to see
if I could find
a spare VME connector (don't have any trashed VME card cages.... just have
3 slot ones both of which work... just don't have access to the board
without taking
them out.... even with the skins off..   I have some junk PC power

I will contact Peter to see if he has a map of the chip to address.. thanks
for the
