The problem may be insufficient cooling. Voltage is reduced on the
unibus when the temperature of the processor exceeds a set limit.
Unfortunately, nothing tells you that is what's happening. There is
no way diagnostics will catch this one. An easy test would be to direct
more cool air to the machine and see if that clears up the problem.
