Curiously, we are suffering exactly the same problem as I write. We had a
similar fault a year ago and after testing all the boards in the STE bus,
deduced that there was a fault with the power supply. Superfically it was
working and providing 5v but apparently when under full load it was dipping
which caused the CPU to crash intermittantly.
We had the power supply fixed by Daren Electronics (who supply them to
MicroMass) for a bargain £25 and everything worked fine until last week,
when the same fault reappeared. So, suspicious that the repaired power
supply is playing up again I am awaiting to try out a new one ordered last
week. However I am very intrigued by the comments by Harro and Bruce that
the CPU battery may be at fault (I confess I didn't know there was one!). I
am just going down to the lab to investigate as soon as I hit the send
button....
Either way, I'll let you know whether the power supply is the cause of our
problem or not.
