***** Nobody knows the lines I've eaten - song title *****

It's about time I make another comment on the jolly black power supplies. A
couple of days ago, my TOS ROM(s) blew. I deduced this from the fact that
all went well with the old chips replaced. It took a week for the new chips
to stop working. But I gather that these ROMs are really Eproms which happen to
be opaque, which makes them somewhat vulnerable to the dreaded power supply
surge.
   Now the people who told me about the power supply scandal have consequently
informed me that a very simple test will determine whether the power supply
is of the evil variety, without having to wait for disaster to visit. It
seems that with zero load, a humble voltmeter will demonstrate the true
nature of the thing. So this would indicate that the same fault that causes
sub-optimal start-up characteristics also causes inappropriate response to
zero load. If so, this would help prevent a lot of indecision about what to
do with "the black power supplies".
