Ditto for me!  The campus power was flickering around back a month or
so ago, and I was sitting at the machine at the time.  There was no
change in display intensity or anything, and they were enough to make
all the lights in the room flash.  My thinking was that the power
supply NeXT has is more lenient since it can automatically configure
for 120/220?/240 voltage.  Since then I could swear I've seen my
monitor *flash* like it got powered off-on really fast.  Very weird.

However, I would like to be able to check the 'cleanness' of the power
in a old house I'll be living in for the next year or so.  Does anyone
know of a way to check the power for excessive noise or such?  I'm no
EE, so if my thinking is all bunk, a kind word would be appreciated!
