Here's a question I'm curious about:

What can a consistently too low/high-voltage wall socket (100/140
volts instead of 120, for instance) cause a PC power supply to do to
the rest of the computer?  How can erratic frequency control change
the supply, and in turn, affect the computer?

Someone in comp.sys.mac has had 10 separate problems with their Mac/SE
(5 disk drives, 2 system boards, 2 keyboards, 1 mouse).  Many users
have no problems at all.  I'm curious if the power outlet in their
dorm room might be a partial culprit.
