The only machine I ever heard rumors of the cause being traced down on (the
Digilog Microterm II), it turned out to be electrical noise being picked up
by the amplifier for the speaker.

It's actually quite nifty; you can get a good feel for what the machine's
doing just by listening. For example, you can tell whether your program's
stuck in an infinite loop or actually doing loops.

I have a friend that actually went out of his way to ensure that the
speaker amplifier in one of his new designs would have plenty of opportunity
to pick up noise to duplicate this; he ran the input wires all over just
for this reason.
