Wow! All I can think of is some high voltage going on in there, like
the flyback transformer in an old tube TV. I never heard the one I
worked on, like you say probably because of all the machine noise in the
tape room.

Ahh, yes. The slow refresh rate of the 3290. I don't know about yours, but we
could not only watch the 3290 repaint the screen top to bottom, but we could
also hear it repaint. Kind of a quiet rattling or rapid clicking sound during
a refresh. Couldn't hear it in the machine room, but it was definitely audible
in an office setting.
