There was also the fun of setting a radio in specific places on the main control panel and listen to the music it played. Somewhat better than the printer banging away as you'd get actual tones to play.
An AM radio in the vicinity of an IBM 360/30 and 360/40 would definitely sing to you at the proper frequency. I was a third-shift operator in a former life, and a properly-tuned AM radio would let you know clearly when the machine was idle, and with a little practice, a rough idea of what it was doing :-) The machine cycle time of a 360/30 was 1 microsecond (fact), placing much of the RF noise in the AM band (at least that was my guess).
