Someone had discovered that if you put an AM radio on the console near the typewriter, and tuned to the low end of the AM dial, you could hear all sorts of interesting noises. We never did figure out what caused them, but one guy wrote a program that would play songs, and after a while, you could tell what the computer was doing by the sounds it was making. It was lots of fun to be able to tell innocent bystanders "the printer will start in five seconds", and then have it happen. Dani Eder / Boeing / ssc-vax!eder / Ad Astra!(To the Stars!)
