Re: The elevator did it
I remember watching a guy[1] toggle in code on the front panel of an Altair 8800 that allowed it to play "Bicycle Built for Two" or "Fool On The Hill" over a transistor radio placed on top of it. Took the guy half an hour or so to program the machine. One of the people in attendance was heard to comment "that's probably the best use I've seen for a personal computer yet ... "[2]. It was late 1975 or early '76, at an early Homebrew Computer Club meeting.
