When I first learned programming in high school, our math department had
a HP-2114B 8k machine which booted ala the front panel.  One of the local
guru's programmed the computer to play Bach and other classical tunes on
a AM radio.  The program became so popular, a radio became a permanent
hardware addition!  

This same person also found that by switching on and off the 2748B's
motor, he was able to 'play' the same songs on the tape reader.

I began to experiment with writing computer games which would produce
sound effects.  One game, star trek, would produce phaser, photon torpedo, 
and red alert signals on the radio.
