Going back a lot of years now, I remember one friend programming an S-100 bus computer to play "music" through an AM radio by using the RF noise generated by various instruction sequences. Like they say about the dancing bear, it isn't how well he dances, it is that he dances at all.

He never did succeed in making the music and the display from a Cromenco Dazzler video work together which is what he was attempting to do.
