One other thing I have done is to emulate the music

single pole RC lowpass filter hooked up to the S-100 INT* line. The
"MUSIC" program would take a score and compile it into a program to
toggle the INT line to produce polyphonic music -- although the notes
aren't very well tempered as they get higher in frequency. It is pretty
impressive that it works as well as it does:

I recently upgraded PC's and now my own emulator doesn't run right and
the sound comes out only when I'm using the debugger. I guess it is
about to time spin a revision on the emulator.
Very cool! Did you record this from the emulator or from an actual
Sol-20? It sounds as good as what the Apple ][ could produce, which I
suppose makes sense since it's generating sound using the same principal.
How do I load and play the sound files?
