I have an LP, "Electronic Music from the University of Illinois" (1967 or
If I recall, they used the U of I's ILLIAC IV in the recording.
It's somewhat interesting but the electronic parts of it are sometimes hard
to discern :). Looks like someone's digitized it here:
I digitized an 45 of music generated by an Orchestra-80 (TRS-80 4-channel
synth), it's called "Classical Mosquito!" -- you can grab it from here:
As an aside, I've been (slowly) working on emulating Ted Kaehler's organ
keyboard / FM synth for the Xerox Alto (c. 1974) in ContrAlto. I have just
enough technical information and code listings to make it possible, but
there's just enough information missing to make it difficult...
