The very first example of this 'computer encoding' on vinyl that I'm 
aware of is on Isao Tomita's "The Planets" (1976) album of the Gustav 
Holst piece done up with various -- new at the time -- synthesizers.

When I first heard this in 1977 I was just getting my fingers into 
computing, but had no way to decode the message.  According to my 
memory, the liner notes specify that it is played into a certain 
cassette I/O interface on an Altair 8800 (or was it Imsai 8080?) 
one would find a special message.  I never had the hardware for that, 
nor have I thought much about it over the years.

I'm going to have to dig that album out (yes, I still have all of my 
old vinyl!) and confirm the target system, and then see what can be 
done to decode it with today's tools.

Hmmm.....yet another project on the list!

PS. If anyone is more determined than I am, let me know and I'll 
create a .WAV file of the section in question for your enjoyment.
