I remember those days.  At one point the PBS TV station in Boston was 
broadcasting a PCM simulcast of their FM station, but you needed a special
decoder to hear it.  I remember at least once recording a radio broadcast
of a program that would run on a Sinclair ZX81.  I got it to work but yikes,
it was tedious.

Actually, it was pretty damn clever, and when the only other alternative
was to type in a program, we jumped at the chance to try it.  The Tarbell
system that was used to encode data on a cassette tape, and though it was
capable of delivering up to 540 bytes/sec, most data was transferred at 
187 bytes/sec (1500 bits/sec, or 800 bits/inch of tape).  Loading programs
of any decent size took what felt like forever, and there was always the
possibility that the data wouldn't load if the tape was flaky.

Don't even need that step:
$ aplay /boot/vmlinuz-3.6.7-4.fc16.x86_64
Playing raw data '/boot/vmlinuz-3.6.7-4.fc16.x86_64' : Unsigned 8 bit, Rate 8000 Hz, Mono

Pure raw noise :)
