In the 70's, there was an old DECUS (Digital Equipment Computer Users' Society) program that could play four part tunes on a transistor radio placed near the console of a DEC PDP-8/I minicomputer. It didn't matter what channel the radio was tuned to. I always assumed it was something to do with the ferrite cores (each bit visible to the eye) making up the memory. One of the tunes that came with the package was Air on a G String, in the manner of Walter/Wendy Carlos's Switched on Bach. The fidelity was not bad.
