Well yes! @kempa.com/ they have the story

One strategy that major record companies have been employing lately to deter downloading is adding bonus computer content to new CD releases. I recently discovered that this technique is not unique to CD’s, but had in fact been practiced in the vinyl era as well. That’s right: there were a handful of records released in the late 70′s and early 80′s that contained computer programs as part of the audio. This is totally insane, and totally great.

This is actually really interesting (well if your into that sort of thing).

I remember that my first computer the Commodore 64 came with a cassette deck and that deck played ordinary cassette tapes:

Someone in Østerbro was broadcasting computer programmes on local radio and we actually managed to tape that on a ghettoblaster and then play the game.

I wonder what others were thinking tuning in to that white noise :D
