Show a kid a 3.5″ floppy disk today, and he might look at you in quizzically. Show him a 5.25″ floppy, and he’ll think you showed him some kind of ancient talisman. But in the days before floppies, programs were typically distributed as audio on cassettes. (My recollection of programs on my Atari was that they used 600 bps.) But what I don’t remember (and hadn’t seen before) was that people actually distributed programs as audio tracks on old vinyl LPs (themselves a relic from the past).
