one thing I LOVE about early home microcomputers is how ingenious storing data as an analogue stream was, like I'm aware of cassette tapes, flexi disc records coming free with magazines, and radio broadcasts as ways of distributing data. I'll admit, DOS on a record is a new one.

Also what's cool is because it just cares about the audio and not where it's coming from, you can easily load programs onto your old computers with an MP3 played off a smartphone, which is so fucking cool.
