I actually
worked out the approximate holding capacity of an LP once - I
think I assumed digital->audo modulation to be v.34 or v.42 - something like
that.
Actually, I once saw an ad for a UK magazine which had a multi-format
flexidisc insteqad of a cover tape. Why not?
I seem to recall way back when seeing magazines with "floppy" plastic
records in them that you'd play into your computers tape jack to load the
software. ISTR something for the TRS-80 Model I and the KIM-1....
