Should be readable. There was a kit I remember from a few years ago to
use a `normal' cassette machine with the VIC/C64. The only difference
with the Commodore version was a fixed record/replay level. I can find
out the VIC/C64 pinout for the cassette port if you like.

These also used a proprietry records, but I imagine that what I said
for Commodore also applies here.

Not much point? How much was available on tape?

I think the ZX80/81/Spectrum used the same encoding.
