If you're going track-by-track, probably a couple hundred K is more
than enough. But holding a complete 8" DSHD image runs to something
like 6MB if you hang onto the whole histogram.
I think you'd definitely want to have enough storage to hold a
complete image--it'd make copying much simpler, no? Besides, a few
megabytes of RAM is nothing nowadays.
I don't know, what's a couple of hundred KB of
memory, a CPU (say a Z80 for
sake of argument), a bit of ROM, and a serial interface chip, plus a bit of
glue logic?
Probably use something a bit more common, say an ARM? Not that I
have anything against a Z80 (or Z180, or EZ80). Just that extra
horsepower can be very nice, even if you don't need it right away.
