z80 timing... 6502 timing

Since we've not seen any code for the 6502 yet, this may not be a problem,
but since Apple didn't exactly make it easy to exchange diskettes with other
systems, how would you propose to transfer a file, binary or otherwise
between systems? Though I haven't gotten into it, I figured on
cross-assembling from a PC to a PROM. That makes it easy for me, but how
will others do it?

It's enough of a problem transferring files from, say, a CP/M box running a
Z-80, since PC's don't read 8" disks.

How should this be dealt with?
