z80 timing... 6502 timing - test-drb@ccmp.vtda.org

22 Apr 1999

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?

Some third party, can run the

Nice, but with these things, like internas of the system for input/output,
binary and similarities, you tie again all down to a single system to
use - we loose the idea of a cross platform competition where only basic
processor features are measured (see also the subject). 
I don't see what you mean. By setting some basic format for the file
structure you make it PORTABLE, not restricted. Each target system then can
read the common format and arrange it however is best suited to that target
system prior to execution of code.
