Heh. I think it would be faster to list the similarities.
There is very few. the 68k is a 16/32 bit processor (32 bit registers and
operations, but only 16 bit databus)
while the z80 is 8 bit. The 68k has a lot more registers, and a lot more
advanced adressing modes, and more instructions, which execute faster.
The standard asm is very different too, among other things the destination
and source are switched.
so ld a,$10 becomes move.b $10,d0...
You can get the Programmers Manual for the 68000 from my site:
http://alh.dhs.org/ti89/
and compare yourself.
