   I don't see why you couldn't just write your programs on the Amiga.  After
all, 68000 assembly is 68000 assembly.  I can't imagine that an introductory
assembly language class will get so involved in machine-specifics that porting
from one machine to another would be terribly difficult.  Write a machine
specific subroutine to access every OS routine you need for each machine,
and use those subroutines in your code.  I did something like this for a
graphics class where the final code had to run on a Mac.  It isn't tough
if you think it through, and it is good experience.
 
   To help you along, you might want to take a look at a book titled
"Assembly Language Programming for the 68000 Family" by Thomas P. Skinner,
1988, John Wiley & Sons, ISBN 0 471-85357-7.  It covers 68000 assembly
using the Amiga, the ST, and the Mac.  It includes basic startup code and
I/O routines for all three machines, aside from this, all of the code is
identical for each machine.
