Unfortunately the increased code size could slow the whole of Steem down
quite a bit, plus all the checks we would need for what type of processor is
being used (24-bit or 32-bit addresses, that would have to be checked
everywhere).

Well the later Amigas were more popular than the later STs, so there is more
software available and more people with a reason to want them. I'm not sure
but I would think it would be easier to implement different processors in an
emulator that isn't trying to be 100% cycle accurate too.
Best wishes,
Russ
