- Well there is gigamem, for virtual memory [ nice but really belongs in the
- core of the os, but does the job for graphical conversion stuff ]
- And there will be emplant that uses it to multitask the amiga os with the
- mac os, or allow mac os have full control and have pmmu.
- Well how about running os 2.04 rom and then setcpu'ing to 1.3 or 1.2.
- Or if you have 3.0 rom you could do that down the line.
- This is of some importance since you can't zkick down from 2.0+.
- And the price diff is really not there. Hopefully someday cbm will have
- support for mmu in the os. Maybe something like virtual amigas, where
- all things can multitask and think that it is singular, ie two games
- that don't multitask could multitask.

- Why not get the a1200 though? slightly more but you get graphics accelerated.
- As opposed to only fast ram speed up.
