Emulating an Atari was rather simple (except for the CPU),and was
later done in atleast 2 commercial products (for the Amiga), namely
Chameleon and Medusa.These emus did run TOS/GEM and even
some of the games. It was possible due to the fact that the ST was a
rather simple design, where the CPU would most of the stuff itself, and the
rest was more or less standard parts which didn't do much themself.
Similar to the 68k-Macs,which were featured in a whole bunch of emus
both on ST and Amiga.
Emualting an Amiga does need more, because of it's DMA-design, and
custom-chips runnning half the system without bothering the CPU.
Just look at how long it took till UAE could just boot into a Workbench,
and how much CPU-power it needed on the host side.
The only non-Amiga running AOS was the Draco, which can only run
OS3.x, needs to patch it in RAM before starting, and still has 2 orginal
Amiga-CIA chips onboard (needed for timers used in exec-task-scheduling).
