@mos_8502 hm, what are the capabilities of the eZ80's "something like an MMU"? I tried looking it up in the datasheet real quick but didn't find anything that I'd expect to be what you're referring to...

@mos_8502 hm, does either the Z80 or 6502 family support an MMU? I feel like a proper multi-tasking operating system would be hard to support otherwise...
