- I admit, it won't be easy. But what do you think is trickier, an PPC 68000 emulator or a multiprocessor
- adaptation of an OS that has always been multi-_tasking_ from the beginning? I dunno. We'll probably
- go multi-processor in the future anyway.
-
- A real problem would be that you have to keep two OS's in memory. Although this would increase the
- compatibility (you could use an old OS3.1 version) this *is* a lot of overhead.
-
- As far as the price is concerned: you can afford to buy an A4000 with a CPU already in it
- just to replace it with a better one, can't you? Then why not this configuration?
-
- Anyway, it's just an idea.
