O.K, What is needed now, is for someone to write a PPC emulator for the 680X0 processor, it may not be fast, but it could be usable.


It would be in no way usable... unless you like slideshows of desktops...

There are many people who are quite happy with the speed of their 7mhz 68000, there could be people with 060's who would be happy to emulate a slow PPC if it means their classic amiga can run new software written for the PPC.


You don't realised that the speed of an old RISC architecture like the PPC comes from taking advantage of Hardware features and limiting the ISA to avoid the limitations of the hardware.

There is no way one could run a PPC emulator on a 68k machine at any speed greater than one frame every 5 seconds... I dread to think how slow the MMU emulation would be...

If we want to run OS4 on a pc we would use pearpc or similar, would the pc also need to run windows or linux?


Yes... or MacOS X...

PearPC is rather quick, though obviously pointless, on my MacBook Pro...
