Ehm, do you know anything about Operating System
generations? Bah, I don't think you do... If you did you
wouldn't even mention that...
As for the AmigaOS running on PPC part, MorphOS
was just an emulator back then.... It just emulated
the 68k. So yes, it did run AmigaOS 68k on PPC in
the year 2000, up to version 0.4. It just patched parts
of the OS to make it run on the emulator without
the need to emulate the custom chipset.
