   I can tell you that. Atari used the FPU instructions in TOS, which is
obviously illegal. So no TOS ran on 68020's for years, and noone bothered
to write programs that where 68020 compatible. Hard times ahead for the TT.

   So, it's a lot easier to do it right on the Amiga, as the OS actually
allows us to use these nice fast CPU's.

   Actually, it's not _that_ many. But just one of these killer
instructions, and you're dead meat.
