The posession of accesible Mac ROMs or a software copy of them (i.e. loadable
into RAM) is all that stands between someone with a non-Mac 68000-series-based
machine and Mac emulation.  As far as I understand, some owners of the A-Max II
Mac emulator on the Amiga, which requires either the ROMs or a software copy
of them, have software copies of the Mac ROMs.  I believe Apple's license for
the ROMs makes it illegal to copy their contents into software...
