Definitely a flawed assumption. Each Mac has its own hardware peculularities
which must be accomodated in its specific version of ROM. F'rinstance, the
IIci has a weird memory map not found in a IIcx or SE30. It has built-in video,
while these machines don't. I'm sure that at least a few of these differences
manifest themselves as ROM code that would gag a non-IIci machine.
