I seem to remember that the reason a person can't add a MMU to the LC
is because the MMU needs to sit between the memory and processor, so that
it can perform the logical to physical address translations.  Since Apple
didn't leave a sockett available for this, since the processor is soldered to
the board, and since the address lines go straight to the memory array, it
would be difficult to add a MMU.

This is just my understanding, and could be totaly wrong :)
