Well, I believe an '020 has most of the same instructions (if not all of them)
of the 68030, but it seems to require an external MMU (the 6551).  The
68030 has this MMU built-in.  Be sure when you buy the card that it
comes with a math coprocessor, because having an accelerator card
without one is not too good of a thing to do (math coprocessors take
over integer functions so the 680x0 can do other things!).  By the way,
a 68040 is a processor that contains the CPU, MMU and the math
coprocessor!  By putting all of this stuff together you get the
opportunity for a good speed increase.
