Well, I'm sure that your correct in that most Z80s only have <= 64k, but
there are some exceptions, such as the TRS-80 Model IV and the Commodore

Of course, there's no reason you can't go ahead and pick a bank switching
scheme, my point is simply that I doubt it will be compatable with other
machines that don't happen to use the same scheme.
