I know we've had discussions about I/O port assignments, but just
realized that if we ever do the Z180 board we will need to avoid I/O
address in the 00-3F range. The Z180 internal hardware will need to be
accessed in that range (since 40-7F, 80-BF, and C0-FF already have
H89/H8 devices well established). So, we'll want to plan for that going
forward. The H8-512K-MMU board is at 00, but that one is OK since the
Z180 won't use that board. So, any boards that won't/can't be used with
the Z180 could be in that range.
