I would like to pass along here that a 65C02 (i.e. an 8MHz Zip Chip) works just
fine in my final revision II+ (revision 7 if memory serves). I saw recently that
a cached 80486 processor that for 80286 and 80386 sockets now exists, but is
much to expensive (better off to just upgrade the motherboard at the current
cost). I wish somebody would produce a cached fast Z-80 processor for use on
CP/M boards (and other embedded Z-80 applications). 8-)
