Hi All,
Early days still, but I've built two different CPU replacements for the C64:
one internal and one which fits into the expansion slot. Neither at the
moment offers memory mapping (that is port $0000/$0001) my main interest was
to sort out the VIC etc.
I'm aware that there are a number of assemblers / cross-assemblers out
there.... DreaMon, Sirus, ElCheapo, Jammon... which of these will allow
writing of 65816 test code on a 65816 "C64" machine without $0000/0001 and
without SuperRAM?
Cheers,
Nick
BTW: ultimate purpose is a simple CPU replacement that would support testing
of apps like WiNGs before having decide to buy a SuperCPU. So the adaptor
may end up supporting extra RAM, but not offer 20MHz...
