Re: 65c816 in a IIc

For a direct processor swap to upgrade the 65C02 to a 65C816, a 65C802
will give you less grief. But again, you need the software to take
advantage of it. And maybe more importantly, you need a 65C802 -
extremely usefuly, just a bit rare.

The 14MHZ 65C02 will give you the boost for sure, with the same
software compatibility, but mess with everything else (video timing,
floppy timing etc). This is why we need a little extra logic on a
board, such as what the typical IIc accelerator cards provide, to make
it all go. Ive also noticed the high speed (14MHZ) 65C02's have a few
extra pins. These will need to be taken care of as well if your
intending on doing a direct swap.

Good luck.
