Source for 65C802 CPU


Recommended Posts

With tf_hh's SCCC it would be possible to put a 65C802 (or 65C02) in a PAL 800. Are there any sources to still get the 65C802 or is it too late?

The only place you'll find one is 2nd hand.

Production stopped within a couple years after it was introduced.

I never understood why it wasn't more popular.

Lack of support I suppose.


There is a supposedly simple way to plug a 65c816 into a 6502 socket mentioned in another thread.

It will run everything a 65C802 will.

There's also the Antonia 4MB RAM Expansion that has a 65816 on board as well as more RAM.

There are faster 65816 boards out there as well, but the commercial options aren't as cheap as the "simple way".

The main side effect of the "one-wire" 816 mod is that Incognito BIOS forgets its settings. The time and date are always correct, but BIOS settings are forgotten on power loss.


I had no noticeable problems other than that, but I reverted back to the 802 so as to not take chances with my BBS machine crashing.
