65C816 Processor Card

[Alan Cox]

This is a 65C816 processor card that is designed for RC2014 so uses 16bit addressing. It is meant to drop into any existing 65C02 based system and work transparently. That actually seems to work out except for Fuzix which is too smart and finding a 65C816 tries to do things that assume 24bit flat addressing.

There isn't any direct performance gain - a 65C816 running 65C02 code is exactly the same speed as a 65C02 but it does give you access to the much nicer 16bit modes of the processor.

Could you add pdf schematic?

I’m too lazy to install kicad again.
