Strongly seconded, along with the Hitachi 6309. But the latter is hard to source. 6809 would be just fine. I keep a Color Computer 3, which has the 6809 stock, just because it's so much fun to program. Best of the 8 bit chips, if you ask me. You know, when David gets done with this system, it's not a big stretch to make one with a 6809. Maybe someone will. The 6502 was used because the Commodore kernel can be reused, or something like it can. It's not a total rewrite and that gets the project somewhere useful and familiar quickly. I don't blame 'em, and the 6502 is fun too. I also suspect a rewrite of those components, BASIC, etc... in 6809 would end up smaller, faster and more feature rich too. Big project though.
