No, it's not false at all. It can be done, and it can be done _easily_. If you think otherwise, you're quite wrong. The speed of the chips in situ is due to the incoming clock. A faster chip coul dbe made (again, _easily_) at the current rates by continuing to clock it slowly. 8520's are _nothing_ with regard to complexity – if CBM didn't doc them, well, there you go, eh? That's certainly a problem, but not one that is killer. There _are_ docs for older chips that are ___extremely___ similar (MOS 6522 VIA's come to mind immediately… similar right down to the bizzarre way the flags are handled and the wacko timers work – and they're very well doc'ed, too) and I wouldn't be the least surprised if a lot of the "missing" info would be found right in other chip docs. I can't say that "using C= internal resources" fills me with a vision of incredible power turned on a problem. Quite the contrary. I see no reason at all why this would be a hard task, simply given the $$$ to use the proper resources to get it done. –Ben …via AutoPilot
