I'm more familiar > with the 682[01] but this one is nicer ;) Mmmm - very interesting stuff - I used the 6522 as well as the 6821 on many self build 6502 and 68k based systems. Usually a single 6522 to get system timers and then 6821 for firther GPIO. Since it's only a small step to the 6526: can we expect a C64 port soon ;-) But honestly - I wasn't aware that a modern computer system still uses them. -- B.Walter BWCT http://www.bwct.de bernd@bwct.de info@bwct.de
