I have a ][ plus that I bought in 1990 or so. Obviously used :)Last night I have noticed that the CPU is not the regular 6502, not even a 65C02 but a W65C802 - a 16 bit chip in 6502 pin compatible case.So the question I have is this: is there any software to take advantage of it? I doubt it, 'cause I have never heared of such a mod before. And while we are at it what software benefits from the extra instructions in the 65C02? Apart from the 2c firmware and such.
I recall a couple. HyperC has a patch which uses the 16 bit to speed up certain functions. I think later Merlin assemblers support this CPU too. There may be other assemblers as well. However, software in general treat it as a 6502/65c02.
IMHO, this should have been the next upgrade for 8 bit II's. Cheers, Mike T.
