I think the current Nintendo uses a 6502 (or 65C02). A new Nintendo will be comming out soon. I think it is allready out in Japan. This one might use the 65816. The Saga Genesis might use the 65816 now. Also, the one from NEC uses a 68000. (I believe?) Mike.

Nintendo IS an 8-bit machine. It can't be using a 65816.

I kinda doubt it because they advertise NEC's machine as "Turbo Grafix 16", because of the 16 bit CPU. The 68000 is a 32 bit CPU.

Actualy, the 68000 is a 16-bit processor, and the 68020 and above are 32-bit. the 68000 are found on the Mac+, the oldest mac model available which is a 16-bit machine..

Well, if you want to get technical, a 68000 is a 16/32 bit CPU. It has a 16bit data bus, and a 32bit address bus.

I don't know what you mean by such labels as "16-bit processor". There are numerous data paths in a modern computer, not all of them having the same width. Motorola advertises the M68000 as a "16/32-bit microprocessor". For a general-register architecture such as the M68000, it makes some sense to use the data register width as the bit size of the "processor"; from that point of view the M68000 is a 32-bit machine.

>> >>I think the current Nintendo uses a 6502 (or 65C02).... >> The recent "Rash" of Nintendo articles seem to be a little out of place. The last time I checked this was an Apple Newsgroup! Did someone change the newsgroup when I wasn't looking?? I think there should be a new newsgroup for Nintendo BSing. In the mean time let's not forget why "WE" subscribe to this newsgroup. I know there are other people out there that feel the same way that I do, so let's lighten up on the Nintendo crap and stick to Apple related material. Steve (flame on)

The 68000 is a 16/32 bit cpu because it has a 32 bit arithmatic/logic unit and 32 bit internal data paths - but only a 16 data bus to the outside world. The 65816 and 65802 are 8/16 bit CPUs: 16 bit arithnatic/logic unit and 16 bit internal data paths; with 8 bit data bus to the outside world. The 65C02 and 6502 are straight 8 bit CPUs. - Ron Wilson
