There is a little discrepency in the CPU identification of the Nintendo Entertainment System.

The CPU in question is the Ricoh 2A03 that's used in the NES. The 2A03 is a variant of the 6502 CPU which was designed by MOS Technologies, not Motorola.

The only thing that MOS and Motorola have in common was that MOS was started by former Motorola employees.

For a little more trivia, the Commodore 64 computer uses the MOS 6510 CPU, which is directly based on the MOS 6502. Furthermore, in the early 1980s, Commodore Business Machines purchased MOS. Essentially, the NES core runs on Commodore technology (although the 6502 was developed in the late 1970s well before CBM's acquisition of MOS). - Reinhart

Oh, the disk drive is another interesting device. It was considered an "intelligent" device because it had its own computer onboard and worked with the C64 computer. In addition, the main CPU in the disk drive was a 6502. - Reinhart
