You'll note that Nintendo also produced best-in-class graphics and sound capabilities for a handheld in the Game Boy, using very similar graphics and sound hardware, but a completely different CPU (one based on the Z80). | |

In fact, the 6520 was a copy of the earlier Motorola 6820/6281 PIA, and the 6522 (and the RIOT, RRIOT, 6526, and many others) all used that same core PIA functionality, working in the same way. | |
| May 14, 2023 at 2:26 | comment | added | cjs | Actually the NES is not a good example here; it was practically unknown in Japan. It was used anyway because a) Ricoh lacked a manufacturing license for the far more popular Z80, and b) Yamauchi felt that using such a processor that nobody else used would give them a competitive advantage.
