Mr SQL Posted September 18, 2015 Share Posted September 18, 2015 Awesome article! Liked the detail on and custom version for Nintendo adding 22 memory mapped registers and on-chip oscillators for sound in lieu of BCD, I thought it had a straight 6502 like the other 8-bits; are they possibly referring to the 16-bit version for the SNES?

No. The NES has a 6502-like core with additional functions. http://wiki.nesdev.com/w/index.php/CPU 1 Quote Link to comment Share on other sites More sharing options...
jdgabbard Posted September 22, 2015 Share Posted September 22, 2015 I found that the book "On the Edge: the Spectacular Rise and Fall of Commodore" has a superb couple of chapters on the 6502. It's a great read. I'll be checking this out when I have a few minutes to sit down with it. 2 Quote Link to comment Share on other sites More sharing options...
