6502

141 bytes added, 5 September
/* Oddities */
* The 65C02 fixed multiple bugs of the original NMOS 6502, but also removed access to all illegal instructions. And it added some extra instructions. In fact, there are multiple implementations of the 65C02 (WDC 65C02, WDC 65C02S, Rockwell R65C02, CSG 65CE02, ...), each with its own variant of the instruction set.
 
* The 6502C is a regular NMOS 6502 with an additional HALT pin, used in Atari 8-bit computer range. Not to be confused with the CMOS 65C02.
