6502
,/* Chip Variants */
* The 6510 CPU, used in the [[Commodore 64]], is a 6502 with an additional AEC pin that puts the bus in high impedance mode. It also includes a 6-bit I/O port that occupies addresses 0 and 1.
* The disk drive of the Commodore 64 has its own 6502 processor that acts as a floppy disk controller (FDC) and as a Disk Operating System disk operating system (DOS) processor. It can also be used as a general coprocessor for the main system.
* The 6502C used in [[Atari 8-bit]] computer range, adds an additional HALT pin. The 6502C is otherwise a regular NMOS 6502, not to be confused with the CMOS 65C02.
