The 65C02 is a slightly upgraded version of the popular and venerable 6502microprocessor. The 65C02 shared its predecessor's 8-bitinstruction set architecture and 16-bit memory addressing.
The 65C02 added a small number of documented opcodes and, significantly, fixed the irksome 'indirect jump page wrap bug' that caused fits for so many budding assembly languageprogrammers.
The WDC 65C028-bit CPU is an upgraded CMOS version of the popular and venerable MOS Technology 6502 microprocessor, the redesign being made by Bill Mensch of the WesternDesignCenter (WDC).
The 65C02 was second-sourced by NCR, GTE, Rockwell, Synertek and Sanyo.
The 65C02 shared its predecessor's 8-bitinstruction set architecture and 16-bit memory addressing, but added a small number of documented opcodes and, significantly, fixed the irksome "indirect jump page wrap bug" that caused fits for so many budding assembly language programmers.
