Western Design Center 65C02

The 65C02 is a slightly upgraded version of the popular and venerable 6502 microprocessor. The 65C02 shared its predecessor's 8-bit instruction 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 language programmers.

The 65C02 first hit the mass market in the Apple //c portable computer.
