}} introduced in 1975 that was originally developed by a team led by the engineer Chuck Peddle at MOS Technology (later purchased by Commodore). | |||
It was second-sourced by other companies such as California Micro Devices (GTE Microcircuits), Rockwell, and Synertek. There are several less popular variants, including the 28-pin 6503, [[Rockwell R6504|6504]], 6505, 6506, and 6507 with fewer address pins (4K or 8K address space) and various control signal options. | |||
Western Design Center (WDC) first developed a CMOS version, which is still in production as of 2019. In addition, several implementations (commercial as well as free) are available to synthesize the core into FPGA designs. | |||
The 6502 was a popular choice of processor because of its low price and high capabilities. It was used in multiple early computers such as the Commodore 64, Commodore VIC-20, Apple II, BBC micro, and many others. | |||
