It 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. | It was second-sourced by other companies such as California Micro Devices (GTE Microcircuits), Rockwell, and Synertek. | ||
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. | |||
