-The '''MOS 6502''' is an 8-bit processor that was originally developed by a team led by the engineer Chuck Peddle. It was introduced in 1975 and it is still being produced. It was produced by the following companies.
+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
-Currently it is only produced by Western Design Center (WDC)
-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.
+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.
