The Fairchild Channel F, F for Fun[2], is a home video game console released by Fairchild Semiconductor in November 1976 across North America[3] at the retail price of $169.95. It was also released in Japan in October the following year. It has the distinction of being the first programmable ROM cartridge–based video game console, and the first console to use a microprocessor. It was originally named Video Entertainment System, or VES, but when Atari released its VCS the next year, Fairchild changed the name for its machine, although they continued to use the old name alongside it. By 1977, the Fairchild Channel F had sold 250,000 units, trailing behind sales of the VCS.[1]
The Channel F System was my first video game system. Fun times with very little bits and colors. Vroom vroom.
