[Fairchild Channel F]
The Fairchild Channel F is a home video game console released by Fairchild Semiconductor in November 1976 across North America. 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.

[Channel F System II]
In 1979, Zircon International bought the rights to the Channel F and released the Channel F System II. The major changes were in design, with the controllers removable from the base unit instead of being wired directly into it, the controller storage was moved to the rear of the unit, and the sound was now mixed into the RF TV signal so the unit no longer needed a speaker. Only six new games were released after the debut of the second system before its death, several of which were developed at Fairchild before they sold it off.

A number of licensed versions were released in Europe, including the Luxor Video Entertainment System in Sweden, Adman Grandstand in the UK, and the Saba Videoplay, Nordmende Teleplay and ITT Tele-Match Processor, from Germany. In UVL these systems are all placed under the Fairchild Channel F platform.
