CBS Games was a third party producer of Atari 2600 games. CBS began making 2600 games in 1982 and started by licensing high profile arcade games from Bally. They also invented RAM+, an extra chip for Atari 2600 games that increased the RAM of the 2600. This chip was used in Mountain King, and received rave reviews from fans and critics. CBS fell victim to the videogame crash and ceased publication in 1984.
