Atari Video Computer System

The Atari 2600 4 Switch, technically called the Atari Video Computer System, is a later model that replaced the 6 switch original that moves the difficulty switches that were on the front side of the unit to the back, leaving the front side with only four main switches (Power, TV Type, Game Select, and Game Reset). The channel selector switch is also located on the back of the unit as well for easier access.
