The Ultravision Video Arcade System (VAS) was an unreleased gaming console announced in 1983. The slogan provided by the company, "It's a game! A computer! A color TV!", was intended to demonstrate how the game console was going to be a computer that was accessible and non-threatening to consumers.
Design
The system was composed of a standard 10" color television integrated with the game console, and controlled by two 16-direction joysticks with top-mounted buttons. It could run off either AC or DC power, making it portable by allowing it to run off a car battery.
In addition to supporting its own line of game cartridges, the console was intended to have plugin modules that would have supported the ColecoVision and Atari 2600 game libraries.
