Entex Adventure Vision

Adventure Vision is a cartridge-based video game console released by Entex Industries in either August or October 1982. The monitor, game controls, and computer hardware are all contained within a single portable unit. The LED monitor can only display red pixels. Four games were released, all of which are arcade ports. Adventure Vision was Entex's second-generation system following the Entex Select-A-Game, released a year earlier in 1981. Control is through a single multi-position joystick and two sets of four buttons, one on each side of the joystick, for ease of play by both left- and right-handed players. Rather than using an LCD screen or an external television set like other systems of the time, the Adventure Vision uses a single vertical line of 40 red LEDs combined with a spinning mirror inside the casing. This allows for a screen resolution of 150 × 40 pixels. The mirror motor draws a great deal of power from the batteries, which can be avoided by using the built-in AC adapter.
