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.


Entex released four Adventure Vision games, all of them ported from arcades:

Technical specifications[edit]

  • CPU: Intel 8048 @ 733 kHz
  • Sound: National Semiconductor COP411L @ 52.6 kHz
  • RAM: 64 bytes (internal to 8048), 1K (on main PCB)
  • ROM: 1K (internal to 8048), 512 bytes (internal to COP411L), 4K (cartridge)

A similar display technique combining red LEDs with a moving mirror was used by Nintendo in the 1995 Virtual Boy.

On March 31, 2013 at the Revision demoparty, the first-ever homebrew/demo ROM for the system was demonstrated[2] by MEGA - Museum of Electronic Games & Art. MEGA also released[3] the source code for the demo as well as all development tools.

The system is supported by the MESS emulator and AdViEmulator.[4]
