Adventure Vision is a totally new and unique concept in personal graphics display. It utilizes computer age solid state electronics and through its special viewing screen systems, enables us to place over 6,000 separate and distinct light locations for a graphic display that is virtually unequaled.
One year after the release of their unsuccessful Select-A-Game Machine, a bulky handheld with interchangeable games, Entex Electronics released a stand-alone tabletop console called the Adventure Vision. In lieu of using the vacuum fluorescents found in their handheld games, Entex devised an odd and innovative display technology that used a two-sided, spinning mirror to reflect a column of red LEDs. Housed in a mini-cabinet with joystick and mirrored 4-button controls, the Adventure Vision tried to replicate the arcade experience at home. Though covered extensively in the popular games and electronics press, reviewers noted the display's noticeable flicker and poor performance in direct light. Entex would release only four games for the system, ultimately abandoning the cartridge concept in favor of their more successful dedicated handheld electronic toys.
|RAM||64 bytes (internal) | 4x 256-byte banks (external)|
|VRAM||750 bytes (from external RAM)|
|Resolution||150x40 (see Graphics below)|
|Palette||monochrome (reflected red LED)|
|Graphics||The Adventure Vision's built-in video display reflects a vertical column of 40 red LEDs off a belt-driven mirror that spins at approximately 450 RPM, or 7.5 rotations per second. The mirror is two-sided, which means it can produce two video "frames" per rotation, giving the system an effective display refresh rate of 15 FPS.|
|Sound||COP411L single-chip microcontroller (16 tones, 13 SFX)|
|Input||1x center 4-position joystick | 2x cross configuration of 4 action buttons (though each set are wired together, so input is effectively mirrored on either side)|
