Adventure Vision was considered state-of-the-art in 1983 as it was
the only tabletop cartrige-based game system (unless you consider the
Vectrex as such as well). Entex's machine required no TV hook-up since
the screen was built-in, with 6000 light locations to create images with
more than 20 times the resolution of any table-top game on the market
at the time. It used four "D" batteries (not included) and came with
a Defender game cartridge. Adventure Vision also featured a full fidelity
speaker that produced unrivaled sound effects.
The game library was tiny, as Entex called it quits shortly after
introducing the Adventure Vision. Defender, Turtles, Super Cobra and
Space Force. Today, the machine is extremely rare and is considered
among the highlights in a collection among those who own one.
