The Vectrex's base technical specifications were impressive. It used the speedier and more advanced Motorola 68A09 (6809) instead of the cheap MOS Technology 6502 8-bit microprocessor found in early Apple, Atari and Commodore computers. Likewise, its sound generator, a General Instrument AY-3-8910, supported a competitive three simultaneous channels of sound with a dynamic range of effects. The chip had been used in Mattel's earlier Intellivision (1980) and would show up in the Atari ST (1985) and other computer systems.
The Vectrex is a masterpiece of design. The control panel, which features a small self-centering analog metal joystick and four numbered action buttons, could be placed in a storage area at the bottom front of the console. The coiled cord would be wrapped once around the joystick, with the remaining length laid on top of the action buttons. The control panel could then be slid into the tabs at the bottom of the console and snapped up into place, creating a sleek forward-facing profile.
The Vectrex shipped in a large, rectangular silver-toned box with Styrofoam inserts. Inside the box was a single control panel, owner's manual, owner's club registration card, and the color screen overlay and instructions for the built-in Mine Storm game.
One obvious liability of the Vectrex is its black and white display. Even in the early 1980s, monochrome was seen as a serious limitation in a game system, no matter how innovative its display method might be. This potential deal-breaker was addressed with heavy gauge, flexible plastic overlays produced for each game. These overlays fit snugly into plastic grooves on the top and bottom in front of the monitor, and featured high quality color printing.
The overlays not only improved the games' aesthetics, but also provided simple instructions. The translucent, semi-transparent overlays also reduced the flicker inherent in vector displays. Since the overlays weren't designed until after a game was considered finished, they often frustrated programmers, since further code changes had to accommodate the position of an overlay's design elements. Nevertheless, the colorful overlays generally helped to enhance each game's presentation and remain one of the Vectrex's most iconic elements.
