What is a wall game?

Before video games took over the bars and arcades, Gremlin Industries of San Diego built wall games: big, flat, wall-mounted cabinets with a printed backglass and rows of lamps behind it. No screen. Everything you see is a painted picture lit from behind by individual bulbs, switched on and off by digital logic.

In TRAPSHOOT two teams take turns at a hand-held radio transmitter with a single button. Press it once and a traphouse launches a clay bird across the sky - a chase of lamps across a dotted arc. Press it again and your shooter fires. Time it right and the bird bursts, the HIT SCORE coins count up, and the EXPERT trophy might light with a roar from the crowd.

Behind the glass sits a single printed circuit board two and a half by five feet, and a game costs one quarter.

An EXPERT hit in the simulation: the burst, HIT SCORE 1 through 4 and the big trophy, exactly as the real lamps do it.
