Electro-Dart (Electronic Sensing Products, Inc., 1972)

The Electro-Dart wall game was one of the earliest electronic coin-operated wall games.   There were no microprocessors employed in this game, since it predated the Intel and Zilog CPUs by about 3 years.  All logic functions were performed by TTL logic ICs and other discrete electronic components.

An interesting variation of the wall game concept was introduced with this game - two separate display panels.  The Target Panel and the Player Panel were joined by a multi-conductor cable.  All electronic components were contained in the Target Panel.  The Player Panel only contained lamps, sockets, and wiring which were controlled by the circuit boards in the Target Panel.  There was no sound component to the game.
