LED Games

After electro-mechanical games, and before "true"took videogames  over the arcade scene, there were some arcades and pubs with LED coin-op games.
These games were made of a panel of monochromatic LED lights that turned on and off, representing all the elements of the game. For example, if the game was a version of Space Invaders, the base, the aliens and the shots were all made of LEDs.
