Depending on "when" you are refering to they did have a game console... the Atari 2600. which came out around the 1979 time frame. Not sure exactly when but I had one while I was still in middle school (1979/1980).
The original Space Invaders on the arcade machine was black and white and they placed a color filter on the glass that let the bottom be red and the top blue I think. At least I remember reading that somewhere.
