Coleco Pac-Man mini arcade
At the height of the Pac-Man craze, video game craze, and handheld electronic craze, Coleco created mini versions of famous arcade games. They started with Pac-Man, but it wasn't long before Ms. Pac, Galaxian, Centipede, and others joined the family.
It's rather impressive how much of the flavor of the arcade originals these little versions could capture within the limits of VFD (vacuum fluorescent display) technology. The games were colorful (unlike battleship gray LCD, or red blip LED games), had a nice assortment of sound effects and music, and added simultaneous two player modes so that both you and your brother could crowd around your 9" high personal arcade cabinet.
