This is a very rare dedicated pong console which doesnt use any dedicated chip (like AY-3-8500-1), it only has discrete components (TTLs).
Was released in 1976 by Video Marketing Corp. and only plays two games: Tennis and Handball.

It features scoring on screen thanks to a MM5841 chip (those chips were usually used for displaying time on a TV but can also be used as a scoring display) and you can also play versus a robot (left or right player) or you can also select the two robots to plays against themselves.

There is a detailed review of this pong console which is published in the magazine Elementary Electronics - January-February 1977 edition.
