This cartridge is interesting for two reasons. First, because it plays a very similar version of the oldest video game ever made: Ralph Baer's Chase Game. The game consists of two squares (players) chasing each other. In Baer's version, the square had the same size, but one would disappear uppon colision with the other. Here, the squares have different sizes to avoid confusions while playing, and a beep is produced when one player thouches the other.

The circuit board of this cartridge is the simplest of all Video 2000 cartridges: it contains just a few resistors to enable the two players and set their sizes, and one 4011 CMOS chip which acts as a collision detector (Player 1 AND Player 2 = Collision) and a capacitor to filter parasites in the 4011 power supply.


Attacke game. Only two squares.
