Attacke (cassette 3) 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 Ralph Baer's version,
both players had the same size, and one would disappear uppon colision with the
other. Here, the players have different sizes to avoid confusion while playing,
and a beep is produced when one thouches the other.
The circuit board of this cassette is the simplest of all:
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). A capacitor filters parasites from the power supply.
Attacke game. Only two squares.
