Atari 2600

If the stick is gushed forward and to the risht at the same time (tha: is, in a
northeastern direction), both the forward and rignt keypad close si~ultaneously, which
causes the
6532 to see two switch c!osures happening at once. The result is that the
object being controlled on the screen moves diagonally. With the four keypads, 8
different directions can be attained.
The pushbutton determines whether the keypad
beneath it is either open or closed. See Figure 7-2 for Joystick Schematics.
