The Atari computer reads the horizontal and vertical positions of a light pen
or a light gun in the same way.  Consequently, while software programs are
designed for one or the other, these two types of controllers may often
substitute for each other.

Note that on the 400, the light gun / light pen will only work in joystick
port 4.  This renders much light gun and light pen software unusable on the
400.
