The third button is available to those who build their own paddles (me!),
as well as TWO other paddles (total of four dimensions, or two joysticks).
The only sad thing is that no software company (that I know of, ed.) ever wrote
anything to take advantage of any of these "non-standard" extras. I've often
wondered what a dual joystick version of video games would be like!
