There is a simple way to use the Atari Trackball with marble madness or
any other game that can use a joystick.

There is a switch on the bottom that select whether the Trakball is in 
Trakball mode or Joystick mode. Just switch it to "joystick". On Marble
Madness, just select joystick on port 2, plug in the trakball to port
2 and go for it.

If you want to use the trackball as a mouse, you have to do some rewiring
as the pinouts are not the same as the mouse's. There was an article in
an old issure of Amazing Computing on how to do this. I don't know which
issue it was now, but it's been about 2 years ago.
