Yes.  The 2600 trackball has a small switch on it for selecting either
joystick mode or trackball mode.  In joystick mode, it sends signals
as if it were a joystick.  Roll the ball left, and it sends a joystick
left.  Roll the ball up & right and it sends both up and right
signals.  In trackball mode, (I believe) it's supposed to be more a
matter of sending a vector, where both speed and direction are
important.  As far as I know, there are no 2600 games that can use the
trackball in trackball mode.  Only in joystick mode.
