=== Paddles

One paddle is controlled by moving the mouse left and right; the other
paddle is controlled by moving the mouse up and down. The paddle buttons
are emulated by the mouse buttons (left and right click).

to create two real-time clock references. This is emulated by the Epple ][. Paddle timers 2 and 3
are 100-microsecond and 1-millisecond references, respectively.
