	* TRUE IN THEORY *

Anyway, the 1350 contains a clever 4-bit process that translates
the quatrature signals into joystick pulses.  This provides good
software transparency.

The new mouse, the 1351, contains an even more clever gate array
that provides the same joystick emulator *AND* analog joystick
game paddle emulation.   This works much better, as long as the
software is prepared to play along...
