Analog Joystick Interface [need better description]
The reading of a Joystick is nearly the same as Vectrex. A value is placed in the shared Y axis
DAC, a reading from a comparator is taken and returned as a single Hi/Lo bit, it’s up to the
software to do whatever type of binary search it takes to determine the joysticks value. The joystick
shares the DAC.
