 *
 *  Input ports
 *
 *
 *  The Astrocade has ports for four hand controllers.  Each controller has a
 *  knob on top that can be simultaneously pushed as an eight-way joystick and
 *  twisted as a paddle, in addition to a trigger button.  The knob can twist
 *  through about 270 degrees, registering 256 unique positions.  It does not
 *  autocenter.  When selecting options on the menu, twisting the knob to the
 *  right gives lower numbers, and twisting to the left gives larger numbers.
 *  Paddle games like Clowns have more intuitive behavior -- twisting to the
 *  right moves the character right.
 *
 *  There is a 24-key keypad on the system itself (6 rows, 4 columns).  It is
 *  labeled for the built-in calculator, but overlays were released for other
 *  programs, the most popular being the BASIC cartridges, which allowed a
 *  large number of inputs by making the bottom row shift buttons.  The labels
 *  below first list the calculator key, then the BASIC keys in the order of no
 *  shift, GREEN shift, RED shift, BLUE shift, WORDS shift.
