*
* 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.
