Keyboard Port Based Inputs
« on: March 30, 2008, 10:59:07 am »
New guy here.  On page 207 of the book, it says "the Project Arcade control panel design uses 32 keyboard port based inputs.  That includes all controls except the trackball, spinner, and three mouse buttons."  However, back on page 154, the design shows a spinner, trackball, 2 8-way joysticks, 1 4-way joysticks, and 27 buttons (7 per player, 3 mouse buttons, and 10 admin).  Based on that I count 27 keyboard port based inputs, not 32.

What am I missing here??? :dunno

Each joystick uses 4 inputs (up,down,left,right), except the 4-way is mapped to the same inputs as the player 1 8-way, so it doesn't take any extra inputs (in other words, up on the 4-way will press the same key as up on player one's 8-way).  That means 8 inputs total for the 2 joysticks, 7 buttons per player, and 10 admin = 32 keyboard inputs.
