			The keyboard can be scanned through PIA-1 by pulling two values from addresses $FF00 and $FF02. [[Color Basic]] ROM, when running a prompt, converts these to ASCII values to be printed to the screen at cursor position. The first address ($FF00) represents the keyboard rows as well as the joystick button, and the second address ($FF02) the keyboard columns. These two value correspond to ASCII values according to the following table:
