We need some way of telling the human player what move has been made, and accepting a move for the human player. We also need to warn about checks, and detect and announce the end of the game.

There are many ways of doing this, a graphical display, a simple text display of the board, an even simpler display of the moves, or even a robot

The program has three alternative modules which can be linked in to provide:

DOS based display: A simple DOS console for the game. Extremely useful during testing

RCX only UI: The moves are displayed in A1-H8 notation on the RCX's display, and moves are entered by cycling through the available moves with the RCX's buttons

Robot Version: Moves are detected and made to phisical pieces using a robot - for more information see the robot section
