Although it might take you months to fully explore all the features your
computer offers, you can begin using your computer within minutes.

Begin by following the steps in "Playing Against the Computer".  Then, read
the rest of "Basic Operation" for more detailed information.

After you know how to start a game, enter moves, and read basic displays,
refer to "Additional Features" for information about the computer's more
advanced features.

NOTES:  When you first turn on the computer, the play level is A3.  We
        recommend you play at this level until you are familiar with the
        basic steps for using the computer.  If you find this level too
        difficult or too easy, you can later change the level as described
        in "Play Levels".

        Normally, you play the white pieces and the computer plays the
        black pieces.  We recommend you play this way until you are
        familiar with the basic steps for using the computer.  You can
        later change sides as described in "Changing Sides".

PLAYING AGAINST THE COMPUTER

computer.  To remove the compartment cover, press the latches in the

6.  Move the piece to its new position and press it down.  The BLACK
    indicator flashes while the computer plans its move.

NOTE:  During the opening moves of a game, the computer operates from its
       opening book memory, and indicates its moves almost immediately. 
       The computer also plans during your turn, so it might immediately
       indicate a move even during the later moves of a game.

7.  When the computer decides its move, row/column indicators light to show
    you which piece the computer wants to move.  In addition, the display
    chessboard alternately flashes the piece's current and new positions.

           on the display chessboard.

    The display message also indicates the current position and new
    position coordinates.

    Press down the indicated piece on its current square.

    piece, and the display chessboard continues to alternately flash the
    piece's current and new positions.  Move the piece to the indicated
    square and press it down.
