VERIFYING PIECE POSITIONS

If you want to verify the location of any piece on the chess board, you
can use the piece symbol keys any time to find the position of all pieces.
Each time you press a piece symbol key, the computer displays the piece's
color and location, and the rank/file board lights indicate the piece's
location.

For example, if the white queen is on square D1 and you want to verify its
location, press the queen piece symbol key once.  The computer displays
[] (queen symbol) d1.  Or, if the black queen is on square F6 and you want
to verify its location, press the queen piece symbol key twice.  The
computer displays [] (queen symbol) F6.

To locate all pieces of the same type, repeatedly press the piece symbol
key for the type.  If there is more than one of the same color piece of
that type on the board, the display and the rank/file board lights show
the location of each like piece each time you press the piece symbol key.
If you continue to press the piece symbol key, the display and the rank/
file board lights show you the location of each of the other color's
pieces of the same type.

Note:  If you press a piece symbol key more times than the total number of
       pieces of that type on the chess board, the display shows the piece
       symbol only.

Press CLEAR to return to normal play.

TAKING BACK MOVES

This function lets you take back any move made by you or the computer
after the move has been completed.  The computer even reminds you to
return a previously captured piece to the board or a castled rook to its
original square.

Notes:  If you are not sure about the position of a previously captured
        piece or castled rook, see "Verifying Piece Positions", above.

        If you change your mind about a move before pressing a piece down
        on its TO square, follow the procedures in "Correcting Accidental
        Wrong Moves" in Faxback Doc. # 47015.

        To take back your own move, you must take back the computer's
        counter-move first.

1.  Press TAKE BACK.  The rank/file board lights show the TO square of the
    last move, and the display shows [] or [], the piece symbol for the
    last-moved piece, the FROM square, and the TO square of the last move.

2.  Press the piece on the indicated TO square.  The rank/file board
    lights change to show the FROM square of the last move.

3.  Move the piece from the TO square to the FROM square.

4.  Press the piece on the indicated FROM square.

    Note:  The game timer shows the total amount of time the computer has
           taken to move during the current game.

5.  Repeat Steps 1 through 4 to take back additional moves.  You can take
    back up to 30 ply of moves (a ply is one of your moves or one of the
    computer's moves).

PROBLEM SETUP

You can use the setup mode:

  To erase, re-enter, or relocate pieces any time before or during a game.

  To set up problems or puzzles for the computer to solve.

Note:  If you have already started a game, you must press POSITION during
       your turn to enter the setup mode.  If you have not yet started a
       game, you can press POSITION any time.

Before using this mode to create your own positions, familiarize yourself
with this procedure by setting up the board positions described in the
following examples.

Full Board Setup

In a full board problem setup, the computer records the positions you
enter into memory and assumes all other pieces remain in their initial
positions.  You only need to go through these steps for pieces that you
want to remove or move from their initial positions.

Follow these steps to set up a game with most of the chess pieces in their
original positions.

1.  Set up all of the pieces on the board.

2.  Press NEW GAME.

3.  Press POSITION.  The computer displays -POS-.

4.  Press the piece symbol key for the piece you want to move or remove
    and []/< or []/> to change the color, if necessary.  The computer
    displays [] or [] and the piece symbol for the piece you want to move
    or remove.

5.  Press the piece you want to move or remove on its FROM square.  The
    computer displays [] or [] and the piece symbol, -, and the square the
    piece is on.  The rank/file board lights also show the piece's FROM
    square.

6.  If you want to move the piece, move the piece to the desired square,
    then press it on the square.  The computer displays [] or [] and the
    piece symbol, +, and the TO square the piece is on.  The rank/file
    board lights also show the piece's TO square.

    If you want to remove the piece, just remove the piece from the board.
    The display does not change.

7.  Repeat Steps 5 and 6 for any other pieces you want to move or remove.

8.  When you finish setting up the pieces, press []/> until the computer
    displays [] or [] for the color that will start, then press CLEAR.
    Or, simply press CLEAR, then choose the level you want and begin the
    game.

Note:  If the computer beeps an error tone, one or more pieces were moved,
       removed, or entered illegally.  To correct the set up, see
       "Correcting Illegal Setups" below.
