To check the position of the pawns, press the "PAWN" ( i ) key. The
LED at the other end of the third row lights up, indicating that the row
closest to white, where there is already a pawn. At the same time it tells you
which square of this row the pawn must occupy, the diode lights up at the
foot of the "d" and "g" column (the fourth and seventh column from the left).
Now press the "PAWN" key ( .!. ) again. The next row that has a pawn on it
is the fifth row. Thus the diode of this row lights up, at the same time as that
at the foot of column "e". At this same moment, the diode in the "f" column
starts to flash. This tells you that the pawn on square 15 is a black piece.
Press the "PAWN" key ( ) a third time, and the LED of the
sixth row will light up, while the LED in column "e" is flashing. If you press
a fourth time, no square will be indicated, this tells you that there are no
pawns on the chessboard, only those which have been signaled to you before
(by pressing the "PA" key a fifth time ^WN" ( ) will give you the same
result as the
first - the computer starts demonstrating the position of the pawn, again).
Similarly, you can control the positions of kings and rooks; a white piece
indicated by the "ROW" and the "COLUMN" with the diodes lit
continuously, while in the case of the black pieces the "COLUMN" begins to
flash. Of course, if you press the "queen", "bishop" or "knight" key, none of
the squares will be indicated since there are no such pieces on the
chessboard.
When you have ^al your vocation, just keep playing.
The LEDs stop indicating the position of the piece when you press the
square or the key.
