that is to move.
7 .3 Automatic take-back option
Let's assume that you have just made a very bad
move and realized your mistake immediately after
executing it on the board. Naturally, you now teel
the desire to retract that move.
After the computer has announced its answering
move and you have executed it on the board.
there are two alternatives:
1) You can enter Memory Mode as described in
section 7.2 and take back the last two half moves
of the game.
2) You can take back first the computer's last
move and then your own move directly on the
chessboard,
without entering Memory Mode. by
simply carrying them out in reverse. MEPHISTO"s
a�tomatic take-back facility will recognize your
w1sh to retract these moves' and pass it on to the
program.
However. when taking back a longer sequence of
moves, your memory may fail you. so it is better to
use the method described in section 7.2 in order to
avoid any mistakes.
On the other hand, when taking back only a tew
7.2 Taking back move
MEPHISTO's interna! memory allows you to play
the current game backwards, either in its entirety or
far a few moves only. Press the MEM key to enter
Memory Mode while it is your tum to move. In the
display window you will see the message "memo".
By repeatedly pressing the input key labelled <-9,
you can now take back as many moves as you
like. Every tirne you press the key, there will be a
tone signal, the corresponding LEDs will start
flashing and the move to be taken back will be
shown in the display window with three dots
between the characters.
Execute each backward move by replacing the
respective piece on t� square it originally came
from. lf after doing so you observe that one of the
LEDs is still flashing, this means that the move you
have just taken back was a capture and that you
need to restore the captured piece to its original
square.

Moves that have been taken back in the fashion
described above may be played forward again by
repeatedly pressing the key labelled ->0. Again,
the moves will be shown both in the display
window and on the board by means of the
corresponding square LEDs, but there will be no
tone signal.
As soon as you have reached a position from
which you would like to continue the game, leave
moves, the automatic take-back option is to be
preferred, since it allows you to retract moves
without pressing any keys.

MEPHISTO's interna! memory allows you to go
back to the beginning either during or after a
game.
