Problem mode
Your computer has a special problem mode (Level H) in which
it will solve chess problems up to mate in 10 moves. Press
I P L A Y I to start computing for checkmate. A corresponding
lamp will light to indicate the depth of computing. In this
mode the computer will only make a move if it can see a
forced mate in 10 moves or less. Complicated moves may
take hours/weeks. Press P L A Y |to stop the search any time you
like.
If the computer finds a forced checkmate it will play the first
move — the "key m o v e " — which will lead to mate. You may
try to defend the position for the opposite side (the side being
checkmated) by entering moves as usual. The computer will
continue playing the checkmating side until the game is over.
If the computer does not find a forced mate for the side it is
playing, it will give a double beep and make no move.

Display Moves
This is a unique feature that allows you t o observe the
"thought process" of the computer. To activate this mode
press | DISPLAY M O V E | . The computer will now show you
the moves it is considering while it computes a move. It will do
this by turning on the FROM square for three seconds and
then the TO square for one second. You can watch how it
changes its mind as it computes deeper. Pressing
| DISPLAY M O V E [ again switches off this feature.
If you wish to interrupt the computer while it is computing a
move simply press | P L A Y
. This does not operate in the
problem mode.
