square. Obviously, this feature lets you
strengthen your side or the computerʼs,
resurrect lost pieces, or even more your
King out of an imminent checkmate
threat.
You can do this in checkers and chess.
Clearing the board to set up a position
To set up a special problem, it is
normally easier to start from an empty
board. So fi rst, clear the board by
pressing NEW GAME, SER UP and
OPTION. The display will read "NO
NE."
Setting up a position in chess
Place the desired pieces on the board by
pressing the PIECE SYMBOL key and
the square to be occupied--press once for
White, twice for Black.
After setting up the pieces, tell the
computer whose move it is by pressing
the BLACK/WHITE key. The word
"SIDE" will appear on the display. Press
the key repeatedly until the black or
white indicator box in your display is the
color you wish to have move fi rst.
Keep this procedure and sequence
in mind, and the SET UP pro-
cedure will be easy to use: After
you press SET UP and the piece-
symbol key you select by pushing
the square the piece stands on, you
can change its color or remove
it. If the piece is White, one push
changes it to Black, a second push
removes it. If the piece is Black,
one push removes it, a second push
reinstates it as White.
