Your Radio Shack Mega 2050X Chess Computer is one of the most advanced and
versatile chess computers available.  Ideal for everyone from the
professional and tournament chess expert to the beginner or casual player,
the computer can be a relentless chess opponent, yet is easy to set up and
play.

The computer's advanced options let you simulate the sights, sounds, and
intensity of championship and tournament play.  You can let the computer
act as a referee while playing against another person, turn the computer's
sound on or off, and display and hear a ticking game clock during play.
The computer also displays information that can help you improve your chess
skills either continuously during a game or by pressing a few buttons at
any time.

The computer's features include:

             Special Sensory
             Playing Surface - the computer senses a move when you press a
                               piece against a square.

                 LCD Display - shows current move, piece position and
                               verification, level, position set up,
                               search depth, principal variation, position
                               search, rotating display, and elapsed game
                               time information.

     Rotating Display Option - lets you set the computer to display move
                               strategy, search depth, time per move, move
                               totals, evaluation rating, and move
                               possibilities per second continuously
                               during a game.

       Built-In Chess Clocks - let you set the computer to display the
                               elapsed time since the computer or an
                               opponent last moved, and the remaining time
                               before the computer or an opponent must
                               move. The computer can also display count-up
                               and countdown game timers.

  Rank and File Board Lights - let you easily see where a piece came from
                               and where it should go during a move.

      Sixty-Four Play Levels - let you choose from 64 game types and levels
                               of difficulty, including tournament, sudden
                               death, mate search, regular play, training,
                               and beginner levels.

                   Take Back - lets you take back and replay moves.

            Rule Enforcement - prevents illegal moves.

                        Save - lets you turn off the computer without
                               interrupting the game in progress so you
                               can continue playing later.

                        Move - lets you force the computer's move, change
                               sides with the computer, or learn by
                               watching the computer play against itself.

             Move Suggestion - lets you use the computer to suggest moves,
                               to teach you the best response to an
                               opponent's move.

              Problem Set Up - lets you set up special chess problems, so
                               you can practice solving problems published
                               in newspapers, chess literature, or history
                               books.

         Opening Book Memory - contains most major opening strategies so
                               the computer can respond more rapidly during
                               a game's opening moves.  You can set the
                               computer to use none, some, or all of these
                               moves during play, or select tournament
                               opening books for the most challenging play.

       Position Verification - lets you check the current position of the
                               pieces.

                  Evaluation - shows the computer's assessment of which
                               player has the advantage and how much of an
                               advantage that player has.

            Power Off Option - lets you save battery power by setting the
                               computer to turn itself off if you do not
                               press a key or board square for about 15
                               minutes.

           Two Power options - let you power the computer from batteries
                               or from AC power with an optional AC adapter
