How to enter moves
You type four digits and then RETURN. The digits are the numbers printed around the board: the rank (row, on the left and right) 
comes first, then the file (column, along the top and bottom).

From square: the rank, then the file.
To square: the rank, then the file.

RETURN makes the move.

For example, to move your pawn on row 6, column 3 two squares forward, type 6 3 4 3, then RETURN, then P.
While typing: each digit shifts in from the right, so after four digits the panel shows From = 63 and To = 43. 
Piece shows what stands on the From square, so you can check you picked the right piece before pressing RETURN.
Typing errors: just type the four digits again. The new digits push the old ones out.

No checking: MicroChess does not check your move. Whatever you enter is moved, even an illegal move or one onto 
your own piece, so check the panel before RETURN.

P tells MicroChess to do a move.

Castling: enter the king move, RETURN, then the rook move, RETURN, then P.
Starting or switching sides: C sets up a new game with MicroChess at the top (white), and P then makes it move first. 
E exchanges sides.
