The DOS version will run in DosBox or on actual hardware, and has EGA graphics (unless you run the 'terminal' version). The Linux version is console only and very bare-bones, although it can look a lot deeper if run on a modern machine! I do intend to make it compatible with the UCI protocol at some point. Note all versions take one optional command-line parameter - number of seconds thinking time per move.

Moves are issued in long algebraic form - i.e. 'e2e4'. Other commands are:

Command	Effect
quit	Quits the game
restart	Restarts the game
undo	Reverts the previous move (computer or human)
play	Forces the computer to play a move. Therefore, if you want to play as black, type 'play' on white's first move. Keep typing 'play' to watch the computer play itself.
set	Toggles between the two piece tilesets
eval	Displays the board evaluation for white and black
setup	Allows you to setup the board. Cursor keys move the active square. 'c' clears the board, and to place pieces use their corresponding key ('n' for black knight, 'Shift+N' for white knight, etc). 'Esc' to leave setup - only allowed if each side has one king.
flip	Flips the board so black is at the bottom and white at the top (and vice versa).
