Written by Martin P. Briant, COLOSSUS CHESS 2.0 was published in 1984. Simple graphics, but the game itself and the options are all well thought out.
The PC direction keys can be used to play COLOSSUS CHESS 2.0. M = Level Mode, there are 6 Modes. Mode 1 = Time per move mode. Mode 2 = Tournament Mode. Holding down the TAB key and pressing the letter O, orientates the chess board. TAB plus letter N = New Game. Pressing SPACE BAR at any time takes you to the Analysis Screen.
You can find OPTIONS by pressing all the keys and making a note of the functions. Most of the functions are hidden therefore also try to press all the keys while holding down the TAB (= RESTORE key on a Commodore 64/128) key and also the SHIFT key.
