I played my first game of OXO on Martin Campbell-Kelly's EDSAC Simulator. I figured out how to load the OXO tape, use a rotatry telephone dial to input numbers, and switch to the correct 'long tank' to display the visuals of the first known visual computer game on the cathode ray tube. I figured out how to play the game against the AI, and of course, the game was a draw. As it turns out, the only winning move is not to play.
