An IBM PC/AT model 5170 sits inside an abandoned room, inside an abandoned home, located in an abandoned town, totally surrounded by a large but incredibly secretive military installation. This IBM has been set to the task of playing a game of unknown origin seemingly autonomously for fifty years. This is Location Nil, and there is no place on earth quite like it. Here the computer has remained, carefully guarded. At first, it was protected merely due to scientific curiosity - later, out of what can only be described as existential paranoia.
