Cops | Classic retro game for the Commodore PET Computer (1979)

COPS is based on an asymmetrical cops-and-robbers game known as the hamstrung squad car discussed in Martin Gardner's Mathematical Games column in Scientific American (February 1967, p. 116). I'd link to the article, but access to back issues is limited to subscribers (about $30 a year at the time of writing). If you search for hamstrung squad car, you can learn more about the mathematical ideas that underly this game.

This PET implementation is functional, but the presentation is bland. The PET does not participate in the game; you need two players for this one. There's enough leftover RAM that Fisher could have programmed the computer to play as the robbers with some rudimentary evasion logic.
