CatChum

CatChum is a text-only clone of Pac-Man written for the CP/M operating system and made to be operated on the early Kaypro line of luggable computers.

CatChum was made within the limitations of Kaypro's early text-only computers. As a result, the maze is made from a series of dashes and other punctuation marks. The Pac-Man character is a letter C, which goes from upper to lower case intermittently (to simulate a chomping Pac-Man). The four ghosts are capital As (which turn to lowercase ms when the CatChum Pac-Man chomps a power-pellet, capital Ms when the effect is about to end), and the "fruits" are represented by dollar signs.
