This is a remake for the Commodore PET of Malcolm Evans' classic ZX81 / TS1000 game 3D Monster Maze.

Explore a randomly created 3D maze trying to locate the exit and avoid the other inhabitant of the maze, a Tyrannosaurus Rex who is out to get you.

This will run on a PET / CBM 4032, Mini PET or Mini PET 40/80. Older PETs upgraded to 32K and BASIC 4 should also work ( although not the 2001 with the built in datasette). Mini PET 40/80 owner can also use 80 column mode for a special cheat / trainer mode which provides a Pterodactyl's eye view of the maze to help you find the exit and learn how Rex's simple brain works.

The file provided is a PRG file that can be loaded on a real PET or an emulator. 

Physical copies on cassette are also available from :
