Hunt the Wumpus is a classic computer game, written in BASIC by Gregory Yob in 1972. This port is for the PDP-8, a machine that actually predates the game by a number of years. I've tried to keep this game as close as possible to the original (although I have corrected a few of Gregory's typos).
This game is written in PDP-8 assembley language and is suitable for the PALBART assembler. If you don't have a PDP-8 to hand, you could use the SIMH simulator.
