Mystery Maze Version 4.2 
Super Software
1981
300 Baud Version:

As Paul Thacker notes on the Bally Alley discussion group on April 5, 2011:

"It would be good to mention on Bally Alley when we had to modify programs to 
get them to work. [...] in Mystery Maze, the printed source code and unofficial 
tape had line 100 ending with GOTO 130, but since there was no line 130, we 
determined that GOTO 120 made the most sense."
