http://www.annablack.com/colossal-adventure Came across this beautiful 1983 copy of the Level 9 text adventure game for the BBC yesterday. It appears to be complete including the “hint envelope” 
“Colossal Adventure is a full scale version of the original, classic, mainframe game “Adventure”: with added 70 locations. All crammed into your micro. This massive, pure text adventure has over 200 locations and a wealth of puzzles which may take months to solve.”
