I believe running a PDP-10 (real or simulated) and matching the original programming environment would produce the most accurate representation for the original adventure. I have a simulated PDP-10 running (see my URL above) with session logs on how to set this up. However, the matching old version of the PDP-10 operating system and Fortran compiler Crowther used are unknown and may be lost. A PDP-10 with later OS and Fortran still compiles and runs Crowther's and Crowther's/Wood's code as is, and all print terminal input/output can be logged. Below is Crowther's adventure (see build-adv0.txt) as it would have been printed on a PDP-10's hard copy terminal:
.RUN ADV31

WELCOME TO ADVENTURE!!  WOULD YOU LIKE INSTRUCTIONS?  

YES
SOMEWHERE NEARBY IS COLOSSAL CAVE, WHERE OTHERS HAVE FOUND 
FORTUNES IN TREASURE AND GOLD, THOUGH IT IS RUMORED   
THAT SOME WHO ENTER ARE NEVER SEEN AGAIN. MAGIC IS SAID    
TO WORK IN THE CAVE.  I WILL BE YOUR EYES AND HANDS. DIRECT
ME WITH COMMANDS OF 1 OR 2 WORDS. 
(ERRORS, SUGGESTIONS, COMPLAINTS TO CROWTHER)    
(IF STUCK TYPE HELP FOR SOME HINTS)    

YOU ARE STANDING AT THE END OF A ROAD BEFORE A SMALL BRICK 
BUILDING . AROUND YOU IS A FOREST. A SMALL  
STREAM FLOWS OUT OF THE BUILDING AND DOWN A GULLY.    

GO IN
YOU ARE INSIDE A BUILDING, A WELL HOUSE FOR A LARGE SPRING.

The font, and maybe the command to start the adventure program, may differ with the true original hard copy. I think the print out may be the more accurate representation. Since, that was how Crowther wrote and played the game?
