This was a fun multi-year project for me. I had to reverse engineer everything from the Fortran executive and the very incomplete documentation for the game.
I learned FORTRAN in at a summer job between jr and sr years of high school from the source code of some version in 1978 on a MODCOMP mini computer with IBM terminals where I saw zeroes with dots in the middle for the first time.
