You might have seen this posting on Slashdot (or in my RSS headlines) about the original FORTRAN Adventure source code being found in an archive.
Originally written by Will Crowther, Adventure was the first text adventure game. Most people are familiar with a subsequent version that was expanded and edited by Don Woods.
Long thought lost, Crowther's original source code has been located in a backup of Don Woods' Standford student account from 1977.
Matthew T. Russotto has already translated the PDP FORTRAN to g77 (GNU FORTRAN 77) - which means that most modern gcc installations should be able to compile it.
He has a link here: http://www.russotto.net/~russotto/ADVENT/
I've gone ahead and compiled it on my PlayStation 2 Linux box (mips binary) - and on my laptop under Cygwin (x86 binary). I've never used GNU FORTRAN before - very interesting. I might have to peep the source code a bit - last time I used FORTRAN was in 1983 in college.
