Are we talking Zork I here? I at first thought of the old MIT version which (AFAIK) predates the commercial Zork-[1,2,3] and was written in (or at least distributed as) Fortran. I'm told it included most of what was in all 3 commercial Zorks, but have no direct personal knowledge of that.
(I recall having hacked the Fortran source in to C, using F2C, back when I ran Coherent at home, pre-linux, and with only a bit of butchering of the resulting C got a working game. several years prior to that, I also had a version for PDP-11, at work.)
which Zork?
