In this different from the one credited to be by David Matusek and Paul
Reynolds? I have FORTRAN source for what I think is the Trek game that
we ran on TOPS-20 when I was in college in the mid-80s. I have been
trying off and on (mostly off recently) to get it working under SIMH,
but haven't touched it in so long that I can't remember where I was at
on it.
It was on a 9-track tape of stuff that I collected when I graduated and
LCM was kind enough to read for me a few years ago.

Dan,
The link to your Source Forge page you posted does not work for me. I
found TREK7 it at https://sourceforge.net/projects/trek7/.
I tried to find the sources you started with. I found a ZIP file
called trk7fsrc.zip
<https://sourceforge.net/projects/trek7/files/trek7/status/trk7fsrc.zip/download>.
When I compiled the first file, TREKA.FOR, I can see typos and lines
extending past column 72. This could not be the original source code
that worked at one time. Was this scanned? Has this been altered
from a known working version, other than the scanning errors? Like,
the lines that extend past column 72? The code clearly expects column
72 to wrap to column 7 of a continuation line, which is how Fortran
fixed-format source works.
Ancient Fortran should not be that hard to convert, especially if you
know the original platform. I saw LIB$ calls, which leads me to
believe this was maybe VAX Fortran? I see the use of FORMAT
specifiers without lengths, like F, not F7.2. It would be nice to
know the precise meaning of that non-standard Fortran. But, very new
Fortran sill also accept FORMAT specifiers without lengths now. And,
there is non-advancing support for Fortran I/O now. Fortran
INTRINSICS should be straightforward. The library calls will be harder.
Want help? What platform do you want to run the code on?

I have an original printout of Adventure from the mid 70's, taken
from a Vax though,
It's not a version I've found on the archives, the version ID on mine
is different.
I've been meaning to scan it and post it.
Ancient fortran is very hard to convert, as I found out trying to
convert trek7 (https://trek7.sourceforge.net
<https://trek7.sourceforge.net/>)
And I spent 38 years or so converting "the new castle" from Vax to
Linux/Dos/Mac.
Dan.
