yeah it's completely totally different.
the original code was from PDP, but written by Donald Ecclestone at UWO 
(Western) in London Ontario
I started helping him out with the code in 1978 just when he ported it over to 
the vax.

There's some time-restricting code in it to prevent students from running it 
during class hours,
But normally it's left disabled.

There's some internal debug stuff still left in as well.

Donald wrote a TREK5 which was pretty classic trek game, not multi-player or 
anything, but I don't know if he created it or based it on common code elements 
available at the time.

Subject: [Simh] Trek FORTRAN games (Was: Crowther's Adventure game)

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.
