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.

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. alan On 2/3/18 2:00 PM, Larry Baker wrote: 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'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.
