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

[Alan Perry]

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.
