The CDT, Mr. Magnan -- the whole scenario is straight from Laumer's work. Fan fiction inspires all great things :)
I don't think it was ever "lost", it just became gradually more obscure over time, as most things do.
Edit: Looking closer, I see that Langston's 1980 distribution also included Empire (PDP11 object files, not source! -- infamously), "Fast Food" (with C source), and "Star_Drek" -- object files again)
Just a reminder, the ESA would like to make this a crime.
Edit: the source was retrieved from the original author. I stand down.
If you want to try your hand at another obscure, early text adventure, there's a version of Warp (early 1980s) hosted here:

(You have to access it through telnet.)
It's a huge game with a very advanced parser, but it only runs on the HP e3000 and the source code has never been released. This is another one I'd like to eventually see the source code to, but I tried contacting one of the authors and got no reply.
