Doug Bonaforte, coauthor of the Star Explorer board game (companion game to Starships and Spacemen), read my review, and went and found his unpublished addenda/errata for S&S... he's uploaded it to BGG...
I had a copy of Star Explorer decades ago (I recognize the cover) but I recall essentially zero about it. In general, I found FGU games to be less organized and more complex than OD&D, so I gave up on them. I can't say that SE fits that description, but the fact that I can't recall anything about the game says something.
However, should I ever run into SE again it's nice to know where I can get the additional rules. Thanks for the link!
