The Internet Archive Magazine Rack has 25 issues of The Space Gamer (later titled Space Gamer/Fantasy Gamer). This started out as Metagaming Concept's house zine, and then later was handed off to Steve Jackson Games and then later spun off again and now seems to be stuck behind a paywall at a website that seems to have been designed in 1995 (although the forums seem to be active).
Anyways . . . I flipped through the issues available from the Internet Archive and found a few adventure scenarios that might be of interest to old school gamers. I've linked to the issues in the Internet Archives AND I've extracted the relevant pages from the PDFs of each issue for easy access, and those extracts are hosted via my DropBox account.
AD&D Scenario - A Plague in Westerbrook
Paranoia Solo Scenario - One of the Best PARANOIA Mini-Solo-Adventures Ever Published (small ruleset included)
AD&D Tournament Scenario - The Halls of Fortune
Star Wars d6 Scenario - Death of a Hero
Note: This issue was the first issue after another change of ownership, and it is paced with sweetness. In addition to the extract I've posted, there are two GURPS scenarios, an interesting article on "Luxorian Triplets for AD&D" & a new monster, the Dreadguard, both by James M. LeDuc. There's also a great "Universal Bar Generator" by Bill Burg, and an article detailing 50 arcane tomes for Call of Cthulhu by Christopher Pound, and an interesting article by Gary Reilly on integrating sci-fi weapons into fantasy games. If you are going to download an entire issue, make it this one.
AD&D Scenario - Pieces of Honor
Gamma World Scenario - Plague on Umbril River
