I think I've acquired another "Homebrew" item.  This one is entitled "Generic Science Fiction Role Playing Game".  It is 17 pages of a continuous feed printout (still connected).  I've looked it over and it appears original (I've never seen it in print anywhere before).  I'm posting some scans, so if anyone recognizes anything, let me know.

I'd guess it was from about 1980-81 as it arrived in a Dragonquest 1st edition box set (other items from the same lot include Barbarian Kings, Basic Rules - Otus cover art -  and Thieves's World 2nd edition box set).
