I have created a Civ 1 tech tree that fits on a 8.5x11 sheet of paper. You may find it at:
http://mywebpages.comcast.net/pmm1/games/games.html
It is available both as a native file format (PowerPoint 2000) or
as an Adobe PDF.
By the way, on the same page there are 1-page tech trees that I have created for Civ2, X-COM, and Alpha Centauri (inc. Alien X-fire) as well as other useful reference files, including a comprehensive summary of the techs for Space Empires IV Gold.
