I have created an Excel spreadsheet summarizing the tech levels and areas for SEIV Gold. It is available on my website (as well as in Adobe PDF format) at:
http://mywebpages.comcast.net/pmm1/games/games.html
By the way, on the same page there are 1-page tech trees that I have
created for Civ1, Civ2, Alpha Centauri (inc. Alien X-fire), and X-COM as other useful reference files.
