I second this - and am happy to see an ipdb.org link - there is a ton of information there. I picked up an old Xenon - http://www.ipdb.org/machine.cgi?gid=2821 - worked it over with guides online and it still runs great 10 years later. If I had the room I'd have more!

Thirded. One of the most satisfying restorations we've ever done was a sand-it-down-to-the-wood repaint/restore of a Space Shuttle. There's an extra level of satisfaction to play a machine where every screw, bolt, wire, and switch is something that you personally put in place.
