Nostalgia Air is, for a free service, very good. Unfortunately, some of the scans were of poor quality. It seems that the site was in the process of being upgraded at one time with better scans. Unfortunately, the site originator has passed on. Still in all, I'm very VERY thankful for the site's existance, since there are a large number of schematics that would otherwise have gone the way of the dinosaurs.
