I'd love to see this happen. I started off taping them, but then gave up and didn't even save what I had.
This might seem a silly request, but there was one episode of this Sci-Fi run (and unfortunately I don't remember which one) that aired the original art card (of the Enterprise in orbit around a planet with the ST logo beneath) that exists on the negatives after the opening credits. It's silent, to allow room for a network audio cart to be played on air of an announcer saying "Star Trek, brought to you by"...at which point an ad would have been spliced in.
The card lasts maybe 4 seconds, and seems odd and out of place in a modern context, especially without an announcer. It's the only time I've ever seen it aired, (not being quite old enough to have watched the original network run), and to me is an interesting document of how the episodes were delivered to the network. So, if and when you're digitizing the intros, please zip forward though the credits and see if you can find the one time this happened, and preserve it, too.
