I can offer 3 ideas:
1. The
collegebowl.com website used to have nearly all of the shows
listed by air date, with the names of the teams (though
not always the scores) listed. That's how I found
BYU's appearance in '62 and how they did. Maybe even if
they don't have the videotapes, they could at least
resurrect the list I mentioned and you could fill in a few
more that way (though there is a gap from late spring
to fall every year because the show was always on
hiatus for the summer).
2. Try the professor who
runs tvgameshows.net
3. Try the Museum of
Television and Radio in New York City, as I have heard they
have a few old CB tapes available from individual
shows that you can pay to watch at the
museum.
Good luck! It sounds interesting!
