I downloaded the entire broadcast and spent a few quality hours looking at it as a retired broadcast director with a great sense of this history and a few too many hours working in the environment. Please excuse the diversion from the pure TK discovery to my observations on how ABC covered this game in my broadcast world.
I had to first count the cameras ABC sent to this show in Iowa. I count eight (8).
They are;
Sideline left 35. Used as game coverage. The usual wide shot.
Mid 50. Game camera. Same wide shot.
Mid 50. Tight shot camera. Also hero camera
Sideline right 25. Game camera on the same wide shot.
End zone. Kicks, clock, generic shots.
Sideline approx Right 35. Low on a platform. Does not appear to move.
2 field handhelds. One on each sideline. Camera unknown but not TK. Much warmer color. Thinking Philips.
Far sideline is seldom used. Pic below for help in ID.
One looking ok, the other with registration problems.
Replay. Seems to be a pair of Ampex HS-100 30 sec. disc recorders. More on this
web page.

A massive sideline microphone. Sometimes a spiral series of tuned tubes in to a funnel to the pickup. I forget
manufacturer.
ABC had all the camera tools there to do coverage and was moving to the sophisticated coverage we know today. I was surprised to see the 35/50/25 yard line setup. I thought that came later. Single announcer that I cannot ID. A second color announcer is heard for a few seconds. Sounds like phone line audio. They mention three other regional games going on. I am wondering if the zoom lens optics were a bit tighter on the tubes to eliminate the usual corner problems.
Will correct if needed. And slave to two cats. Help find more of these ancient quads.
