Donald Bitzer was invited on The Phil Donahue Show twice to demonstrate PLATO. The first time was around 1978. I have a copy of that video. But I am still looking for a copy of the 1981 second show, for which I believe he was sole guest, and had the entire hour to demo PLATO. (The first show he had to share with an annoying fake robot named AROK that trivialized much of the rest of the show.)

If anyone has a VHS, Beta, DVD, or other recording of the second Donahue show, please let me know (email brian at platohistory dot org). Thanks!
