What kind of setup displays the network, time and date at the top of the screen?Good question. Video capture was more primitive in those days. lol
Vanderbilt has an archive of old newscasts (link below) and it does list this as a topic for ABC on Jul 2, 1982. There is a fee to check out the tapes so I can't see if it's the same as on youtube.
