Finally discovered. I was going through some tapes, and thought that I had reached the end of what we've recorded (in 1988). I let the tape go for a few seconds, and sure enough, something popped up: The credits to a miniseries called "Kennedy" and most of the 11 o'clock news from that day. That day happened to be November 21, 1983, apparently the 20th anniversary of the JFK assassination. West Germany was still a country, KUPL played easy listening instead of country, and Darryl Strawberry was named NL rookie of the year. And you could get a brand new 1984 car for $8115. OK, so it ain't the Zapruder film, but I'll take it.
