Went to an estate sale (about 20 minutes walking distance from here) and grabbed a total of 8 home-recorded VHS tapes. There were several more as well.
Tape 1 - "The Wizard of Oz" (1939) taped from CBS/KIMA-29 Yakima on March 19th, 1989 with commercials; also includes three episodes of Lap Quilting with George Bonesteel (first one is partial) taped from KYVE-47 Yakima circa 1987, including most of a TV Worth Watching/Public TV promo (This is my oldest Yakima footage so far!)
Tape 2 - "The Ten Commandments" (1956) taped from ABC (KAPP?) around 1989 minus ads
Tape 3 - A dud! First seven minutes of pre-race footage from the Talladega 500 (taped in July 1987 off CBS), and the rest of the tape was blank. A real shame. Must have been erased by the owner.
Tape 4 - Several hours of CBS Winter Olympics footage from Lilliehammer, Norway, taped 2/23/1994 from KIMA-29 Yakima with commercials
Tape 5 - Several hours of CBS Winter Olympics footage from Lilliehammer, Norway, taped 2/25/1994 from KIMA-29 Yakima with commercials
Tape 6 - 1988 Daytona 500, taped from KIMA-29 Yakima on 2/14/1988 with commercials
Tape 7 - A few hours of CBS News coverage from 2/23/1991 taped off KIMA-29 - the beginning of the ground war in the Persian Gulf, with Dan Rather reporting from Saudi Arabia; includes some commercial breaks.
Tape 8 - 1991 Indianapolis 500, taped from KAPP-35 Yakima on 5/26/1991 with commercials. Might be another dud however, as the audio goes in and out quite often (as if someone was stuck on the volume control). The first commercial break seemed to have video, but zero audio. Probably not a technical problem at KAPP or at the ABC network.
Also found but didn't pick up - Two tapes with Ken Burns' "The Civil War" (1991), "Meet Me in St. Louis" (1944) with Judy Garland, "White Fang" (1991) with Ethan Hawke, "Top Gun" (1986) with Tom Cruise, already have an original retail Paramount HV tape of that movie; "Driving Miss Daisy" (1989) with Jessica Tandy (already have a Warner Home Video copy of that movie), and a bunch that were unlabeled - some looked unused, others were stopped about a minute in.
