So… I’m presently digitizing the last home-recorded tape.
Turns out that after the home video shot at the Guggenheim (!!) … there is a recording of a TV movie that aired on the ABC television network. While the reception of WABC was poor/fuzzy/ghosty, the Line 21 caption data is coming through just fine.
Wasn’t expecting that, but a nice bonus to have more ABC network material. 😂
