Super-8 video film was introduced in 1965.
8mm had existed prior to this, but it had not been popular with the public. The format was cumbersome in it’s original iteration.

Heh, looks like they didn't consider that. Of course, it might have been the older 8mm, and the source doesn't know any better.
However, while this is interesting, I doubt it. When did any hospital chart have what looks like a picture from a portrait studio?

Kind of off-topic, but the feature-length film “A Polish Vampire In Burbank” was shot entirely in 8mm.
Ya can’t make this stuff up!
