Did it not also introduce the 8" DSDD drive and diskettes? Is the index

Can anyone tell me what these are and what they were for?
I don't know about the others, but the IBM 3340 was the *original*
Winchester drive. (Not "a" Winchester, but *The* Winchester.) At the bottom
of the label is what I assume is a date in the format
77/01/05 - if my assumption is correct then these must be 30 years old.
The 3340 was rolled out in 1973, but they certainly were still in service
in 1977, so that's consistent.
I'm sure the floppies are still readable; I've read many 8" IBM 3740
floppies
form the early 70's without a problem.
