3340 DIAGNOSTIC DISKETTE **M.T.=5412**
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.

Did it not also introduce the 8" DSDD drive and diskettes? Is the index
hole on these at about 1:30?

Gee . . . How does that square with the age-old tale that the term
winchester came from their model 3030?
