These were definitely RX02 floppies--that
"funny" DEC MFM is pretty
distinctive. Maybe 11's? I've got the images somewhere here; I'll
have to take a gander at them when I get a chance.
Certainly 11s and VAX machines were more common associated with
military service. The VAX-11/785 RCS just received is ex-Sikorsky, and
spent most of its life - the latter half, anyway - writing a few
floppies a year, and nothing else.
