I suspect that the military also has a fair number of
them. A couple
of years ago, I duplicated some RX02 floppies that were used in a rig
for maintaining C130 transports.
Not 8s - they were never very popular with the military, even though
Straight-8s were tagged with JETDS nomenclature of AN/GSQ-something.
During the very early 1970s, I think Novas claimed most of what ground
the PDP-8s would be good for.
