I remember DECtape. The first computer on which I seriously worked
and developped Data Aquisition programs was a PDP15, equipped with one
or two DECtape drives. These were large and rather short tapes which
were formatted like disks. It was fun to watch the tape moving nervously
back and forth between the two small wheels.
