Mary Ann Horton scripsit:
But we never had dectapes and I think they did their
own blocking.
Indeed. A DECtape (aka microtape) was logically speaking a floppy disk
sliced into cylinders and then concatenated. As a result it was possible
to rewrite any block without affecting later blocks, something not true
of conventional ("macro") tape.
My first system, a PDP-8/M, used a single DECtape drive as its system
"disk"; the second system, a PDP-8/A, used an 8-inch floppy.
