Eh, i skipped the whole 5" era - i guess i saw them as too fragile. i developed and wrote my dissertation on 8"ers (mostly the "newer" ones with a capacity of 1MB). But i also, in that same endeavor, used a TTY for I/O and used its tape punch (by holding the tape still) to edit snippets. Of course earlier i used to play sonnets on an IBM 1620 (which was free for use after midnight) with sorted decks of Holleriths. To edit them i would use the adjacent keypunch (also holding to edit).
