Well that brings back memories!
I spent lots of time with FORTRAN and assembly language on the IBM 1130 and 360s in the days.
I still have the habit of having a small paperclip on my shirt pocket from spending hours at the keypunch and reader. Paperclip was used to unclog the card vacuum pickup arm...
I also had a paper clip but for a different reason. I helped to fit punched out pieces back into the holes if we needed to fix something quickly. Yes that's how backspace worked back in the days. :-)
Not early computer oriented, but your comment reminded me of when we sent a daily report via Telex.
To this end, we had a teleprinter & a tape reperforator.
The normal method was to type up the report & produce a tape, then run the tape to send the message.
There was a lot of stuff which didn't change day to day, so we would make up short tapes with such things on them, stop composing the day's message where they fitted, run the short tape & add the information to the daily tape (our setup could do that).
We were pretty much doing "cut & paste" in an "old school" way.
We were also required to keep each day's tape for several days, so along with the above mentioned "short tapes", it added up to a fairly messy pile of them on the desk.
One of the guys became sick of this, & I came in to work one morning to find them all attached to the felt notice board with thumbtacks.
"Gee, that's neat", thought I, & didn't think anymore about it, until we tried to run one of the tapes, when we found a problem.
Perforated paper tapes don't like having extra random holes added!
For the tapes already removed from the board, it was a matter of taking them outside in the bright sunshine & looking for holes that didn't quite "look right", covering them with Sellotape, testing, then making a replacement.
With the undisturbed ones, it was just a matter of marking them where the pin went through, then doing the "Sellotape" thing, & so on, but the whole process still wasted a couple of hours.
