Duping decks was also necessary for backup, and after a while for wear.
Depending on what you were doing, there WERE plenty of times when punched
cards would be the OUTPUT for a job.
I liked keeping things on a friendly basis with operators. My output
went mostly to tape if not printed. The operators that I knew hated
the punch and often wouldn't even check to see if any output had
stacked up.

The CDC 405 (1200 cpm) when it jammed, produced the most delightful
accordion-pleated cards. A joy to origamists everywhere.
