 In my case it's been more than 40 years, but ISTR a duplicater in which
you'd insert the "bent, spindalled, mutilated card " and a blank card and it
would copy(punch) the defective card. You'd only have to go to the adjoining
keypunch room to get it made if the card was totally beyond repair and wouldn't
feed in the amazingly forgiving duplicater. Mind you since the punch card room
had some 20 operaters(x-typists) all female including my current girlfriend of
the time, we found many cards unable to be duplicated.
 I don't remember any of these machines also able to print info on the cards,
which would stand to reason since all of them had data which wouldn't fit in
the top space. For that we used the interpreter wired to print the identifying
