Key punch? Oh ya. I have kept a couple of complete program decks for all these years hoping that my kids would appreciate them and the stories they evoke in my memory. I gave my son (CS major deep into artificial intelligence) his deck as a Christmas gift. 120 cards of a FORTRAN 77 program. He shows it to his friends all the time - keeps it on his dorm room desk. I’m saving another for my daughter - when she gets to college.
