Punched cards! New fangled idea. We used paper tape punched on teletype machines. .

Of course it was new, but then I am much younger than you, John.

As an operator I used to keep a set of punched cards next to the main console and when new programmers brought me their decks of cards for compilation, I would sometimes switch their decks with mine. It was hilarious to see their faces when I 'accidently' dropped the whole deck and they would have to spend hours sorting the cards into sequence again. They learned after a few of these to simply number the cards with a pencil.

I know.... geek humour.
