Old school
I'm still stubborn enough to stick a floppy drive and a ZIP drive on my new machines. It costs me what now, about a quarter?
My friend Gary still has some 8 inch floppies laying around. I think we're out of luck on those. And I can lay my hands on a five-inch roll of yellow punch tape I used to program a Star Trek game into the school computer back at the university.
Those were the days, when you watched yellow paper roll out of a noisy teletype machine to see what was going on. The pinnacle of "graphics" were those Playboy models you could generate from ASCII characters. And yes, you can find them many places online now.
