Learning to program on punchcards
I wasn't born in the era, but I'd like to experience writing a program with punch cards.
Does anyone know of a program or an online simulator, so I can relive some history?
Punch cards are just a storage medium. You could store a program on punch cards, but once you put them in a card reader, the processing is just like it would be, reading from tape or disk...just a lot slower. As such, there's not really anything to emulate.
In the days before CLI editors, you started your programming with pencil and paper, and once you had written your code, you walked your notes over to a card punch machine, which looked much like a typewriter, and you typed in your code. The cards come out of the punch, you load them into the computer's input hopper, and load them into memory, then execute.
