That stack of 62,500 punchcards represents 4.5 MB of data circa 1955. I remember my dad doing his CS homework/projects on those things in the early Seventies! Today, my current iPhone Xs holds over 14,000 times that much information and it’s the size of a pocket calculator, keeping up those Seventies’ references. I was going to say a cigarette pack but I don’t smoke and I think those are shorter.
All those punchcards! Must have been hell keep them all in order and moving them about or worse, imagine a bug hunt with them!
