"Hand operated card punch..."? Back when I was training on our brand new IBM 360 Mark1965, we were pretty advanced--we used an IBM 026 Duplicating Keypunch. Might even still have my Certificate in Competence. I do remember feeding in the punchcards to get the operating system going and if the cake pan shaped RAM wasn't in, seeing the printout, "Put in the disk, stupid."
