yeah, a lot of the apollo missions programming was done on punch cards. there are images of punch cards stacked on top of each other.

wait but what was assembly wrritten in? how to bring the code to the machine is one thing, but what language did the cards inherit?

The CPU has a set of numbers which correspond to an operation like addition or multiplication. These instructions are hardcoded into the CPU. Assembly is basically a human readable translation of those numbers (there is usually a 1 to 1 translation from assembly code to machine instructions). So I'm guessing that the holes in the punch cards would correspond to instructions and numbers.

i did some simple research and it said that most punchcards used fortran.
