Amazing. Punch cards are before my time but did she have to plot out the code before creating punch cards? I'm wondering about the " by hand " part of it.
I was a CS major in late 70s and used punch cards for Fortran programs. I’m guessing “by hand” meant writing the code with pencil/pen on paper and then typing up the punch cards for each line of code.
As @hjeremy@lemm.ee noted, this was woven into core rope memory, not punch cards.
Oh that sounds neat. I'll go look that up as i haven't heard of core rope.
Alright that was cool. Thanks for the link. I barely understood how it works but sort of got the concept. How far we have come. Wow.
There was a keyboard involved. They don't use a hole puncher lol.
I was just grasping at straws. Kinda wanted to know more as it sounds like a good story.
