The reason we refer to "core" memory or "core dump" is because how early memory was actually designed. These are magnetic cores with wire woven through (by hand, I might add) which contained program instructions

Core memory went away when silicon took over in the mid 70s

@cypnk that's crazy that people wired those tiny magnets by hand, considering how automated things are today! Out of curiosity, where do you find this stuff?

@Orwellia Many a mis(well)spent hour on the dark corners of the internet. When I'm not killing brain cells with sleep deprivation, this is what I do ;)

@cypnk well, thank you for sharing the fruits of your labor with us! As someone who grew up with PCs it's eye-opening to see what early computing was like

@Orwellia It's a fascinating aspect. I encourage you to take a deep dive (watch out for the time!) into some forums like HAM radio and so on. There are lots of old-timers sharing photos like this
