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
@sungo That's badass!
@cypnk This is cool! Thank you for sharing
@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
@cypnk Will do! I blame you for all the procrastination I will undertake this weekend, though
@Orwellia @cypnk You can visit some core memory at the Computer History Museum in Mountain View, California. http://www.computerhistory.org/revolution/memory-storage/8/253
@cypnk
I wonder if the people who were specialized in magnetic cores succed to evolve when silicon taked the lead !
The architecture should be (quite) the same :D
@cypnk A professor I had in college had a necklace of core memory.
