And it wasn’t just a 4KB “stick” of RAM or something, it was literally magnetic rings threaded onto wires called Magentic Core Memory. Further, 4 KB implies that it was 4096 bytes, but it was actually 2048 “words” consisting of 15-bits (+1 parity bit) [source]. 2048 words requiring 16 bits each means 32,768 magnetic rings weaved onto tiny wires. Oh, and another fun detail about magnetic core memory is that if you read a value, I.e check to see if one of those magnetic rings is set to 0 or 1, that is a destructive operation. So if you wanted to read without deleting, you have to read and then immediately rewrite.


Is this one of those “toxic relationships” I’ve been hearing so much about lately?


I didn’t know either so I put it through tineye. It’s David Koresh


I looked it up so thought I’d share
