@urdailydoseofinternet28: Apollo's guidance computer ran on code that was physically woven into copper wire and magnetic rings, not stored on any disk. Engineers called it core rope memory, and it was the only way to fit a moon landing's worth of software into a machine built in the 1960s. The process started at MIT, where programmers wrote and tested the flight software on mainframes. That code was then converted into a wiring pattern, and skilled workers, mostly women with textile backgrounds, threaded copper wire through or around thousands of tiny magnetic cores by hand. A wire through the ring meant a 1, a wire around it meant a 0. One full memory unit took weeks of this work, and engineers nicknamed the workers "Little Old Ladies." The tradeoff was worth it. Because the program was physically hardwired, it could not crash, corrupt, or be erased mid flight, which mattered enormously on a mission with zero room for error. The Apollo Guidance Computer held about 72 kilobytes of this woven memory, a fraction of what a single modern photo takes up, and it still got three astronauts to the Moon and back.

dani B🥰 :

learned this on dr stone

Cameron :

Yeah and we can’t do it today🤣🤣🤣 it’s such a joke

DyatLove666 :

analog cpu??

thevampire🧛 :

nawl it's something about that I just don't feel like a human came up with that

Rangerking3.0 :

1,000,000,000%

dndns :

how does someone think of this

mammel :

shit, this is from Dr Stone wth

kaszalotek :

That’s so bad

oldschool_ET :

Also where a bug in the program comes from because a moth got into some of the earth side computer systems causing a repeating problem to occur. It literally was a bug the next system had a mesh around the hand woven chips that before the system started up the mesh would energize like a bug zapper and was the debugger. True story

The Lorax Official ✅ :

Dr stone is so peak

a.s.h.3.rr :

“Turned software into a physical object” that’s just fucking hardware😭

Pancho Lokz Marie 🏴‍☠️ :

They didn’t have an amphetemine problem then I bet

Void_Pixels :

couldn't be destroyed was apparently destroyed

文ˢⁿᵃᵏᵉʸジ :

So that could hold the original super Mario bros

Reni :

Lowkey kinda terrifying only 72kilo bytes guided humans to space

WhoamI?🧐 :

THATS AZY-CRAY

learned ts in dr. stone loll

John Smith :

As small as that is, you'd be surprised what you can do with 72 KB. That's several lines of code. What's more impressive is just how efficiently they used this data. They made every byte count. There was no room for error.

Dong Quixote :

I don’t really understand, if the copper wires touch doesn’t the electrical current just disperse into the other wire and kinda fuck everything up? I’d assume they’d need insulators or something between the wires, but I don’t really know much about electronics.

This dude :

jonels_jb_edits :

bro it's like a Dr stone

Toby "SeerSGB" Woods :

Can it play Doom?

icanbeyourjoshuamark2× :

no they didn't lmao
