One of our favorite retro hardware enthusiasts, [CuriousMarc], is back with the outstanding tale of preserving Apollo Program software, and building a core rope reader from scratch to do it. We&#82… ...

If you want read-only memory today, you might be tempted to use flash memory or, if you want old-school, maybe an EPROM. But there was a time when that wasn’t feasible. [Igor Brichkov] shows … ...

Again, the moon missions demanded a stable and compact way of storing Apollo’s computing instructions. Core memory used metal wires threaded through tiny doughnut-shaped ferrite rings, or ...

The overall memory of the Apollo Guidance Computer was equivalent to 72kb (in modern terms) and the software had to be woven into the core rope memory, women in factories put the software together ...

That core memory works out to 32,768 bits of RAM or 72KB (equal to 589,824 bits) of ROM. How does that compare to a modern smartphone? As Cult of Mac notes , an iPhone with 4 gigabytes of RAM (that’s ...

Signals from seismic sensors left on the lunar surface by Apollo astronauts in the 1970s have revealed new insight into the moon's core, thanks to a fresh analysis using 21st century computing power.

On Apollo 1, during a launch rehearsal test on Jan. 27, 1967, all three astronauts on board — Gus Grissom, Ed White, and Roger B. Chaffee — died when a fire swept through the command module.
