Beschreibung:

Apollo Guidance Computer read-only rope memory is launched into space aboard the Apollo 11 mission, which carried American astronauts to the Moon and back. This rope memory was made by hand, and was equivalent to 72 KB of storage. Manufacturing rope memory was laborious and slow, and it could take months to weave a program into the rope memory. If a wire went through one of the circular cores it represented a binary one, and those that went around a core represented a binary zero.
