The Weavers: Memory and the Moon

In 1965, engineers were building a computer to fly men to the moon. It had to survive a rocket launch and the vacuum of space. It could not be erased by a power failure, a hard landing, or anything short of physical destruction. They needed to make the code permanent. They needed to weave it.

In this episode

• Hilda Carpenter - MIT technician who assembled the first magnetic-core memory plane
