How many GB's in the computer that sent man to the moon?

Answer 1

The mainframes at NASA had more than the spacecraft-- they did the real work. I don't know the specifications of the mainframes.

The on-board DSKY computers, first to put the CPU on a chip, and thus the ancestor of the computer you are using now, probably had no more than thousands of bytes. It was a very simple number-only computer. Even actions were input as numbers. The keyboard had a Noun button and Verb button-- you input whether the number in question was to be a "thing" or an action.

There are people whose hobby is to build replicas of this computer. They have even dug out the original software to use in it. It is a very limited computer, but there is no doubt that it was able to do the one job it was built for.

It was a very limited computer, but it only had one job to do-- guidance. It either obeyed numbers relayed to the astronauts and hand-entered, or from data supplied by the radar system. The CSM did most of the work of linking up to the LMs after they left the Moon.

Answer 2

The computer on Apollo 11 that sent humans to the moon had a total memory of only 64 kilobytes, which is equivalent to 0.000064 gigabytes. This computer, known as the Apollo Guidance Computer, was a groundbreaking technology for its time.
