first computer on the moon
By Apollo 11 we had a desktop computer, sort of, kind of, called an Olivetti Programma 101. It was a kind of supercalculator. It was probably a foot and a half square, and about maybe eight inches tall. It would add, subtract, multiply, and divide, but it would remember a sequence of these things, and it would record that sequence on a magnetic card, a magnetic strip that was about a foot long and two incehs wide. So you could write a sequence, a programming sequence, and load it in there, and the if you would - the Lunar Module high-gain antenna was not very smart, it didn’t know where Earth was. […] We would have to run four separate programs on this Programma 101 […]
