some 6H30s in my ARC preamp.
Thanks to inmate Victor K. for introducing those and 6C33s to the audio world. :)
at least as far as a manned landing on the moon.
The computer necessary for control of the lunar lander used chips made by Rockwell Semiconductor (they called them ELSIs or LSIs at the time) with 40 pins. The Soviets had no computer technology snall enough to fit inside a landing craft and the time delay between earth and the moon was too long for earthbound computers to be of any use.
Those Rockwell chips?
Shortly after the mood landing that technology, paid for by American Tax Dollars, was sold to the Japanese and came home to us as Sharp electronic calculators
IBM was the supplier and used a large System/360 for tracking purposes and a custom hand built module using core memory for the onboard instrument section.
Here's a video with one of the former engineer's explaining its operation:

In late seventies, we used a NASA mainframe with a program called NASTRAN for some of our Finite Element analysis of structural slab systems. We had little terminals into which we fed our punched cards and the results came from Omaha. The girls used to make mistakes in the punching and the whole thing would bomb. It was tough to find good punchers so nobody was let go! The Space Frame analysis was what I loved most.
Cheers
