And this:

Don´t EVER forget that the WHOLE Apollo project was calculated by these!

Actually they had some electromechanical computers those days, but they were pretty primative.

On that subject - if there weren’t any transistors, we would be doing calculations on these little babies:

That is a Curta calculator. Developed by a death camp inmate during WW2, it’s a marvellously compact totally mechanical calculation device, capable of some stunningly complex functions. Still available for sale, too, though I can’t justify buying one.
