    oh that is absolutely fascinating to see in detailI wonder if the very low density (relatively speaking to today) make them more robust against gamma-rays and other radiation problems once outside the atmosphere?if I remember correctly, and it's been decades of coursefour of the computers ran in parallel with the exact same instructions in case one failed or came up with a wrong answerand the fifth computer was the "decider"is that understanding correct?ah I see now you mention Eight networks were assigned to flight-critical systems, with each CRT display and engine controller connected to four networks for redundancy.
