From 1981-1985, I worked on USAF B-52G Automatic Flight Controls. The aircraft were late 50’s models. This Continental sounds like it was designed by the same engineering team!
The autopilot was a long series of relays and interlocks, feedback loops, and sensors.
My son in law is working on the B-52 repower program at Rolls-Royce.
I tell him it was designed with slide rules, drawn on mylar with pencil, and fabricated by high school graduates on manually operated machine tools.
