Worked on the B52 electronics 1971 thru 1975 in North Dakota and upstate NY.
At that time they used mini vacuum tubes. Produced a lot of heat.
Took apart a radar monitor one time and found a fried mouse.
Saw them go to transistors then integrated circuits with infra red and and video cameras.
The older models were used in Guam and N. Vietnam.
Those had a periscope bombing sights like the WWII planes.
Do you know if they’re considering (again!) 4x big high-bypass engines, or 8x smaller ones?
97 AMS 1981-85. Lots of tubes, synchros, servos, and mechanical computers.
