My very first job after finishing graduate school was helping devise a way to manufacture retro electronic replacement parts for B-52s. B-52s were built using components that were state of the art at the time, but haven't been manufactured in many decades. The SAC had a large stash of replacement electronic parts in salt caves in Utah, but those were projected to be depleted by 2000 or so. There were studies about re-engineering the avionics, but they concluded that would be require too much testing, so launched a program to recover the ability to manufacture old parts. My personal involvement was in the remanufacture of a chip first sold in 1969 but available to Boeing for B-52 upgrades in 1968, the Intel 1101 SRAM. We sort of succeeded, but before long the machines involved in the manufacturing process were themselves obsolete and unmaintainable, and the Air Force decided to do it some other way. I was reminded of a science fiction story from my youth in which there was a battle between an army with jet airplanes and an army with pikes and poison darts. Then I was no longer able to buy mercury batteries for my Rollei 35; the problem had hit close to home.
