Notice the integrated circuits, they are all early ceramic type with date codes of 1970 and 1971. This from Francis Sheehan who was an engineer at NASA for many years. He primarily worked on manned fight missions such as the Gemini project and several of the Apollo missions including the Lunar Excursion Module (LEM) and the Shuttle program. He was located in several locations during his work.
