NASA AERONUTRONIC PROJECT MERCURY orig. photos documents specs ONBOARD COMPUTERS

Description

This is an original Project Mercury binder from 1961 with about 140 pages of original photographic prints, signed and initialed memos and documents, handwritten notes and documents, typed documents marked-up with editing in pencil, handwritten and copied graphs, circuit diagrams, and other technical data (copies are with an early form of xerography), and product specs. All dealing with John Glenn's Project Mercury flight, specifically with the onboard computers and electronics for flight.
All in a vintage black 3-ring binder.
Photographs include electronics engineers testing the onboard computers, including from inside the rocket wearing their socks to avoid damage.
Letterhead on the documents is mostly from the Aeronutronic division of Ford Aerospace in Newport Beach California, which had a major role in the flight. Many names of known project engineers are in these documents, sometimes personally signed or initialed.
All the dates are in 1961.
An important set of documents for the history of computers in space flight.
The names on the documents are all over the internet as authors of scientific papers, linked with the astronauts, and other connections.
CONDITION
Note that the wavy lines and color reflections on the black and white photographs are reflections on the plastic of the old sheet protectors.
Some rust on 3 ring binder posts, paper toning but still very legible and not fragile.
A one-of-a-kind item. A museum piece, really.
