    As used on every moon-landing mission for onboard guidance and navigation

    Apollo Guidance Computer: Original Display and Keyboard (DSKY) Unit. Not flown. An eighteen pound, 8" x 8" x 7" M.I.T.-designed and Raytheon-manufactured data entry and display device with nineteen keys and a twenty-one digit display. A unit like this was mounted into the control panel of each lunar module and two were found in each command module. This was the astronaut's interface allowing access to the groundbreaking Apollo Guidance Computer, developed by MIT, on board. It permitted the astronauts to collect and provide flight information and was very important in the precise landings on the moon needed for a successful mission. Each different program had a two-digit code and commands were entered as two-digit numbers in a verb-noun sequence. These units were also used on the Skylab missions and adapted for an experimental fly-by-wire system for the F-8 Crusader. It is impossible to overestimate the importance of the DSKY interface and the AGC to the Apollo moon landing program. A very rarely offered piece of Apollo equipment; purportedly only about seventy-five were ever made. This cost the government more than $200,000 originally; it'll be interesting to see what this one sells for. Not tested. Fine.

    The metal plate with a NASA logo on the back surface includes the following information: "APOLLO G & N SYSTEM", "PART No. 2003994-121", "CONT. NO. NAS 9-497", "Designed by M I T Instrumentation Lab", "MFG BY RAYTHEON CO." Beneath is printed "MFD BY RAYTHEON CO.". We note two NASA inspector's stamps.
