Description:
Used on every moon landing mission for onboard guidance and navigation.
Apollo Guidance Computer: Original Display and Keyboard (DSKY) Unit. A fifteen pound, 8" x 8" x 6.5" 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, but it can be yours for a fraction of that amount! Very good condition with some various surface scratches and wear from use. Not tested.

The metal plate with a NASA logo on the back surface includes the following information: "APOLLO G & H SYSTEM", "PART No. 2003985-021", "SERIAL NO. RAY 3", "CONT. NO. NAS 9-497", "Designed by M I T Instrumentation Lab", "MFG BY RAYTHEON CO." Beneath is printed "NASA NO. 2003985-021 X", "MFD BY RAYTHEON CO.", and "SERIAL NO. RAY.3". Included with this lot is a printed document titled "Disassembly of the Apollo Guidance Computer."

There are many great websites with incredibly detailed information on the AGC and DSKY as a Google or Bing search will reveal. One of our favorites is a site with a DSKY simulator.
