Description


Rare electroluminescent display screen from a Block II Apollo Display and Keyboard Assembly (DSKY), measuring 3.25″ x 4.5″ x 1″, attached to a mounting bracket, marked on the reverse: "NASA Part No. 1006315-001, Rev. C, LSI Part No. 142882-001, Ser. No. 340A." The front of the screen has black text identifying the computer activity status light ("Comp Acty"), program number display ("Prog"), verb code display ("Verb"), and noun code display ("Noun"). This unit remains sealed in its "Controlled Cleanliness Article" bag and is accompanied by a Raytheon inspection booklet marked "Acceptance Data Package, Apollo/EL Light & Cover Assy, Part No. 2003988-021, Serial No. 340A." Also includes its padded blue shipping box. In fine condition.

The DSKY was the main interface between an astronaut and the Apollo Guidance Computer (AGC), which controlled the Apollo spacecraft. Each AGC program had a two-digit code displayed on the screen, and commands were entered via a numerical keypad as two-digit numbers in a verb-noun sequence. It was the DSKY that provided the astronauts with critical burn times for engine firings, course corrections, trajectories, and other key calculations vital in getting a crew to and from the moon. The DSKY also reported the program alarm moments before the LM touched down on the lunar surface on the first lunar landing. DSKY units are among the most recognizable and historically significant of all Apollo spacecraft parts—this screen, designed to provide mission-critical information at a moment's notice, is a superb piece of spaceflight history.
