EDRUPT - My Speakers
Special web release for an electro track by me.
The story of EDRUPT is an esoteric mystery of NASA’s Apollo moon missions. Did you know that the Apollo Guidance Computer (AGC) was the first computer built with integrated circuits a.k.a. chips? Containing 4,100 chips strung together by hand with wire wrap and solidified inside clear epoxy, the AGC was used in all of NASA’s manned moon missions. Details of its operation have been disclosed, but one of the computer’s designers included a strange and poorly documented machine instruction called EDRUPT. It was used only once in the mission, during the phase when the Lunar Module made its descent toward the moon’s surface under digital control. Retro computing enthusiasts can simulate the AGC’s Luminary 131 software on desktop machines but its found that the system breaks unless EDRUPT is removed from the code. One understanding of EDRUPT is that it instructed the computer to send data to an unknown destination elsewhere in the spacecraft. But why is EDRUPT a missing piece of the puzzle? What was contained in the data it sent? And… what or who was the intended recipient?
