It is hard to appreciate the technical challenges involved in putting a man on the moon, but 1960s computer technology played a fundamental role. No purchase necessary. The Gemini mission referred to is Gemini 3, which was the first manned flight of the Gemini program that flew for just 4 hours and 52 minutes in 1965. Rare Wozniak-Jobs "blue box" phone phreaking device could fetch $100,000, Important Sci-fi and Movie Memorabilia heads to auction, Michael Jordan's backboard-shattering sneakers sell for $615,000, Another set of Air Jordan sneakers sell for $475k, record could hit $850k, Chinese quantum computer completes 2.5-billion-year task in minutes, Massive 853-foot-tall wind turbines are coming to America's East Coast, Printable, flexible battery offers 10 times the density of lithium-ion, New method quickly converts natural gas into solid form for storage. The machine, made by Hewlett Packard Enterprise and called the Spaceborne Computer, is capable of a teraflop worth of computing power, which puts it roughly in line with a late-1990s supercomputer. The 4.25-in (10-cm) "memory chip… But it scared him and he didn’t want to tell anyone else in the USA what he had.”, But he would tell Rautenbach, who traveled from Tshwane to Houston last year to play with the groundbreaking computer. © 2020 Atlas Obscura.

It was rescued by a self-described “perpetual hacker” from Tshwane, South Africa named Francois Rautenbach, who not only identified, verified, and fixed up the computer, but also recovered the software used during the AS-202 launch, reported Gadget.co.za. This article was a trip down memory lane for me...Both my wife and I worked on core memory way back in the 60's for Control Data.. In addition, he is the author of a number of websites, four award-winning plays, a novel that has thankfully vanished from history, reviews, scholarly works ranging from industrial archaeology to law, and has worked as a feature writer for several international magazines.

The company introduced several technologies Cray invented that became central to supercomputing, including immersion cooling and vector register technologies, with the development of the CRAY-1 in 1976 and the CRAY-2 in 1985. It successfully led a rocket in and out of suborbit, paving the way for the mission to the Moon. See the stories that matter in your inbox every morning. These wires magnetized the rings and read the memory. Rautenbach had become interested in the Apollo Guidance Computer (AGC) after reading up on it challenged his own assumptions. It was the first manned spacecraft to maneuver and change orbit, and the only one to include a smuggled corn beef sandwich – which got the crew into a lot of trouble with NASA. But until very recently, it wasn’t. A Hacker From South Africa Rescued the First NASA Computer in Space. The memory plane on auction is a ferrite core memory, which was common in computers from about 1955 to 1975. The problem is that the book misses the whole Section 8 (about 290 pages long) devoted to Guidance and Control System, perhaps the most interesting aspect of the Gemini missions: the first rendezvous missions, the first orbital maneuvers, the first computer in space (manned S/C) and so on. The whole heap was then sold at a scrap metal auction to a man in Houston, who wishes to remain anonymous. Rautenbach says that even as this hardware and software inspired future missions, the stuff itself—the circuits, the modules—ended up in a trash pile, surrounded by junk. He then had the memory modules shipped back to his workshop in South Africa, so that he could extract and rebuild the software. Weighing 8.98 pounds (26.75 kg) and taking up 1.35 ft³ (3.82 l), the Gemini computer was tiny compared to many of its Earthbound counterparts.
