Testing one of the World's First Embedded Systems (1968) Raytheon test engineer Robert Zagrodnick running diagnostics on a pair of Apollo Guidance Computersą (AGC) at the Massachusetts Institute of Technology Instrumentation Laboratory (I-Lab)˛. The MIT designed 2.048 MHz 16-bit computer was 10 years ahead of its time and used integrated circuits to run a real-time multitaskingł operating system that enabled astronauts to control an Apollo spacecraft by typing simple commands on the DSKY keyboard interface in pairs of nouns and verbs. It had 2048 words of erasable magnetic-core memory and 36,864 words of read-only core rope memory⁴ with cycle time of 11.72 µs. It was designed to be fault-tolerant and was able to run several subprograms in priority order. Each of these processes was given a time slot to use the computer’s sparse resources. The computer interfaced to these onboard systems: DSKY(display and keyboard), IMU, Hand Controller, Command Module Rendezvous Radar, Lunar Module Landing Radar, Telemetry Receiver, Engine Command, and Reaction Control System.

History Fact: Beginning of the US Oil Industry On January 10, 1901, a drilling derrick at Spindletop Hill near Beaumont, Texas, produced an enormous gusher of crude oil, coating the landscape for hundreds of feet and signaling the advent of the American oil industry. The geyser was discovered at a depth of over 1,000 feet, flowed at an initial rate of approximately 100,000 barrels a day and took nine days to cap. Following the discovery, petroleum, which until that time had been used in the U.S. primarily as a lubricant and in kerosene for lamps, would become the main fuel source for new inventions such as cars and airplanes; coal-powered forms of transportation including ships and trains would also convert to the liquid fuel. In the early 1890s, Texas businessman and amateur geologist Patillo Higgins became convinced there was a large pool of oil under a salt-dome formation south of Beaumont. He and several partners established the Gladys City Oil, Gas and Manufacturing Company and made several unsuccessful drilling attempts before Higgins left the company. In 1899, Higgins leased a tract of land at Spindletop to mining engineer Anthony Lucas. The Lucas gusher blew on January 10, 1901, and ushered in the liquid fuel age. Unfortunately for Higgins, he’d lost his ownership stake by that point. Beaumont became a “black gold” boomtown, its population tripling in three months. The town filled up with oil workers, investors, merchants and con men (leading some people to dub it “Swindletop”). Within a year, there were more than 285 active wells at Spindletop and an estimated 500 oil and land companies operating in the area, including some that are major players today: Humble (now Exxon), the Texas Company (Texaco) and Magnolia Petroleum Company (Mobil). Spindletop experienced a second boom starting in the mid-1920s when more oil was discovered at deeper depths. In the 1950s, Spindletop was mined for sulphur. Today, only a few oil wells still operate in the area. http://forums.pelicanparts.com/uploa...1705953663.jpg http://forums.pelicanparts.com/uploa...1705953663.jpg http://forums.pelicanparts.com/uploa...1705953663.jpg http://forums.pelicanparts.com/uploa...1705953663.jpg http://forums.pelicanparts.com/uploa...1705953663.jpg |
