The machine had a fifty-foot long camshaft running the length of machine that synchronized the machine’s thousands of component parts and used 3,500 relays. The Mark 1 produced mathematical tables but was soon superseded by electronic stored-program computers.]]> 2020-02-12 15:09:25 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444380683 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444381930 University of Manchester researchers Frederic Williams, Tom Kilburn, and Geoff Toothill develop the Small-Scale Experimental Machine (SSEM), better known as the Manchester "Baby." The Baby was built to test a new memory technology developed by Williams and Kilburn -- soon known as the Williams Tube – which was the first high-speed electronic random access memory for computers. Their first program, consisting of seventeen instructions and written by Kilburn, ran on June 21st, 1948. This was the first program in history to run on a digital, electronic, stored-program computer.]]> 2020-02-12 15:10:50 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444381930 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444384235 The first practical stored-program computer to provide a regular computing service, EDSAC is built at Cambridge University using vacuum tubes and mercury delay lines for memory. The EDSAC project was led by Cambridge professor and director of the Cambridge Computation Laboratory, Maurice Wilkes. Wilkes' ideas grew out of the Moore School lectures he had attended three years earlier. One major advance in programming was Wilkes' use of a library of short programs, called “subroutines,” stored on punched paper tapes and used for performing common repetitive calculations within a lager program.]]> 2020-02-12 15:13:25 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444384235 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444385458 IBM establishes the 650 as its first mass-produced computer, with the company selling 450 in just one year. Spinning at 12,500 rpm, the 650´s magnetic data-storage drum allowed much faster access to stored information than other drum-based machines. The Model 650 was also highly popular in universities, where a generation of students first learned programming.]]> 2020-02-12 15:14:45 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444385458 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444386997 At MIT, researchers begin experimenting with direct keyboard input to computers, a precursor to today´s normal mode of operation. Typically, computer users of the time fed their programs into a computer using punched cards or paper tape. Doug Ross wrote a memo advocating direct access in February. Ross contended that a Flexowriter -- an electrically-controlled typewriter -- connected to an MIT computer could function as a keyboard input device due to its low cost and flexibility. An experiment conducted five months later on the MIT Whirlwind computer confirmed how useful and convenient a keyboard input device could be.]]> 2020-02-12 15:16:35 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444386997 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444388900 An early transistorized computer, the NEAC (Nippon Electric Automatic Computer) includes a CPU, console, paper tape reader and punch, printer and magnetic tape units. It was sold exclusively in Japan, but could process alphabetic and Japanese kana characters. Only about thirty NEACs were sold. It managed Japan's first on-line, real-time reservation system for Kinki Nippon Railways in 1960. The last one was decommissioned in 1979.]]> 2020-02-12 15:18:46 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444388900 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444390168 The Control Data Corporation (CDC) 6600 performs up to 3 million instructions per second —three times faster than that of its closest competitor, the IBM 7030 supercomputer. The 6600 retained the distinction of being the fastest computer in the world until surpassed by its successor, the CDC 7600, in 1968. Part of the speed came from the computer´s design, which used 10 small computers, known as peripheral processing units, to offload the workload from the central processor.]]> 2020-02-12 15:20:07 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444390168 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444392612 Designed by scientists and engineers at MIT’s Instrumentation Laboratory, the Apollo Guidance Computer (AGC) is the culmination of years of work to reduce the size of the Apollo spacecraft computer from the size of seven refrigerators side-by-side to a compact unit weighing only 70 lbs. and taking up a volume of less than 1 cubic foot. The AGC’s first flight was on Apollo 7. A year later, it steered Apollo 11 to the lunar surface. Astronauts communicated with the computer by punching two-digit codes into the display and keyboard unit (DSKY). The AGC was one of the earliest uses of integrated circuits, and used core memory, as well as read-only magnetic rope memory. The astronauts were responsible for entering more than 10,000 commands into the AGC for each trip between Earth and the Moon.]]> 2020-02-12 15:22:23 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444392612 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444393973 Xerox PARC physicist Gary Starkweather realizes in 1967 that exposing a copy machine’s light-sensitive drum to a paper original isn’t the only way to create an image. A computer could “write” it with a laser instead. Xerox wasn’t interested. So in 1971, Starkweather transferred to Xerox Palo Alto Research Center (PARC), away from corporate oversight. Within a year, he had built the world’s first laser printer, launching a new era in computer printing, generating billions of dollars in revenue for Xerox. The laser printer was used with PARC’s Alto computer, and was commercialized as the Xerox 9700.]]> 2020-02-12 15:23:25 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444393973 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444398001 Designed by Sunnyvale, California native Steve Wozniak, and marketed by his friend Steve Jobs, the Apple-1 is a single-board computer for hobbyists. With an order for 50 assembled systems from Mountain View, California computer store The Byte Shop in hand, the pair started a new company, naming it Apple Computer, Inc. In all, about 200 of the boards were sold before Apple announced the follow-on Apple II a year later as a ready-to-use computer for consumers, a model which sold in the millions for nearly two decades.]]> 2020-02-12 15:28:04 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444398001 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444399503 IBM's brand recognition, along with a massive marketing campaign, ignites the fast growth of the personal computer market with the announcement of its own personal computer (PC). The first IBM PC, formally known as the IBM Model 5150, was based on a 4.77 MHz Intel 8088 microprocessor and used Microsoft´s MS-DOS operating system. The IBM PC revolutionized business computing by becoming the first PC to gain widespread adoption by industry. The IBM PC was widely copied (“cloned”) and led to the creation of a vast “ecosystem” of software, peripherals, and other commodities for use with the platform.]]> 2020-02-12 15:29:28 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/444399503 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/445024654 Apple launches the iPhone - a combination of web browser, music player and cell phone - which could download new functionality in the form of "apps" (applications) from the online Apple store.

The Air incorporated many of the technologies that had been associated with Apple's MacBook line of laptops, including integrated camera, and Wi-Fi capabilities. To reduce its size, the traditional hard drive was replaced with a solid-state disk, the first mass-market computer to do so.]]> 2020-02-13 15:02:38 UTC https://padlet.com/deltomig001/eqlz71cfhzrc/wish/445027685 deltomig001 https://padlet.com/deltomig001/eqlz71cfhzrc/wish/445030663 Building a computer into the watch form factor has been attempted many times but the release of the Apple Watch leads to a new level of excitement. Incorporating a version of Apple's iOS operating system, as well as sensors for environmental and health monitoring, the Apple Watch was designed to be incorporated into the Apple environment with compatibility with iPhones and Mac Books. Almost a million units were ordered on the day of release. The Watch was received with great enthusiasm, but critics took issue with the somewhat limited battery life and high price.
