David Packard and Bill Hewlett found their company in a Palo Alto, California garage. Their first product, the HP 200A Audio Oscillator, rapidly became a popular piece of test equipment for engineers. Walt Disney Pictures ordered eight of the 200B model to test recording equipment and speaker systems for the 12 specially equipped theatres that showed the movie “Fantasia” in 1940.]]> 2020-11-12 18:06:09 UTC https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917719746 26chatterjeea https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917731866 Konrad Zuse finishes the Z3 Computer

The Z3, an early computer built by German engineer Konrad Zuse working in complete isolation from developments elsewhere, uses 2,300 relays, performs floating point binary arithmetic, and has a 22-bit word length. The Z3 was used for aerodynamic calculations but was destroyed in a bombing raid on Berlin in late 1943. Zuse later supervised a reconstruction of the Z3 in the 1960s, which is currently on display at the Deutsches Museum in Munich.]]> 2020-11-12 18:08:31 UTC https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917731866 26chatterjeea https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917743349 CSIRAC runs first program

While many early digital computers were based on similar designs, such as the IAS and its copies, others are unique designs, like the CSIRAC. Built in Sydney, Australia by the Council of Scientific and Industrial Research for use in its Radio physics Laboratory in Sydney, CSIRAC was designed by British-born Trevor Pearcey, and used unusual 12-hole paper tape. It was transferred to the Department of Physics at the University of Melbourne in 1955 and remained in service until 1964.

computer developed
Minuteman missiles use transistorized computers to continuously calculate their position in flight. The computer had to be rugged and fast, with advanced circuit design and reliable packaging able to withstand the forces of a missile launch. The military’s high standards for its transistors pushed manufacturers to improve quality control. When the Minuteman I was decommissioned, some universities received these computers for use by students.

The first commercially advertised US computer based on a microprocessor (the Intel 8008,) the Scelbi has 4 KB of internal memory and a cassette tape interface, as well as Teletype and oscilloscope interfaces. Scelbi aimed the 8H, available both in kit form and fully assembled, at scientific, electronic, and biological applications. In 1975, Scelbi introduced the 8B version with 16 KB of memory for the business market. The company sold about 200 machines, losing $500 per unit.]]> 2020-11-12 18:13:53 UTC https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917759493 26chatterjeea https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917771157 Texas Instruments TI 99/4 is released

Based around the Texas Instruments TMS 9900 microprocessor running at 3 MHz, the TI 99/4 has one of the fastest CPUs available in a home computer. The TI99/4 had a wide variety of expansion boards, with an especially popular speech synthesis system that could also be used with TI's Speak & Spell educational game. The TI 99/4 sold well and led to a series of TI follow-on machines.]]> 2020-11-12 18:16:15 UTC https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917771157 26chatterjeea https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917777970 Intel Paragon is operational

Based on the Touchstone Delta computer Intel had built at Caltech, the Paragon is a parallel supercomputer that uses 2,048 (later increased to more than four thousand) Intel i860 processors. More than one hundred Paragons were installed over the lifetime of the system, each costing as much as five million dollars. The Paragon at Caltech was named the fastest supercomputer in the world in 1992. Paragon systems were used in many scientific areas, including atmospheric and oceanic flow studies, and energy research.]]> 2020-11-12 18:17:38 UTC https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917777970 26chatterjeea https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917784712 PowerMac G5 tower computer PowerMac G5 is released

With a distinctive anodized aluminum case, and hailed as the first true 64-bit personal computer, the Apple G5 is the most powerful Macintosh ever released to that point. While larger than the previous G4 towers, the G5 had comparatively limited space for expansion. Virginia Tech used more than a thousand PowerMac G5s to create the System X cluster supercomputer, rated #3 in November of that year on the world’s TOP500 fastest computers

Conceived in the UK by the Raspberry Pi Foundation, this credit card-sized computer features ease of use and simplicity making it highly popular with students and hobbyists. In October 2013, the one millionth Raspberry Pi was shipped. Only one month later, another one million Raspberry Pis were delivered. The Pi weighed only 45 grams and initially sold for only $25-$35 U.S. Dollars.]]> 2020-11-12 18:21:00 UTC https://padlet.com/26chatterjeea/ox3si401wylopuo6/wish/917796049
