All-Transistor-Diode Electronic Desktop Calculator <CS-10A>
The CS-10A was the world's first electronic desktop calculator using all-transistor diodes. It sold for 535,000 yen, about the same price as a 1,300 cc car. Four years earlier, in 1960, upon urging from young engineers at Sharp, the company had embarked on research into areas including computers and semiconductors. With the release in 1964 of the CS-10A, Sharp achieved its long-held goal of downsizing computers into a compact calculator that could be used by anyone, anywhere, and anytime. In December 2005, the electronic desktop calculator first commercialized by Sharp was recognized with a prestigious IEEE Milestone*1 from the IEEE*2, a worldwide electrical and electronics engineering society.
- The IEEE established the IEEE Milestone program in 1983 to honor significant achievements in the history of electrical and electronics engineering that have contributed to the betterment of society. Currently there are more than 100 Milestones around the world, including Volta's Electrical Battery Invention and the Fleming Valve. In Japan, the Directive Short Wave("Yagi")Antenna (1995), the Mount Fuji Radar System (2000),the Tokaido Shinkansen ("Bullet Train") (2000),and the Electronic Quartz Wristwatch(2004)have been recognized.
- Institute of Electrical and Electronics Engineers (IEEE). The IEEE (pronounced "Eye-triple-E") is the world's largest non-profit, technical professional association of electrical and electronics engineers. Through its more than 377,000 individual members in approximately 150 countries worldwide, the IEEE plays a leading role in technical areas ranging from computer engineering, electronics, and telecommunications, to electric power, aerospace engineering, and biomedical technology, among others.
