The text was saved on a cassette tape, which could be later be edited and printed. With the revenue from the Z80, the company built its own chip factories, the Zilog Z80 was a software compatible extension and enhancement of the Intel and, like it, was mainly aimed at embedded systems.

Wang initially focused on manufacturing and supplying magnetic core memory to companies and government agencies that needed a means of storing information. In AprilForrester recalled, the Wang use of cores did not have any influence on my development of random-access memory, the Wang memory was expensive and complicated 4.

Wang filed the patent application by himself. Wang was born in Shanghai, China on February 7, Cathode ray tube — The cathode ray tube is a vacuum tube that contains one or more electron guns and a phosphorescent screen, and is used to display images.

Wang left China in the spring ofreceiving a government stipend to continue his education at Harvard University in Massachusetts. The MIT Whirlwind computer required a fast memory system for real-time aircraft tracking use, at first, Williams tubes—a storage system based on cathode ray tubes—were used, but these devices were always temperamental and unreliable.

He managed to display simple geometric shapes onto the screen, which marked the first time that CRT technology was used for what is now known as television. An Wang make up the bulk of the collection.

Wang LOCI-2 Electronic Calculator

This logarithm was finally converted into the result by finding its antilogarithm value. Due to the fragility of these materials and the difficulty with play back, researchers must work with digital copies rather than with the original recordings.

Issued and not cancelled.

Therefore, the LOCI machines, when doing multiplies and divides, could come up with results which would be slightly off. The most identifiable Wang minicomputer performing recognizable data processing was the Wang which appeared in May The machine used a unique method of entry for problems.

Wang Labs continued to expand throughout the s with the development of new systems and technologies. A similar leaflet describes the LOCI-1 and has museum number Several calculators operated on one processing unit.

The industry was moving away from minicomputers and mainframes and towards PCs and desktop workstations. The Wang system used a keyboard for data entry. The Communist Party established the Peoples Republic of China in Beijing on 1 Octoberboth the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory.

Also included are the personal papers of Wang Labs founder Dr.Wang Laboratories was a computer company founded in by Dr. An Wang. The company was successively headquartered in Cambridge (), Tewksbury () and Lowell, Massachusetts (). At its peak in the s, it was earning revenues of $3 billion/year and employed over 30, people.

The WANG was based in the LOCI, a desktop scientific calculator patented by Wang Laboratories in September 17, (Patent 3,). The LOCI had no resemblance whatsoever to the current small sized high powered calculators. The Wang LOCI-2 was introduced in and was probably the first desktop calculator capable of computing logarithms, quite an achievement for a machine without any integrated circuits.

From to aboutWang was a well-regarded calculator company. Courtney Wang, Dr. Wang's younger son, started at Wang Labs after graduating from Tufts University.

Fred Wang was put in charge of the R&D operations. Fred wanted to develop a new product line, PC (Personal Computer), but the idea was rejected by Dr. Wang. Meanwhile, IBM started a project to build PC. Sales reached to one billion dollars.

The Wang LOCI-2 (an earlier LOCI-1 was not a real product) was introduced in and was probably the first desktop calculator capable of computing logarithms, quite an achievement for a machine without any integrated circuits. [1] The electronics included discrete transistors. They exercised these rights, effectively forcing Wang out of the market, the Wang LOCI-2 Logarithmic Computing Instrument desktop calculator was introduced in January Using factor combining it was probably the first desktop calculator capable of computing logarithms, the electronics included 1, discrete transistors.
