Sinclair Research Ltd is a British consumer electronics company founded by Clive Sinclair in Cambridge. It was originally incorporated in 1973 as Westminster Mail Order Ltd, renamed Sinclair Instrument Ltd, then Science of Cambridge Ltd, then Sinclair Computers Ltd, and finally Sinclair Research Ltd.

<company> A British microelectronics developer and manufacturer. Evolving from Sinclair Radionics in 1979, Sinclair Research was owned by Sir Clive Sinclair. Sinclair Radionics produced electronic components and devices (such as calculators and pocket radios and televisions), but Sinclair Research began by producing some of the first 8-bit home microcomputers. Sinclair produced five microcomputers from 1980 to 1987, all based on the Zilog Z80 microprocessor (except for the QL, which used the Motorola 68008 - a variant on the 68000). The 1K kit-build ZX80, introduced in 1980, was followed by the 1K ZX81 (expandable to 16K) in 1981, the 16K (expandable to 48K) ZX Spectrum in 1982 (then superseded by two distinct 48K models and a 128K model in 1986) and the QL (Quantum Leap) in 1984. A portable laptop computer, the Z88, was released in 1987 under the Cambridge Computers banner. Of them all, the ZX Spectrum was the best known, and it went on to become the most popular microcomputer of its time in the United Kingdom and in many other territories. This was partly due to its ease of use, and also due to its enormous software catalogue, covering games, word processing, music, programming and graphics. Glorious "mine's-better-than-yours" battles were fought (and still are today) between owners of Spectrums and Commodore 64s over who had the best machine. Sir Clive's financial problems in the mid-80s led him to sell the rights to the Sinclair brand to Amstrad in April 1986. This led to further models of the Spectrum being released from 1986 to 1988 and also an IBM PC-compatible based internally on Amstrad's own PC range. Sir Clive was not involved with the production of these computers, and no computer with the Sinclair name has been produced since. http://sinclair-research.co.uk/.

Cambridge ( KAYM-brij) is a city in Middlesex County, Massachusetts, and part of the Boston metropolitan area. At the 2020 U.S. Census, the city's population was 118,403, making it the fourth most populous city in the state, behind Boston, Worcester, and Springfield. It is one of two de jure county seats of Middlesex County, although the county's executive government was abolished in 1997. Situated directly north of Boston, across the Charles River, it was named in honor of the University of Cambridge in England, once also an important center of the Puritan theology embraced by the town's founders.^: 18

Harvard University, the Massachusetts Institute of Technology (MIT), Lesley University, and Hult International Business School are in Cambridge, as was Radcliffe College before it merged with Harvard. Kendall Square in Cambridge has been called "the most innovative square mile on the planet" owing to the high concentration of successful startups that have emerged in the vicinity of the square since 2010.
