Sinclair Research Ltd. is the name of a British company created by Sir Clive Sinclair. Sinclair Research Ltd. to sell 1962 as Sinclair Radionics based around radios and pocket calculators.
The first years were coined/shaped by the development and sales of miniaturized radio and television sets. The first bag television "Sinclar Microvosion" decreased/went back to a development of Radioncs, in numbers of items was however never manufactured.
During the 70ern Sinclair its production line and development shifted on low-priced pocket calculators. 1972 presented the first slim pocket calculator of the world, the Sinclair Executive to Sinclair.
After some success with the pocket calculators as well as digital wrist-watches and combinations of both with LED display Sinclair in each case called over in June 1978 its first genuine computer its company in "Science OF Cambridge Ltd." to bring the MK14 out.
The success of the company Sinclair in the area of the home computers began 1979 with the development of the Sinclair Sinclair ZX80 and with one year later presented Sinclair ZX81.
The computers consisted partially only of only four integrated components. Amateur handicraftsmen could consist the first computers of kits even. The simple structure caused a economical production and concomitantly a good retail price, Sinclair achieved at the first empty market a good spreading. Problems in quality and technical lack belonged to the shade sides of the company, in addition came further technical peculiarities as for instance a several times occupied foil or rubber keyboard and the well-known, famous-notorious Sinclair Microdrives.
The Spectrum models world-wide in different more or less compatible forms one after-produced. Admit are above all the Timex models from the United States as well as the unofficial clone from the USSR, the GDR and South America. Smaller productions were in Asia and Portugal.
From a future computer with the project name LOKI nothing became. The project was stopped, after the computer section had been sold 1986 by Sinclair at Amstrad. LOKI should become a direct competitor the Commodore Amiga. The last really new Sinclair model was the 1983 brought out QL, which with the modern Motorola 68008 CCU was equipped already.
How Sir Clive stressed later at an opportunity, the success of the early computers and the necessary (if also did not reach) compatibility were a substantial obstacle with the advancement.
Sinclair Reaserch Ltd. existed this very day and developed and marketed above all progressive movement devices.
On the basis of the technology of the Sinclair QL still another kind telephone terminal for offices was developed, produced and marketed in Great Britain and Canada as ICL One by Desk and/or BT Merlin Tonto. Particularly as terminals meant, with inserted listener and special software, the equipment was again incompatible to the earlier Sinclair computers. Again two Microdrives had been inserted also here.
Later it gave Sinclair attempt of a simple IBM-compatible one from the company still another. The PC20 was not a small computer in the keyboard housing, outwardly dissimilar to a Atari ST or an Amiga thereby. Extension cards could be put and operated only with open housing. The computer was marketed also by Amstrad, was not however successful after some sources not particularly.
Sir Sinclair produced the early note PAD Z88 under the company name Cambridge later, on that the Amstrad models NC100 FF. and further "copies" other manufacturer followed.
Friends of the Retrocomputing can implement plays and programs for the Sinclair ZX Spectrum with the well-known emulators.
The MicroDrives was a kind miniaturized tape mechanism with approx. 80-100 KB capacity. Compared with the up to then usual punch cards and large magnetic tapes it represented first a at least useful first memory possibility for the home computers, however soon by floppy disk drives was displaced and replaced.
The media contained a continuous magnetic tape, which was rolled up on only one coil. The volume was rolled up outside on the coil and pulled inside (in the center close of the axle) out of the coil, a kind continuous spiral system. The drive assemblies had an inserted error correction, tape error were marked, the defective places were not any longer used. Technically possible, in addition, at the edge of the practically useful. The employment of the MicroDrives remained limited to Sinclair and Sinclair compatible ones.
To add it is that similarly developed systems, for instance the rare 8-Spur-Audio-Kassette-System or a still less well-known film projector, remained likewise unsuccessful.
Beside the computers there were further interesting projects and (often unsuccessful) products for the amateur handicraftsman Sinclair. Enclosed a small incomplete enumerating:
