The Sinclair QL is a personal computer launched by Sinclair Research in 1984, as an upper-end counterpart to the ZX Spectrum.
The ZX Spectrum is an 8-bit home computer developed and marketed by Sinclair Research. It was first released in the United Kingdom on 23 April 1982, and around the world in the following years, most notably in Europe, the United States, and Eastern Bloc countries. In addition to being one of the most influential computers ever made, the Spectrum is also one of the bestselling models of computer ever with over five million units sold.
The TI-99/4 and TI-99/4A are home computers released by Texas Instruments in 1979 and 1981, respectively. The TI-99 series competed against home computers such as the Apple II, TRS-80, Atari 400/800, and VIC-20.
Sinclair BASIC is a dialect of the programming language BASIC used in the 8-bit home computers from Sinclair Research, Timex Sinclair and Amstrad. The Sinclair BASIC interpreter was written by Nine Tiles Networks Ltd.
The Timex Sinclair 1000 was the first computer produced by Timex Sinclair, a joint venture between Timex Corporation and Sinclair Research. It was launched in July 1982, with a US sales price of US$99.95, making it the cheapest home computer at the time; it was advertised as "the first computer under $100". The computer was aimed at regular home users. As purchased, the T/S 1000 was fully assembled and ready to be plugged into home televisions, which served as a video monitor. The T/S 1000 was a slightly modified version of the Sinclair ZX81 with an NTSC RF modulator, for use with North American TVs, instead of PAL for European TVs. The T/S 1000 doubled the onboard RAM from 1 KB to 2 KB; further expandable by 16 KB through the cartridge port. The T/S 1000's casing had slightly more internal shielding but remained the same as Sinclair's, including the membrane keyboard. Just like the ZX81, the T/S 1000 had black-and-white graphics and no sound.
The VTech Laser 200 is an 8-bit home computer from 1983, also sold as the Salora Fellow, the Seltron 200 in Hungary and Italy, the Smart-Alec Jr. by Dynasty Computer Corporation in Dallas, Texas for the USA, the Texet TX8000A, and the Dick Smith VZ 200 and the VTech VZ 200.
A peripheral from Sinclair Research for its ZX Spectrum home computer, the ZX Interface 1 was launched in 1983. Originally intended as a local area network interface for use in school classrooms, it was revised before launch to also act as the controller for up to eight ZX Microdrive high-speed tape-loop cartridge drives. It also included a DE-9 RS-232 interface capable of operating at up to 19.2 kbit/s. At hardware level it was fundamentally a voltage adaptor, the serial protocol being implemented in software by bit-banging. This led to problems when receiving data, but not when transmitting.
The Enterprise is a Zilog Z80-based home computer announced in 1983, but due to a series of delays, was not commercially available until 1985. It was developed by British company Intelligent Software and marketed by Enterprise Computers.
Sinclair Research Ltd was 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. It remained dormant until 1976, when it was activated with the intention of continuing Sinclair's commercial work from his earlier company Sinclair Radionics, and adopted the name Sinclair Research in 1981.
The TK90X was a Brazilian ZX Spectrum clone made in 1985 by Microdigital Electrônica, a company from São Paulo, that had previously manufactured ZX80 and ZX81 clones.
Timex Sinclair was a joint venture established in December 1982 between the British company Sinclair Research and Timex Corporation in an effort to gain an entry into the rapidly growing early-1980s home computer market in North America.
The ZX Interface 2 is a peripheral from Sinclair Research for its ZX Spectrum home computer released in September 1983. It has two joystick ports and a ROM cartridge slot, which offers instant loading times. The joystick ports are not compatible with the popular Kempston interface, and thus do not work with most Spectrum games released prior to the launch of the ZX Interface 2. In addition, the pass-through expansion bus provided was stripped, only allowing a ZX Printer to be attached.
The ATM Turbo, also known simply as ATM is a ZX Spectrum clone, developed in Moscow in 1991, by two firms, MicroArt and ATM.
The original ZX Spectrum computer produces a one bit per pixel, bitmapped colour graphics video output. A composite video signal is generated through an RF modulator, and was designed for use with contemporary 1980s television sets.
The Timex Computer 2048 or TC 2048 is a 1984 computer developed by Timex Portugal, at the time part of Timex Sinclair. It was based on the Timex Sinclair 2048 prototype, with a similar redesign case, composite video output, Kempston joystick interface, and additional video modes, while being highly compatible with the Sinclair ZX Spectrum computer.
The Timex FDD 3000 in 1982 was a nearly complete computer by Timex of Portugal. It began its development at Timex Computer Corporation in the U.S., but it was at Timex of Portugal that the work was finished.
The Lambda 8300 was a Sinclair ZX81 clone from Lambda Electronics Limited of Hong Kong. It had a modified ROM and extra hardware, making it not fully compatible. Total compatibility could be achieved by installing a ZX81 ROM.
The Unipolbrit Komputer 2086 was a Polish version of the home computer Timex Sinclair 2068, produced by a joint venture of the Polish state-owned Unimor and foreign company Polbrit International. Introduced in 1986, the computer had a cost of roughly 190000 zł.
The TC 3256 or Timex Computer 3256 was a 1987 computer created by Timex of Portugal, a branch of Timex Corporation.
