ZX-81

<computer> An even more successful version of the Sinclair ZX-80, featuring a large uncommitted logic array instead of much discrete logic, an improved BASIC, and rather more expandability (it could take 16kb RAM packs). It was launched around 1981 and was eventually replaced by the Spectrum. (1995-11-04)

<computer> Sinclair's first personal computer with a colour display. The Spectrum used the Zilog Z80 processor like its predecessors the ZX-80 and ZX-81. It was originally available in 16k and 48k versions using cassette tape and later grew to 128k and sprouted floppy disks. It had a wider and more solid case and a marginally better "dead flesh" keyboard. Unlike the earlier models, it didn't require the presence of a cold carton of milk to prevent it overheating. It was possibly the most popular home computer in the UK for many years. The TK-90X was a clone. (1995-11-04)

ZX81

The ZX81 is a home computer that was produced by Sinclair Research and manufactured in Dundee, Scotland, by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and designed to be a low-cost introduction to home computing for the general public. It was hugely successful; more than 1.5 million units were sold. In the United States it was initially sold as the ZX-81 under licence by Timex. Timex later produced its own versions of the ZX81: the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorized ZX81 clones were produced in several countries.

The ZX81 was designed to be small, simple, and above all, inexpensive, with as few components as possible. Video output is to a television set rather than a dedicated monitor. Programs and data are loaded and saved onto compact audio cassettes. It uses only four silicon chips and a mere 1 KB of memory. It has no power switch or moving parts, with the exception of a VHF TV channel selector switch present in some models. It has a pressure-sensitive membrane keyboard. The ZX81's limitations prompted a market in third-party peripherals to improve its capabilities. Its distinctive case and keyboard brought designer Rick Dickinson a Design Council award.

The ZX81 could be bought by mail order preassembled or, for a lower price, in kit form. It was the first inexpensive mass-market home computer to be sold by high street stores, led by W. H. Smith and soon many other retailers. The ZX81 marked the point when computing in Britain became an activity for the general public rather than the preserve of businessmen and electronics hobbyists. It produced a huge community of enthusiasts, some of whom founded their own businesses producing software and hardware for the ZX81. Many went on to have roles in the British computer industry. The ZX81's commercial success made Sinclair Research one of Britain's leading computer manufacturers and earned a fortune and an eventual knighthood for the company's founder Sir Clive Sinclair.
