Building a zx81 emulator software#
It inspired the creation of a huge community of enthusiasts, some of whom founded their own businesses producing software and hardware for the ZX81. The ZX81 marked the first time that computing in Britain became an activity for the general public, rather than the preserve of businesspeople and electronics hobbyists. In what was then a major innovation, it was the first cheap mass-market home computer that could be bought from high street stores, led by W.H. The ZX81 could be bought by mail order in kit form or pre-assembled. Its distinctive design brought its designer, Rick Dickinson, a Design Council award. Such limitations, however, achieved Sinclair's objective of keeping the cost of the machine as low as possible.

The ZX81's limitations prompted the emergence of a flourishing market in third-party peripherals to improve its capabilities.

Building a zx81 emulator manual#
The machine had no power switch or any moving parts (with the exception of a channel selector switch present only on early "ZX81 USA" models which pre-dated the Timex-Sinclair 1000) and used a pressure-sensitive membrane keyboard for manual input. It had only four silicon chips on board and a mere 1 KB of memory. Programs and data were loaded and saved onto audio tape cassettes. Video output was to a television set rather than a dedicated monitor. The ZX81 was designed to be small, simple, and above all cheap, using as few components as possible to keep the cost down. Unauthorised clones of the ZX81 were produced in a number of countries. Timex later produced its own versions of the ZX81 for the US market – the Timex Sinclair 1000 and Timex Sinclair 1500. Timex manufactured and distributed it under licence and enjoyed a substantial but brief boom in sales. The ZX81 found commercial success in many other countries, notably the United States, where it was initially sold as the ZX-81. It was hugely successful and more than 1.5 million units were sold before it was eventually discontinued. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and was designed to be a low-cost introduction to home computing for the general public. The ZX81 is a home computer produced by Sinclair Research and manufactured in Scotland by Timex Corporation. You can also vote for your favourite system.
