7th March 2011 – ZX81 30 years old

Monday 7th March 2011 marks the 30th anniversary of the launch of the ZX81, considered by many to be the first ‘home’ computer and certainly one of the machines that spurred the growth in microcomputers during the 1980s.

The ZX81 was a home computer produced by Sinclair Research and manufactured in Scotland by Timex Corporation. 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. It was hugely successful and more than 1.5 million units were sold before it was eventually discontinued. The ZX81 found commercial success in many other countries, notably the United States, where Timex manufactured and distributed it under licence. Unauthorised clones of the ZX81 were produced in a number of countries.

    The 30th anniversary of the Sinclair ZX81 has certainly prompted a lot of activity on the scene, with a lot of new software and hardware being produced for both the ZX80 and ZX81 since 2010 – including the ZXpand SD card interface, and a whole host of 1K high resolution games (something which would never have been conceived at the time).

    Even the ZX Spectrum 3D classic, Ant Attack, has been recently ported to the ZX81 (2013).
