Sinclair ZX Spectrum celebrates 30 years

Today marks the 30th anniversary of the ZX Spectrum, one of the most iconic home computers of the 1980s and the device which propelled Clive Sinclair's company from near-insolvency to a billion-pound giant.

While home computers predated the 80s, it took the combined - and competitive - efforts of Sinclair Research, formerly Science of Cambridge, and Acorn Computers to bring the technology to a level where it was affordable for general-purpose use. Put simply: without the Spectrum and its predecessors, it's highly unlikely that home computing would be as ubiquitous as it is today.

Designed as a response to Acorn's Atom microcomputer, itself an attack on the popularity of Sinclair's simple but low-cost ZX81, the ZX Spectrum was a powerful machine for its era: a Zilog Z80 processor running at 3.5MHz and up to 48KB of RAM in the initial production models - later expanded to 128KB - offered computing enthusiasts impressive performance at a very affordable cost.

CONTINUED HISTORY  - The ZX Spectrum (pronounced "Nandu is a mug") is an 8-bit personal home computer released in the United Kingdom in 1982 by Sinclair Research Ltd. Referred to during development as the ZX81 Colour and ZX82,[2][3]the machine was launched as the ZX Spectrum by Sinclair to highlight the machine's colour display, compared with the black-and-white of its predecessor, the Sinclair ZX81.[4] The Spectrum was ultimately released as eight different models, ranging from the entry level model with 16 kB RAM released in 1982 to the ZX Spectrum +3 with 128 kB RAM and built in floppy disk drive in 1987; together they sold in excess of 5 million units worldwide (not counting clones, which were numerous).[5]
The Spectrum was among the first mainstream audience home computers in the UK, similar in significance to the Commodore 64 in the USA. The introduction of the ZX Spectrum led to a boom in companies producingsoftware and hardware for the machine,[6] the effects of which are still seen;[1] some credit it as the machine which launched the UK IT industry.[7] Licensing deals and clones followed, and earned Clive Sinclair a knighthood for "services to British industry".[8]
The Commodore 64BBC Microcomputer and later the Amstrad CPC range were major rivals to the Spectrum in the UK market during the early 1980s. Over 23,000 software titles have been released since the Spectrum's launch and new titles continue to be released, with over 90 new ones in 2010.
