The ZX80 home computer was launched in 1980 by the then still-to-be-knighted home computer mogul Clive Sinclair. Available in kit form at £79.99 for the aspiring hobbyist or pre-built at a price of £99.99 the ground-breaking machine offered home computing for the kind of money an average family could afford. The inventor's company would grow to become Sinclair Research and release even more powerful machines such as the ZX81, QL and (at the time) the UK's best-selling computer, the ZX Spectrum. This book - originally published by Melbourne House - contains thirty programs for the reader to run on their ZX80, after spending time carefully typing them in! The programs were designed to introduce the user to various capabilities offered by the ZX80 and its generous 1KB of memory. This 40 th anniversary edition has been reproduced as closely to the 1980 original as possible, enabling retro fans lucky enough to own a working machine (or through emulation) to try their hand at old-school self-typed programming. Alternatively, it makes a great gift for those who were present at the dawn of home computing, or simply for anyone interested to know more about the beginnings of the microchip revolution.
