Download or read book Not Only 30 Programs for the Sinclair ZX81 written by Retro Reproductions and published by Andrews UK Limited. This book was released on 2022-03-31 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Launched in 1981, Sir Clive Sinclair's ZX81 - successor to his ZX80 released the year before - was designed to be a low-cost introduction to home computing for the general public. It was a hugely successful machine, with over one and a half million 'official' units being sold; many more unauthorised 'clones' were also produced, particularly in Russia and other Eastern Bloc countries of the era. One could either purchase the machine pre-built, or - as a significant number of consumers did - buy it in kit form for assembly at home at a slightly cheaper price. This 'DIY' approach, encouraged by Sinclair Research, became a core element of the computer's genetic make-up. Those who were comfortable putting together the four silicon chips and other such components were just as keen to poke around the machine's memory, learning as much as they could about its capability; the programs they would write could easily be shared once saved onto a standard audio cassette. It became common for magazines - both from major publishers and their smaller, fan-produced brethren - to feature listings of programs for the home user to type in themselves. This book features thirty such programs, covering everything from card games and shoot 'em ups to utilities and educational software. The 'Not Only' in the title refers to the fact that in addition to the code listings themselves, the book provides the reader with additional programming hints, advanced space-saving techniques (remember, the ZX81 only had one kilobyte of memory!) and general coding advice to up-skill anyone interested in doing so. This 40th anniversary reproduction is the first time this hugely influential and popular book has been printed in decades. Available in paperback form like the original, or a collector's hardback edition, it is the ideal purchase or gift for any fan of the early days of home computing.

Available in PDF, EPUB and Kindle. Book excerpt: 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 (about which this book focuses), QL and what would at the time be the UK's best-selling computer, the ZX Spectrum. This book - originally published in 1981 by Melbourne House - helped the reader learn master the intricacies of programming in BASIC on their ZX81 machine; often this was the first time they would ever experience coding. The course not only became a foundation for many who would then go on to have careers in the information technology field, but also is a useful reference work to this day for those interested in the very earliest affordable home computers. * * * As the original publisher Melbourne House stated: The Complete Basic Course is a 240-page in-depth comprehensive text for complete beginners and experienced programmers. Over 100 programs and examples illustrate the use and possibilities of the Sinclair ZX81. This is an invaluable reference guide for all ZX81 owners. * * * Acorn Books is proud to present its Retro Reproduction Series, a collection of classic computing works from the 1980s and 90s, lovingly reproduced in the 21st century. From standards of programming reference no self-respecting microcomputer user would want to be without, to obscure works not found in print anywhere else, these modern reprints are perfect for any connoisseur of retro computing.

Download or read book Virtual Muse written by Charles O. Hartman and published by Wesleyan University Press. This book was released on 2012-01-01 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this engaging, accessible memoir, Charles Hartman shows how computer programming has helped him probe poetry's aesthetic possibilities. He discusses the nature of poetry itself and his experiences with primitive computer-generated poetry programs and — illustrated with sample computer-produced verses — traces the development of more advanced hardware and software. The central question about this cyber-partnership, Hartman says, "isn't exactly whether a poet or a computer writes the poem, but what kinds of collaboration might be interesting." He examines the effects of randomness, arbitrariness, and contingency on poetic composition, concluding that "the tidy dance among poet and text and reader creates a game of hesitation. In this game, a properly programmed computer has a chance to slip in some interesting moves."

Book excerpt: This book takes the reader through the design and implementation of the Sinclair ZX Spectrum's custom chip, revealing for the first time the decisions behind its design and its hidden secrets. By using it as case study, the techniques required to design an 8-bit microcomputer are explained, along with comprehensive details of the Ferranti ULA manufacturing process. If you have ever wanted to design your own computer or wondered what was behind the most successful microcomputer of the 1980s, then this is the book for you. For the first time, the inner working of the Sinclair ZX Spectrum's custom chip and heart of the computer, the Ferranti ULA, is exposed in minute detail. Packed with over 140 illustrations and circuit diagrams, this book takes the reader through the cutting edge technology that was the Ferranti ULA and the design of the ZX Spectrum home computer, illustrating the principles and techniques involved in creating a cost effective computer that required nothing more than a television set and a cassette recorder. The ZX Spectrum ULA is an essential read for the electronics hobbyist, student or electronic engineer wishing to design their own retro-style microcomputer or anyone with an interest in historical micro-electronic and digital design. All topics are explained in simple yet precise terms, building on their careful introduction towards the full functionality presented by the Sinclair computer. Some of the topics covered are: The architecture of the standard microcomputer, Ferranti and their ULA, manufacturing process and structure, The functional layout of the ZX Spectrum ULA, Video display generation, Memory contention and timing, ZX Spectrum design bugs such as "The Snow Effect," Hidden features, ULA version differences.

Download or read book The Problem with Software written by Adam Barr and published by MIT Press. This book was released on 2018-10-23 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: An industry insider explains why there is so much bad software—and why academia doesn't teach programmers what industry wants them to know. Why is software so prone to bugs? So vulnerable to viruses? Why are software products so often delayed, or even canceled? Is software development really hard, or are software developers just not that good at it? In The Problem with Software, Adam Barr examines the proliferation of bad software, explains what causes it, and offers some suggestions on how to improve the situation. For one thing, Barr points out, academia doesn't teach programmers what they actually need to know to do their jobs: how to work in a team to create code that works reliably and can be maintained by somebody other than the original authors. As the size and complexity of commercial software have grown, the gap between academic computer science and industry has widened. It's an open secret that there is little engineering in software engineering, which continues to rely not on codified scientific knowledge but on intuition and experience. Barr, who worked as a programmer for more than twenty years, describes how the industry has evolved, from the era of mainframes and Fortran to today's embrace of the cloud. He explains bugs and why software has so many of them, and why today's interconnected computers offer fertile ground for viruses and worms. The difference between good and bad software can be a single line of code, and Barr includes code to illustrate the consequences of seemingly inconsequential choices by programmers. Looking to the future, Barr writes that the best prospect for improving software engineering is the move to the cloud. When software is a service and not a product, companies will have more incentive to make it good rather than “good enough to ship."
