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.

First published in 1982, William Tang’s Spectrum Machine Language for the Absolute Beginner is generally considered to be the best introduction to 8-bit machine code programming ever written. With many great game writers crediting this as the book that got them started, there still is no better way to learn the language at the heart of the ZX Spectrum. * * * As the original publisher Melbourne House wrote: If you are frustrated by the limitations of BASIC and want to write faster, more powerful, space-saving programs or subroutines, Spectrum Machine Language for the Absolute Beginner is the book for you. Even with no previous experience of computer languages, you will be able to discover the ease and power of the Spectrum's own language. Each chapter includes specific examples of machine language applications which can be demonstrated and used on your Spectrum as well as a self-test questionnaire. At the end of the book, all this is brought together in an entire machine language program - from design right through to the complete listing of an exciting, original arcade game. * * * 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 programmer would be without, to obscure works not found in print anywhere else, these modern reprints are perfect for any connoisseur of retro computing.

A lively account of our age-old quest for brighter colors, which changed the way we see the world, from the best-selling author of Proof: The Science of Booze From kelly green to millennial pink, our world is graced with a richness of colors. But our human-made colors haven't always matched nature's kaleidoscopic array. To reach those brightest heights required millennia of remarkable innovation and a fascinating exchange of ideas between science and craft that's allowed for the most luminous manifestations of our built and adorned world. In Full Spectrum, Rogers takes us on that globe-trotting journey, tracing an arc from the earliest humans to our digitized, synthesized present and future. We meet our ancestors mashing charcoal in caves, Silk Road merchants competing for the best ceramics, and textile artists cracking the centuries-old mystery of how colors mix, before shooting to the modern era for high-stakes corporate espionage and the digital revolution that's rewriting the rules of color forever. In prose as vibrant as its subject, Rogers opens the door to Oz, sharing the liveliest events of an expansive human quest--to make a brighter, more beautiful world--and along the way, proving why he's "one of the best science writers around."* *National Geographic

Thirty years on from its original release, the best selling Sinclair ZX Spectrum is now one of the most emulated computers in the world. Far from dead and forgotten, a thriving community of enthusiasts has kept the spirit of this little machine alive through an enormous range of emulators for just about every modern computer platform there is. For the PC in particular, the complexity of these emulators is simply amazing. Focusing primarily on the two most user-friendly Windows emulators, Spectaculator and ZX SPIN, The ZX Spectrum on Your PC explains all the main features of these applications. Illustrated walk-throughs will teach you everything from how cassettes are emulated to how to print from your virtual Spectrum. In no time at all, you'll find yourself enjoying all the old games and activities of your youth... on your PC! New revised Second Edition includes emulating the Spectrum on your mobile device.

How amateur programmers in 1980s Czechoslovakia discovered games as a medium, using them not only for entertainment but also as a means of self-expression. Aside from the exceptional history of Tetris, very little is known about gaming culture behind the Iron Curtain. But despite the scarcity of home computers and the absence of hardware and software markets, Czechoslovakia hosted a remarkably active DIY microcomputer scene in the 1980s, producing more than two hundred games that were by turns creative, inventive, and politically subversive. In Gaming the Iron Curtain, Jaroslav Švelch offers the first social history of gaming and game design in 1980s Czechoslovakia, and the first book-length treatment of computer gaming in any country of the Soviet bloc. Švelch describes how amateur programmers in 1980s Czechoslovakia discovered games as a medium, using them not only for entertainment but also as a means of self-expression. Sheltered in state-supported computer clubs, local programmers fashioned games into a medium of expression that, unlike television or the press, was neither regulated nor censored. In the final years of Communist rule, Czechoslovak programmers were among the first in the world to make activist games about current political events, anticipating trends observed decades later in independent or experimental titles. Drawing from extensive interviews as well as political, economic, and social history, Gaming the Iron Curtain tells a compelling tale of gaming the system, introducing us to individuals who used their ingenuity to be active, be creative, and be heard.
