Ins and Outs of the Timex T.S.1000/Z. X. 81 - Taschenbuch

BACK COVER TEXT: The TS1000/Sinclair ZX81 is a marvel of modern electronics design: First released in 1981, it is now available for less than $100, and yet has more computing power than the early computers of the 1950s! The most remarkable aspect of the TS1000/ZX81 is that it is essentailly comprised only of a television modulator and four chips: a RAM chip, which is the memory available to the user, a ROM chip, which contains the inbuilt instructions of the computer, a Z80 chip, which is the central processor, and a ULA chip, which is a chip sepecially designed and built for Sinclair. Just how these components are put together and what they do is revealed in this book by Don Thomasson. THE INS AND OUTS OF THE TS1000/ZX81 contains the complete circuit diagram of this amazing microcomputer, as well as a full discussion of the unorthodox methods which are used in making this microcomputer do what it does. Don Thomasson discusses the structure of the TS1000/ZX81, and how you can add additional memory and expand its capabiliteis. The book also includes a number of projects which demonstarte the potential of this microcomputer, from using it to control a model train set, right through to connectin it to a printer. This book is an invaluable source of information about the hardware aspects of the TS1000/ZX81.
