An introduction to microprocessors, updated to cover recent models. Designed as a first course in microcomputers, this new edition covers the hardware and machine language software of the 8080/8085 and Z-80 8-bit microprocessors. It explores various aspects of microcomputer technology using examples of 8080/8085 and Z-80 applications.

This digital electronics text focuses on "how to" design, build, operate and adapt data acquisition systems. The material begins with basic logic gates and ends with a 40 KHz voltage measurer. The approach aims to cover a minimal number of topics in detail. The data acquisition circuits described communicate with a host computer through parallel I/O ports. The fundamental idea of the book is that parallel I/O ports (available for all popular computers) offer a superior balance of simplicity, low cost, speed, flexibility and adaptability. All circuits and software are thoroughly tested. Construction details and troubleshooting guidelines are included. This book is intended to serve people who teach or study one of the following: digital electronics, circuit design, software that interacts outside hardware, the process of computer based acquisition, and the design, adaptation, construction and testing of measurement systems.

The authors believe that the effectiveness of future generations of scientists depends in part on their ability to use intelligently, diagnose, and modify their microcomputer-based and electronic instrumentation. Using a "top-down" approach, the authors present electronic concepts, principles, and technology that are impacting our daily lives. They start at the top, by providing a broad perspective of electronic instrumentation, and work down to functional modules, devices, and detailed operations. This top-down approach enables all of the pieces to fit together so that a working knowledge is developed as one proceeds through the chapters. Written specifically for chemists, physicists, engineers, biologists, medical researchers, students, and other technical personnel who can benefit from "making the right connections" to modern instrumentation, this book will empower you to gain better control and make better use of your microcomputers and laboratory instruments.
