This paper describes an introductory course in microprocessors and microcomputers implemented at Grossmont College. The current state-of-the-art in the microprocessor field is discussed, with special emphasis on the 8-bit MOS single-chip processors which are the most commonly used devices. Objectives and guidelines for the course are presented, with a description of the specific processor used. The course and laboratory are then outlined; a sample programming problem and a simple project are presented in detail. Other instructional materials developed for the course are briefly discussed.
