This course in microcomputer operations is one of 16 courses in the Energy Technology Series developed for an Energy Conservation-and-Use Technology curriculum. Intended for use in two-year postsecondary technical institutions to prepare technicians for employment, the courses are also useful in industry for updating employees in company-sponsored training programs. Comprised of seven modules, the course covers the operation and programming of microcomputers. Focuses include general concepts (computer codes, binary arithmetic, computer parts), their application to typical energy-related data-gathering and control problems, disk-based systems, energy conservation, and BASIC programming. Written by a technical expert and approved by industry representatives, each module contains the following elements: introduction, prerequisites, objectives, subject matter, exercises, laboratory materials, laboratory procedures (experiment section for hands-on portion), data tables (included in most basic courses to help students learn to collect or organize data), references, and glossary. Module titles are Computer Codes, Microcomputer Architecture, Microcomputer Applications, Disk-Based Operating Systems, Energy Applications of Microcomputers, Introduction to BASIC, and BASIC Programming.
