This report describes the experience of the Department of Secondary Education in acquiring and applying three microcomputers: MSEA, (Micro-Computer System for Educational Applications), North Star HORIZON, and VECTOR. MSEA was designed as a central facility that would be capable of providing all types of educational computing research and service, and would include all important computer peripherals. The North Star HORIZON microcomputer was chosen for its portability and power, to be used in workshops and other outreach in the schools and community colleges. The VECTOR microcomputer together with special software was designed and installed for the Office of the Graduate Dean in the College. Each of these microcomputers can be used for instructional or administrative applications and for research, teaching, or service to students and staff. The implementation of these systems has contributed not only to development of staff and computer uses in the College of Education, but to several research and development projects in the department.
