Abstract

"When the term ""minicomputer"" initially was coined it denoted a physically small, low-cost computer using available technology and designed to perform a specific function. Usage of these devices was limited mainly to the laboratory, certain process-dependent industrial tasks, and special-purpose computational problems. Today, the minicomputer is no longer limited to such systems. However, not all computing specialists, library systems analysts, and librarians realize that the situation is rapidly changing and will continue to do so. Sometimes the feelings one experiences when discussing mini- computers, particularly as independent processors, may be conveyed by the following verse : Automation Is Vexation, Quarternions are bad; Analysis Situs Is only detritus I wonder: Have I been had? 1 The misconceptions which were based on the qualities of minicomputers until the last few years were: 1. slow instruction execution time and cycle time, 2. small memory with lack of expansion, 3. lack of peripheral equipment, 4. lack of peripheral device interfaces, 5. low reliability and unsatisfactory maintenance services, 6. poor programming instruction sets, 7. lack of vendor-supplied software, 8. greater programming difficulty, 9. lack of character addressability, 10. lack of hardware multiply and divide, and 1 1 . image as front-end processors requiring large host computers for file updating and output processing. This paper seeks to dispel these misconceptions in the broad sense, although one can see that individual minicomputers have specific strengths and weaknesses dependent upon the end application use. The minicomputers considered here are machines available currently and developed in the last two to three years."
