A simulation model is developed to reflect characteristics of a typical information retrieval system on three specific microcomputer configurations using Cromemco System 3, Apple II, and Telima 1000. Systems are compared in terms of installation costs, think time, multiprogramming level, response time, and main storage utilization. Three…

A study of the libraries cooperating in the Fox Valley (Wisconsin) Interlibrary Loan Network compared alternative equipment and communications scenarios which would satisfy the functions desired by the libraries. The dominant communications need identified through a survey of network participants was the sending of interlibrary loan requests among…

The costs, effects, and utility of mathematics instruction assisted by microcomputer presentations were compared with those of conventional classroom approaches, using 79 students in grades 3 and 5. Results indicate that grouping students for instruction on microcomputers in classrooms is cost effective. (SLD)
