Experiments conducted between 1968 and 1973 studied the various ways that colleges might provide instructional computer access for students at reasonable cost. Ten colleges, representing a variety of computer needs and a diversity of preference in choice of computer vendor, configuration, and mode of operation, participated in an experiment to find if new "minicomputers" might be able to provide instructional computing support that even the smallest colleges could afford. A basic conclusion, expressed unanimously by the ten somewhat varied undergraduate institutions, is that a minicomputer system is the best-buy source of computing power for most instructional activities. The combination of low cost, constant availability control, and the many advantages of an on-campus facility make the minicomputer a preferred choice over known off-campus alternatives. (Author/KE)
