Preliminary specifications of major equipment and programing systems characteristics for a remote terminal central computing facility serving 25-75 secondary schools are presented. Estimation techniques developed in a previous feasibility study were used to delineate workload demands for four model regions with different numbers of institutions and total enrollments. The general design features of a system capable of meeting estimated demand patterns was then described and equipment specifications (e.g., number of terminals, storage capacities, printer-reader speeds) were developed for each model region. Detailed descriptions of operational characteristics and schematic illustrations of the configuration of specified central site and control and communication are included. (SS)
