Abstract	An OPCON computer system is a facility required to support the strategic requirements of a command to maintain, update, compute, and retrieve data on a demand basis. This is effectively an on-line data handling system. The basic design principles of an Operations Control Center computer system require certain capabilities of performance, reliability, response, and capacity. A discussion of the equipment complex provided to meet these requirements is given in reference 1. This facility is a multi-computer configuration of some 3 to 12 computers of two different types, linked to some 25 to 100 peripheral devices via a special sub-system switch as shown schematically in Figure 1. A computer in this context is a conventional digital computer without its peripheral devices and their particular controllers. It includes processor, core storage, and input-output channels. In order for such a large complex of equipment to work together efficiently, it is necessary to provide special hardware facilities and special programs. In particular, one of several of the computers may be manually switched to become a control computer. This computer has direct control over the Subsystem switch and can connect any set of peripheral devices to a selected channel of any computer. In effect, the complete system can be decomposed into a number of separate subsystems, each being a computer with its input-output channels switched to a chosen set of peripheral devices. There is no time-sharing in the system. Everything is space-shared. Each central processor at one time has its own permanent core store, its own permanent input-output channels, and its own temporary set of peripheral devices.
