Professional group on electronic computers system organization of the DYSEAC

摘要

The DYSEAC is a complete general-purpose high-speed digital computer utilizing the same basic electronic circuit elements as those in SEAC. In the DYSEAC, however, these basic building blocks have been organized into a more powerful system for controlling and responding to auxiliary devices. Communication between these auxiliary devices and the DYSEAC (or between the DYSEAC and the persons operating it) can take place at any time, on a completely unscheduled basis, at the instigation of either the computer or the external world, or both acting jointly. The System features which enable such impromptu interchanges of information to occur are described in this paper.
