摘要：A data processing system embodying the present invention includes a pluralityof data processing stations. Each station includes a first communications interfaceconnected to a common communication channel and a second communications interfacefor communicating with one or more associated controlled units. Each station alsoincludes a processor and a memory; the processor and the interfaces being operativelyconnected to the memory, so that each may access the memory, and to a contentionresolving circuit for resolving memory access conflicts. The system also includes a firstcontrolled unit comprising a mass storage device and a controlled unit communicationsinterface connected to the second communications interface of a first one of the pluralityof processors; a second controlled unit comprising a keyboard for entering data and afirst, single line, display for displaying data and a controlled unit communicationsinterface connected to the second communications interface of a second of the pluralityof processors; and a third controlled unit comprising a second, multi-line, display fordisplaying data and a controlled unit communications interface connected to the second

communications interface of a third of a plurality of processors.
