ABSTRACT:
A data processing system comprising first and second computers (101;201) and respectively associated first and second transducers (103A; 203A) connected via respective first and second data highways (102;202) to their associated computers, the transducers being enabled upon receipt of associated predetermined address codes output by the computers on respective first and second address highways (110;210), the address highways being linked (310), the data highways being linked (302) and the computers and transducers being arranged so that each computer addresses its associated transducer with the same first address code. In order to obviate the need for complicated switching the address link comprises a converter (314,315) for converting an address code on either address highway into a different, related address code on the other address highway, and each computer is arranged to address its non-associated transducer with the same second address code convertible into the first address code by the converter.
Where the address codes are binary digital codes the converter may be an inverter for inverting a predetermined digit of an address code. The system may monitor the condition of the computers (FIG. 2, not shown) and enable a selected one of the computers accordingly. Each computer may be arranged normally to access its associated transducer and to access its non-associated transducer if a fault occurs in its associated transducer. A third transducer (303A) may also be provided.
