Abstract

PURPOSE:To enable to execute the processing of service request independently of the operation of central processing device, by processing the various service request from the service processing device and central processing device with the microprogram of the maintenance processor. CONSTITUTION:The maintenance processor 6 having the control memory device erasable is provided between the central processing device 2 and service processor 3, and to various service request from the central processor 2 and service processor 3, the interpretation of control signal and the giving/reception of data are processed only with the microprogram of the maintenance processor 6. Thus, even if the central processor 2 is not operated, the processing of service request is made possible. Further, the content of the storage device is changed to the microprogram suitable for the request, allowing to cope with the addition and alternation of service request softly.
