A processor forms part of a computer network wherein the processor, designated as the User Interface Processor, operates to initialize and maintain and communicate to remote diagnostic terminals for purposes of confirming integrity of the system and also for finding the location of any faults or problems in the system. The User Interface Processor involves a microprocessor unit working in conjunction with a serial communications controller, random access memory and read only memory memories, a communications input/output (I/O) system, a multiple set of timer units and a priority interrupt controller. The User Interface Processor provides interfaces to a power control card unit, an I/O subsystem (of data link processors), and a remote terminal for diagnostic intercommunication.
