ABSTRACT:
An interface system for use with an electronic computer including a CPU, a main memory, an input/output channel unit to which a group of latches is connected by a ring transmitting path and adapted to serve as a serial register, and a service processing unit including an operator's console control unit for performing a resetting operation or the like for each of such units, wherein the service processing unit affords read/write operations of data transmitted from the serial register by itself, and which is characterized by an additional console shift register provided in the input/output channel unit, which allows an interface to be implemented between the input/output channel unit and the operator's console control unit by the reading/writing of data into and from the console shift register.
