    Patent number: 3986169
    Abstract: In a multi-computer system having input/output devices for common use, protection is made for the devices upon transferring of the input/output data by comparing a device identifying number or address signal and a number signal identifying a central processor unit which demands the transfer of data, thereby to determine on the basis of the result of the comparison whether the data transfer between the device and the central processor unit is allowable. When the transfer is not admitted, the input/output operation of the device is inhibited.
