摘要: An input/output processing system comprises a number of modules including at least pair units connected to operate as logical and interface unit having ports. Each port connects different one the for interconnecting pairs communication over switching circuit networks included in unit. The further includes control logic circuits disconnecting each processor preventing disconnected from communicating with other modules. include which response special commands good are operative condition via line, apply status signals representative contents register within command certain loading into registers subsequent analysis by routines.
