Abstract

PURPOSE:To simplify editing and a retrieval of a data by bringing a bus monitor device to a successive connection to a central processor to which plural units are brought to a successive connection by a bus, and providing a means for editing and retrieving a data of the bus on said device. CONSTITUTION:A data which is transmitted from a central processor is inputted through a bus connector 8, and also, passes through a bus gate driver in a bus monitor device and transmitted to a unit. The data reaches a selection instructing circuit 13 of write by a bus in the bus monitor device, and a data inputted to a memory 12 is selected therein. For instance, when a specific address is brought to an access, when a specific data such as 'FFFF' is written to the specific address, a condition such as the time of generation of a parity error is set in the circuit 13 by a selection of a keyboard 21 and a command from a control part 11. When the condition coincides, a gate 15 is opened by an output signal of the circuit 13, and it suffices that a prescribed input data is written in the memory 12.
