Display system for transfer contents of secondary memory device

Abstract

Abstract PURPOSE:To confirm the working state of the titled display system from outside by displaying the data and said working state based on the decision of coincidence between the address of a set track and the working address of a disk device. CONSTITUTION:An optional track address is set before this display system works and a microcomputer MCP7 sets a disk in a data read mode. Thus a disk control part 8 sets the addresses corresponding to the track numbers, sector numbers, etc. designated by the MCP7 to an address register part 1 of a disk unit 10 via a data buffer 51 of an interface part 5. these set addresses are compared 3 with the set value of the track address. When coincidence is obtained from said comparison, the data and the working state received from or sent to the corresponding track by the comparison timing signal are stored in a buffer memory 41 of a working contents display part 4 via the buffer 51 and then displayed by a working contents display circuit 42. As a result, the normal working of a disk device is grasped based on the display of the circuit 42.
