Abstract

PURPOSE:To dump the contents of a storage device independently of the status of a central prodessing unit (CPU) by starting optionally a storage dump program in a microprogram stored in the storage device even if the storage dump program for software is not feasible. CONSTITUTION:When an initial microprogram is not executed due to CPU default, the operational status of a trigger means TR is checked; if TR is operated, a control right is transferred to a microprogram PR of ROM. The microprogram PR controls a flopy disk controller FPDC and a flopy disk drive FPD and transfers the contents of a control storage device CS and a main storage device MS to the flopy disk. Even if the microprocessor MP of CPU is abnormal, the contents of the control storage device CS and the main storage device MS is easily known.
