PROBLEM TO BE SOLVED: To easily load and unload a microcomputer emulator device and also to facilitate the debugging jobs or a gate array and a memory at a development stage by providing the serial interfaces at the connection part between a disk device and the emulator. SOLUTION: In a debugging job mode, a serial signal line (serial cable) Sd is connected to the serial interfaces 15 and 23, and a microcomputer emulator device 20 is connected to a disk device 10 having a microcomputer. Then a test type setting switch 21a is operated to designate a test to be carried out, and a control part 22 outputs a test instruction according to the test that is set by the switch 21a. In such a constitution where both interfaces 15 and 23 are provided at the connection part between the devices 10 and 20, the device 20 can be easily loaded and unloaded and the debugging jobs can be easily and quickly performed. |
