<p>PURPOSE:To eliminate a writing device to be exclusively used by equipping a write mechanism to write data from the CPU of a computer main body to a ROM which is mounted on a board. CONSTITUTION:A board-shaped ROM memory 4, for which a write mechanism 6 is provided, obtains a mechanism to be inserted to an extending slot. At first, a CPU2 outputs a write allowing signal to an allowing mechanism 9 by a keyboard 3. The mechanism 9 receives this signal and turns on a ROM writing mechanism 8. Simultaneously, the CPU2 outputs a ROM writing signal to the mechanism 8 and a ROM5 goes to be writable. After that, the CPU2 writes information in a main body side memory to the ROM5. Thus, the exclusively used writing device is eliminated and operation goes to be easy.</p> |
