PURPOSE:To avoid the undesirable operation without provision of specific key switch, by cutting off the power supply, when the keyword information specific to the system and that inputted are compared and in uncoincidence. CONSTITUTION:When the 1st direct memory access DMA transfer from a floppy disc device 12 to a RAM3 is finished, CPU1 compares the keyword information set and stored in the internal register from the key word setting section 6 with that stored in the RAM3. If the both are in coincidence, all the program information is loaded from the floppy disc device 12 to the RAM3. If not in coincidence, the CPU1 supplies the power-off instruction to the power supply control section 14 to cut off the power supply. |
