Abstract
PURPOSE: To realize an automatic load process for the control program by writing the contents of the specific code control program into the main memory via the magnetic drum in case it is decided that the specific code control program is shown from the floppy disk.
CONSTITUTION: CPU1 performs the address designation for floppy disk 9 based on the address data of subaddress register 24 given from ROM5, reads the specific code showing the memory contents at decision circuit 22 and then decides whether the specific code shows the control program. In case the specific code shows the control program, the contents of disk 9 is read out and then written into magnetic drum 10 to be transferred to main memory 4. After this, CPU1 starts the control action based on the control program written into memory 4. Accordingly, if all conditions to be loaded into the control program of the operating system are satisfied, the load process can be carried out automatically for the control program.
