<p>PURPOSE:To reduce the procedure of parts management and to prevent the error of memory mounting, by connecting a jig to a machine and accessing the memory of the machine with a different address from the one which is generally used when the machine is used as a signal unit basing on the copy control program and by copying the contents of the master memory to a machine memory. CONSTITUTION:When making copy, blank ROM's are mounted at the specific position 84d1-815 of a machine 1, and copy the contents of master ROMs 111-1116 to the ROM 81-815 of the machine 1 according to the copy program from the copy control ROM 12 of a jig 10. In this case as the one side input terminal of an AND gate G1 of a logic circuit 16 is grounded through terminals 1e, 10e by the connection of the machine 1 and the jig 10, the ROM 81-815 of the machine side cannot be accessed with the address which is used when the machine is used as a single unit. Therefore, the access and copy is done using a different address according to the copy program of the copy control ROM 12. In this way, the procedure of parts management can be reduced, the errors in mounting the memory is prevented, and productivity will be improved.</p> |
