<p>PURPOSE:To improve the write efficiency and to reduce the write process by providing an ROM matrix having a required number of sockets to mount ROMs. and allowing a virgin ROM mounted on a socket selected via a controller from a CPU to be written with a master data registered in advance in an external storage device automatically. CONSTITUTION:A required number of virgin ROMs 5 are set to sockets of maximum n-set in number. Then a desired data is inputted by starting a CPU6. When the control of the ROM matrix 4 is operated by the software, a changeover switch 3 is thrown to the auto position. When the input is finished, the CPU is started. Then the CPU6 outputs a logic signal commanding the connection of the N-th socket and a data line to the ROM matrix 4. The ROM matrix 4 receiving this signal connects the N-th socket to each line of an ROM writer 12, and after the end of connection, the CPU6 extracts the master data of PART No.000 designated before from a disc memory 10 and gives it to a data line of the ROM writer 12.</p> |
