PURPOSE:To change a system for various uses, by automatically changing a signal line to be connected to a socket which has been prepared at the commencement, in a microcomputer system. CONSTITUTION:A microcomputer system is constituted by coupling a CPU part 11, a memory part 12 of ROM and RAM, an I/O part 13, and a control part 14 with a common bus 9. In order to change the socket connection of these memory part 12, I/O part 12 and control part 14, the respective corresponding signal line change- over devices 17 are provided. An address decoder 15 makes a data to a data conversion part 16 effective only when an address has been accessed, a prescribed data conversion part 16 and signal line change-over device 17 are selected, and a socket connection of the memory part 12, and I/O part 13 and the control part 13 is made a prescribed connection which has matched an LSI. |
