PROBLEM TO BE SOLVED: To enhances the degree of structural freedom in a box body design of a game machine, modularize the ROM of a control board of a game machine, locate it in a position in a box where it can be easily detached (e.g. on the rear side of a Pachislot door) and the like, and enable the control board to be located in a box body rear box. SOLUTION: By fixing a bus buffer, a serializer, a deserializer and a bus buffer between a CPU and a ROM, the connection between the CPU and ROM is realized with an extremely high speed serial communication instead of a parallel connection bus. By converting numerous address lines and data lines to several pairs of transmission communication passages, skews between signals in this transmission are prevented from generating and the transmission through a harness is enabled.
