Communication adaptor for game set

A communication adaptor for use with a plurality of game sets each provided with a first connecting means for inputting and outputting data on the state of a game and each game set including a buffer memory for temporarily storing transmit/receive game state data of the game states of the other game sets connected thereto, and for transmitting and receiving game state data to and from the plurality of game sets, said communication adaptor comprising:

• a housing;
• a plurality of second connecting means provided for said housing and each including at least a first terminal, a second terminal and a third terminal, each second connecting means including at least a said first, second and third terminal being connected to an associated first connecting means in one of the plurality of game sets;
• a data input port connected to the first terminals for storing bits whose number correspond to the number of said plurality of second connecting means, the bits being stored corresponding to the bits received from the first terminals included in the second connecting means, said bits being related to the game states of the game sets;
• a data output port connected to the second terminals for storing bits whose number correspond to the number of said plurality of second connecting means, the bits being stored corresponding to the bits to be transmitted to the second terminals included in the second connecting means;
• a clock output port connected to the third terminals for storing bits whose number correspond to the number of said plurality of second connecting means, the bits being stored corresponding to the bits connected to the third terminals included in the second connecting means,
• clock signal generating means for applying the same clock signal used for data communication with said game sets to said clock output port;
• transmit/receive data temporary storing means for storing transmit game state data on the game to be transmitted to each of said game sets and receive game state data on the game received from each of the game sets in synchronization with said clock signal;
• format converting means for converting bit serial data received from each of said game sets into bit parallel data and for converting bit parallel data to be transmitted into bit serial data;
• receive data writing means for writing into said transmit/receive data temporary storing means corresponding data out of said data input port which are received from each of said game sets and after being format-converted by said format converting means in synchronization with said clock signal;
• and
• transmit data supplying means for reading out the transmit game state data stored in the transmit/receive data temporary storing means to supply the same to said data output port after being converted by said format converting means so as to transmit the transmit data stored in said transmit/receive data temporary storing means to each of said game sets in synchronization with said clock signal.
