A communication terminal connected to a telephone line for playing a game with an opponent through a telephone line, includes a display board for displaying the game, a touch panel provided on the display board to detect a coordinate to be displayed, a touch signal detection circuit for generating a position signal corresponding to the coordinate, and a display board drive circuit for displaying the position signal on the display board. A PB signal transmission circuit is provided for transmitting the PB signal indicating the position signal to the telephone line. A PB signal detection circuit receives a PB signal from the opponent and converts that PB signal to a respective position signal.

Communication terminal used as a game machine

A data processor system is set up with, at least, a main memory and a central control unit. The main memory stores therein instructions to be executed by the central control unit. The main memory contains therein an even part buffer and an odd part buffer which momentarily store prefetch instructions of even addresses and odd addresses, respectively. The thus buffered prefetch instructions are sequentially fed from these two buffers alternately to the central control unit.
