The polling port P1 is exclusive for readout and performs refreshment of screen. The polling ports P1, P2...PN+1 are operative serially during the refreshment of screen and repetitive during the refreshment period. Further, at the start time of each memory cycle, whether the presence of data from the data generators 3I...3N or not, is discriminated, and if there is any request, the content of request corresponding to it is displayed on the CRT5.
