PURPOSE:To greatly improve the operability with the data display method for key input buffer by reading the data on the key input buffer set in a memory of a computer as necessary to recognize the unprocessed key input data like the key input data under processing, the preceding key input data, etc., and displaying these unprocessed key input data. CONSTITUTION:When a CPU 1 is set in an access state to a key input buffer 4, the data is read out of the buffer 4 via an address data line 8 for reference to those data on a head pointer, a tail pointer and a buffer counter. Then the presence is recognized for such unprocessed key input data as those stored in the buffer 4 ranging to the data shown by the tail pointer and that shown by the head pointer, i.e., the key input data under processing or those data supplied in advance when they are processed against the key input data supplied previously by the CPU 1. These unprocessed data are sent to a display part 6 for display.
