Abstract
PURPOSE: To always ensure the supervision for the contents of the memory by compounding the output of the hexadecimal digit generator and the output of the synchronous signal generator through the video signal generator and then sending the composite output to the CRT.
CONSTITUTION: Memory 4 is controlled by the read/write signal sent from the microcomputer, the address signal and the data signal each. Switch circuit 1 operates on the chip selection signal given from the microcomputer to control the read/ write for the memory. Here address signal generator 6 synchronized with the signal given from synchronous signal generator 5 to generate the address signal and is actuated by the chip selection signal given from the computer to switch the address signals given from the computer and generator 6 to apply them to memory 4. Then the output of hexadecimal generator 9 is compounded with the synchronous signal given from generator 5 through video signal generator 10 to be sent to the CRT in the form of the video signal. Thus the supervision can be always given to the contents of memory 4.
