    ----------------
    I have the 16K version, this it the program that I ran, here are the results:
    ----------------


    When the program runs this is the first set of characters that appear on the screen, but you have to be quick, they only stay visible for a second.


    After the screen clears, this is the 2nd set of characters that appear on the screen.

    Thanks very much!

    It is just match to Japanese PC-6001.
    That means PC-6001A VDG is same as PC-6001.

    VDG : M5C6847P-1 ( Mitsubishi, compatible with Motorola MC6847 )

    The font is nearly same as MC6847's PAL square font except (*).
