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 (*).
