Hi
I wonder if anyone can help with this board please, I am trying to repair this board and no clock signals are present on the Z80 processors, the crystal and 7404 is all operational on the board, but i cannot seem to find where the 2 are connected, it appears the clock signal travels right away to the furthest point in the opposite direction to the clock generator!
Does anyone have any circuits on this board? its is made by SNK for electrocoin and has the numbers on it G4001UP01-2
I am gathering because it is SNK there is no info/ circuits around? can find nothing of use on the interweb!!
Many thanks
Andrew
