I was doing some board testing in my Ms Pac Cocktail and after all the testing was done I put my once working board back in and think that I had either the VRAM addresser or the Z-80 sync buss controller put in wrong. Well now after I corrected the orientation of those cards the game boots and goes to the start screen but as soon as I hit player 1 or 2 I hear a clicking and the game resets. If I just leave it alone it just sits on the attract screen but as soon as I try to start a game it resets. I have unplugged the coin door so its not the slam switch and I have check all the voltages and everything looks good. The fuse block has also been replaced.
So my question is did I fry one of those boards when I had them in wrong? And do the symptoms that I am showing coincide with a fried VRAM addresser or Z-80 sync buss controller? Any help would be appreciated. Thanks
