What issues and for what game? I am pretty sure there is a lifetime warranty on the boards if you send it to them. I just hope that you will not mention that the board is currently in a system 7 game, as it has been known for a while about sound issues in most sytem 7 games.

ChrisHibler would be happy to look at it.

Can you post a picture of the board? Which IC's were you asked to swap?

I know I had read a lot of the boards having NVRAM issues, even replacement ones from Rottendog. I understand it is a special NVRAM for this 327 board.

Is that your actual board? Just wanted to help confirm the part is in the right direction. You may want to remove it to be sure you did not bend any pins putting it in a socket. Also tried the old part?

I would put the original part back in to see if it boots again.

I am not a fan of Rottendog MPU or driver boards, pretty much for any game.

LED displays for system 11 and Data East I have used and never had issues with since these have much less things to fail on them.

K's Arcade also repairs Rottendog boards. I don't know who else does.

The Rottendog board? If so, is it being replaced?
