Quoted from arolden:This makes sense however I don't understand how the problem disappears with the original MPU board. Does the Rottendog board pull more power from the 12v supply than the original board?
I doubt that the MPU is drawing more from the 12V line. If anything I would suspect a small variation on parts in the switch matrix section where is only becomes a factor in cases like you see. From what I understand that is one of their better boards and usually just works. I'll have to take a closer look at that sometime.
