This issue started when one the coils (underground pass) stopped working. I did all the usual testing to rule things out.
After ruling out everything but the MPU I decided swap the original board with a Rottendog board. I swapped over the chips and when I turned on the machine I get a single bong and nothing else. No GI no DMD. Coin door lights are on. LED201 on the MPU stays on. LED203 is off. LED202 is on.
Wondering if I screwed up one of the chips moving them over. I had to straighten two of the pins on CPU chip. I've not had any issues with Rottendog boards before. Any ideas?
Thanks
