No longer need the security chip. I think that is working when I boot through the megajamma board. It boots, you can add coins and play but no picture or guns. I took out the neck board and chassis board and took them to a local person that does repairs. They will be tested and re capped. One thing I noticed is when I discharged the monitor to remove the neck board I did not get the pop you normally do. I made sure to discharge a few time to be safe.
