Quoted from johnwartjr:

Is the coin door memory protect switch by chance stuck closed? Can you test it with a meter and confirm it is working correctly?

This is what I'm thinking as well. Something isn't allowing writes to the RAM.

Ensure J114 is connected properly and no evidence of battery leakage damage in the area. Remove J114 from the board and try again.

Yes the anyPin would definitely need to be set to 6116, or the CPU jumpered for 6264. Since the board is booting though, anyPin settings are correct.

This isn't an anyPin issue, the CPU is showing the same issue as before the anyPin install. So also not likely a soldering issue.

The CPU memory protect circuitry is likely bad.
