I carefully reseated U10, U11 and the 5101 chip. Test went fine, had about 5 games then same problem ^&^.

Then turned off and on only got 2 flashes ^&^

It then booted up and reset in the test phase ^&^

There's a credit button under the playfield when i push it to get credits it resets.

I notice in attract mode the extra ball lights won't flash whereas they did with the Seawitch MPU, the attract mode lights also flashed quicker with the Seawitch MPU. MMmmm maybe now this is a job for Ken?? What do you reckon?
