Looking into the above, not the Logic as with the relevant connectors disconnected, the fault disappears. The castle lock solenoid keeps operating (every 10-15 seconds) which leads me to suspect the opto on that.
Alternatively the 10 opto board, the soldering on it is a bit dodgy, the LM339's have been socketed, I replaced the IC's just in case but no change.
If i unplug the top connector on the 10 opto board and plug it back in, the fault disappears until the game is rebooted which could still be a dodgy/weak opto on the castle lock.
Is there a good source of the opto pairs anywhere in the UK?
There is a kit of circuit board and components for the 10 opto board that i found which i am considering just to eliminate it and tidy it up a bit.
Thoughts??
