All boards have been checked. I reflowed all the connector solder joints and inspected all the wires. All good. The battery holder was replaced. All fuses were removed and checked. Many were incorrect, so I've fitted the correct value fuses.

One coil was weak and was replaced during testing. The game is basically completed. I'll take some photos of the machine over the weekend. Plays very well and is an underrated SYS11 game. Very happy with the result and the new owner will love it !
