Battery holds ram data, coins in/out, percentage etc etc. That battery has leaked across several components, that may be the probable cause of the issues you are having. Board either needs repairing if possible or a new undamaged board needs sourcing as a replacement.

Yesterday,I visited Reelfruits arcade in Bognor Regis. Had a fantast asic time and played on quite a few of his machines. Managed to do a handful of videos too. At one stage it was like',This is Your Life' as Dave shouted Chris217 is here😂😂😂 I even received a gift of a model Network South East coach from Dave Snakes & Ladders. It was nice to catch up with friends I haven't seen for a long time, and friends off YouTube and even a member off here🤗 I tried to play sensibly as so I don't get drawn in too deep,and the days visit only cost me 20-30 quid in all. Great seeing all these classics under one roof and the place was naturally buzzing. When I walked past the arcade on the sea front,it was virtually empty. Arcade owners should take a leaf out of Daves book. Fantastic day and well worth a visit.

Hello there Enjoy your stay

The MPU4 video manual is available in the downloads area but you'll need to become a donator to obtain access.

As well as the usual track fixes If. it were me there would be many more transistors in the cup ;). I replace every transistor in the vacinity of the battery by default. All the way to the 555 & pio even if they look good. Only cost pence so I never risk it. Imo there is nothing wrong with the project coin reset circuit or the board it's made from as I've never had a board back with reset issues.... Just the original transistors let you down with green Hiden at the top of the legs. And I've worked some pretty rotten baors. Also need to go round trim all the legs on the solder side as they can short to adjacent tracks or components... Especially after a trip with royal mail. Lastly mpu off battery current is a good indication of the health of the mpu.
