Just picked up this early version scorpion that I believe during the pub time transformation. This has the old stg01 board that's two pieces as seen in the photos. So we have lights, display and sound. Coin up works as shows credits I believe all or most dart segments working as the alarm sound goes off. The service button (located behind coin mech) works but none of the buttons work. Cleaned PCB clean EPROMs and all wire connections. All grounds seam to be good..

Recap none of the buttons are working/functional
