W9803D4 - Arcade claw machine board

Looking for the schematics for this board - its an offshoot of some Chinese board but branded for Coast to Coast entertainment

I think I narrowed down the issue I am having with the claw to a op comparator that drives a photo transistor, this seems to provide the ground used with a DPDT relay

I am in the process of trying to diagram some of the board, if no one has the schematic i'll probably post what I have traced so far
