might be different setup for BSD because of the long range opto?
Part numbers have unique suffix which might mean they are setup specifically for certain games.

Quoted from DumbAss:Here are photos from two different BSD 24-switch opto assembly boards. I agree with terryb in that I've seen errors or ambiguities in the parts list versus the schematic. The schematic is often (if not always) correct.
The schematic shows:
R9=470 1/2W
R12=10 (1/4W)
L1=10mH
On the board (if I interpret the colors correctly):
R9=470 1/2W
R12=0 (1/4W)
L1=?? (I don't have enough electronics knowledge to be able to figure this out)
Hope this helps.
The greasy spot around your C7 makes me think it might be leaking. I had a few opto boards in my BSD with leaking caps.
