Model 1 board, does this look normal?
I took apart My model 1 to clean it up etc and while looking around I came across a spot where it looks like a trace was damaged. I’ll post pics of the top and bottom of the board so you can see. The spot in question is circled in red.
So I somehow found a post on sega-16 about a genesis with a resistor on the bottom with a cut trace, exactly like mine. I'm starting to think this was just some factory "fix" or "repair" rather than a mod. Second post has a working image link which shows the same kind of resistor on the same spot with the trace cut.
