bump! still looking. The filter board I seek is located between the harness and pcb itself. Its not needed for normal operation of the game, most people remove theirs. I thought mine had one, but when I opened the backdoor to retrieve it, It didnt have one. Anyways please lmk if you have this board for sale.
Is the Punchout Filterboard the same as the PC-10 board?
Check out my WTB Playchoice thread. I am on the lookout for the PC-10 filterboards. I have another filterboard that isn't the same as a PC-10 might be what you are looking for. Let me know.
I have one and just replied to your PM. Someone soldered a couple of wires directly to the edge connector since I guess they didn't have a harness. I just unsoldered the wires. The edge connector is in good condition, you just need to remove the extra solder that on some of edges.
