I have two PCBs that have collected dust the last four years. They were all working at the time I tested them, but static could have shorted some of the fuses. I'm willing to send the PCBs first for you to test them if you have a good trading score or reputation as I no longer have my Jamma harness. I could probably test them out locally first if I had the time, but I'll assume they work. I'll take anything console or electronic related as trade.
You can PM me for contact details.
