Expect to sell an arm and a leg when going to Taito, did an enquiry once for the Sega to Fast IO conversion board and harness, was over €400 without taxes and shipping...
lol Bally said I could have on repaired for 52K yen.
I saw one sell for 2000 yen on YAJ, but it was at a time when I didn't need one, kinda regret it now. I mean I have the Taito -> Sega conversion pcb so I could always go the Sega route. Or if the pinout is the exact same, I could maybe just cut out notches for the hirose harness and plug it into a sega i/o directly.
