At one point Bill Burger on ebay had dozens of mahjong boards up for sale. I'd bet he has more laying around if someone was looking. Most recent addition: Heavy Metal Geomatrix Naomi loose cart with no case, lol...$30 shipped form the UK. plays great!
not from the mahjong point..it was arcade collections in front of thread . if you discuss mahjong exclusively.. well.. you'll be not alone but feel a little lonely yes ^^ fact we deducted with psikyo is some are joystick controlled, and so it needs a special dongle to redirect on real mahjong panel. play mahjong with a joystick? that is not true spirit, better do harakiri ^^
He probably has but most of them are probably well overpriced anyway. Some later boards, Psikyo ones for example have dual connectors on the board so they can be played in either a JAMMA or Mahjong cabinet, although on ones that have been used correctly there is a sticker across the JAMMA connector saying "Do not connect".
