This is a genuine Sega Shadow Dancer JAMMA arcade PCB (System 18, 1989), imported from Japan.
It includes the original DIP switch settings/wiring instruction sheet. The board boots and displays the attract screen with correct audio (see photo). It is in used condition consistent with age, so please review all photos carefully.
Known issue: the screen image shakes or wobbles slightly up and down. The cause has not been identified (it could be a monitor/setting issue or a board issue), and the board is sold as-is with this known issue.
