td-io is a JVS arcade I/O board designed to adapt older JAMMA-compatible cabinets to the newer JVS standard, used by modern arcade hardware such as the Naomi and exA. It features a number of independent systems to translate signals, drive cabinet hardware, and power JVS games.

The TD-IOs for sale are hand built in Australia. As these are hand soldered items there may be some variation between boatds. These slight variations in no way impact the function of the item. Each board has had the latest firmware installed and been fully tested and confirmed to be fully functional prior to shipping.
