From what I am able to find out, they communicate via an IEEE-488 8-bit parallel multi-master interface bus that somehow makes use of an DB25 connector via 26pin ribbon cable. Williams didn't do their best with communications on this hardware. I hope this isn't a pain to implement. Long live Namco C139. -.-
