WPC display and DMD controller board versions

The alphanumeric games (Funhouse through The Machine BOP) use display driver A-12739-1. Board A-14039, bare board 5760-12710-00 REV 6, is the dot matrix controller for pre-WPC-S games (Terminator 2 to Popeye); A-14039.1 (5760-12710-12) was used on WPC-S games (World Cup Soccer to Who Dunnit). The two are plug compatible. WPC-95 has no separate controller; the A-20516 board does it.
