AFAIK, on the original EGA, the answer is "they go to the expansion
connector". No signals at all; NC, unless there's some sort of EGA
expansion interface installed, such as a genlock board, in which case one
is video in and the other is video out. On the IBM schematics, they're
just labeled "EXT VIDEO" and "VIDEO".
