What sort of signal? Surely not composite video. EGA
resolution
isn't composite video. I was talking specifically about the IBM
You can have composite video for any scan rates, although finding a
monitor that works with it could be 'interesting'.
However, The IBM EGA card (and I would assume the clones) can drive a CGA
monitor at the standard (TV) rates. No, you don't get the higher
resolution modes, but IIRC you can have more colours than on a CGA card.
For that matter, the EGA card will also drive an MDA monitor at the MDA
rates, and has a graphics mode that's not the same as hercules...
But on an IBM EGA card (as I, and others, have pointed out), these
connectors essentially go nowhere, just to pins on the feature connector.
