I acquired this interesting ET4000AX card, which has a composite output (and also S-video and a mysterious 9-pin connector).

Does anyone know what can be made to come out of its composite output, and how? Particularly in DOS, though I'm curious about any way of driving it.

(Sorry for the bad photos.) [Edit: see attached for photos.]

I know that some EGA cards have composite output that only generates sync. But I'm still hoping that that this one can also generate video... maybe?

The only documentation I've found for the card is here (but it doesn't say very much).
https://stason.org/TULARC/pc/graphics-cards/U … A-VIGA-VGA.html

The best scenario would be if I could enable colour burst in CGA emulation mode, to enjoy artifact colours. I've found a utility that can turn on the CGA emulation, and that works pretty well. Still, no clue how to enable the composite output, never mind with colour burst.

Much obliged if anyone has any suggestions!
