I bought this exactly same card as in here: https://www.recycledgoods.com/itt-400980-001-ega-video-card/

Here's also the fcc if: https://fccid.io/FLN6RJMBC-EGA

The problem is that I need to figure out the jumper settings to disable parallel and serial connection but I couldn't find anything else besides those two sources.


I found a very interesting thing about this card that it seems like its EGA works faster than normal EGA. Does it contain more memory than 256kb or what could make the difference? I mean, there are a lot of EGA games which works seamless with VGA card but in real EGA might lag a bit in cutscenes etc but with this particular EGA card all the scenes are working like seamless.
 
How nice. After some time testing the card it suddenly froze the game and then brought me memory parity error and after reboot it doesn't go anymore into 350 line mode. Faulty memory chips in the ega card? I can still use the EGA in 200-line mode and it doesn't give me errors anymore.
