I have a couple of ega cards, one is a dual output 16 bit ISA video card, with 9 pin and 15 pin connectors. The dip switches do indeed change between ega, VGA, cga, mono modes etc.
I'm just using an ega only card but I don't notice much difference in performance.

I believe I saw a couple of those dual ega/VGA cards on eBay recently for a reasonable price.

I just got my first EGA card, although I haven't actually received it in the post yet. It sounds like one that DonutKing has - that is it's a 16-bit dual output ISA card, with both VGA and EGA connectors. If I use the EGA connector, will it give good CGA compatibility?! 😀

If its like the one I have you can set the DIP switches on the back of the card to output in CGA mode.

I think it was common for some early vga cards to have both vga and cga/ega connectors. I have one like this : http://82.114.193.227/vga2/index.php?option=c … dent-tvga8800cs If I remember well, the db9 output could be configured between cga and ega using the dip switches and some jumpers.

Yep if you look for more similar cards, you can try searching for Trident 8800CS and some ATi EGA wonder models too. Mine EGA wonder even dont have switches - detection is automatic = less work.

Edit - forgot that Tseng ET3000AX have dual output too.

Edit2 - forgot again - check also Oak OTI037C

I just got this thing. It's got VGA and EGA. Unfortunately, I haven't had time to test it yet.
