Hi all! I'm a longtime (guest) lurker and finally decided to create an account. I hope I'm posting this in the right place.

I recently acquired a Hyundai 8088 PC. It appears to be complete. It powers on and I can hear it counting RAM. I also hear the hard drive and floppy drive being accessed with the appropriate LEDs lighting up.

I can't get it to display. It appears to have an ATI CGA card. While I knew this was a longshot, I purchased a 9-pin D-SUB to VGA adapter to connect it to my older 19" Envision flatscreen monitor. No display. I wasn't that surprised. I fiddled with the dip switches on the motherboard using this for reference:

I also tried different DIP switch settings on the original card:

No go. My monitor can accept digital and analog input. Changing that didn't help either. I then purchased a known-good EGA card with composite output. It's a Paradise PEGA1A card. I still can't get a display on my monitor on an old 32" CRT.

Also tried different settings on the EGA card:
https://stason.org/TULARC/pc/graphi...GITAL-CORPORATION-EGA-CGA-PARADISE-AUTOS.html

For both cards, I also tried different ISA slots.

At this point, I'm out of ideas and hope I could get some help. Will I have to find a 9-pin CRT to get a display? Is there another converter I need to make this work? Could there be something wrong with the system board itself? I appreciate any suggestions!
 
You have several alternatives:
Get an 8-bit VGA card. Probably the easiest since many displays still retain VGA compatibility though some widescreen monitors will automatically scale the image to fit the width. But even a distorted image is viable for initial testing.
Get something like https://www.mikesarcade.com/cgi-bin/store.pl?sku=GBS-8200 which converts the original signal into something newer displays can handle. Many different implementations of the concept; example chosen because it was the first one I could find not as a recommended product.
Find an old display. Multisync (and its counter parts from other companies) which can handle CGA, EGA, and VGA are the most flexible. Finding a working model will take time and shipping will be quite expensive.

With rare exceptions, the two RCA jacks on an EGA card are not composite video outputs. They are "feature connectors" which were basically never used for anything.

That Paradise EGA card is certainly not an exception. The RCA jacks on that card are just dead weight.
 
It’s probably easier to get an ISA VGA card. I have a 16bit one that also works on 8bit machines so I believe there are others that will do the same.

I'll keep an eye out for a VGA card, but I like the idea of the converter. Thank you for the suggestions!
