I've got a Philips 8088 XT equipped with a CGA card, which I hooked up to a Commodore 1084S-D1. I'd like to upgrade to EGA.
I've got this hybrid EGA/VGA card from Trident (8800CS), which also works in an 8-bit ISA slot:

I've been in the market for an EGA monitor for a while, but those seem to be hard to come by. I know that some EGA cards can be configured to drive a CGA monitor like my 1084S-D1, effectively forcing it to 200-line-only mode. It's not the full EGA experience, but definitely a step up from 4 colors. Unfortunately the docs from Stason don't really specify anything like that, so I was wondering if it's even possible with this card. I set J1 to pin 1&2 to get TTL mode. I've tried all possible settings for the first 4 switches, which seem to be controlling the video signal, but no luck. Is there anything else I can try?
