I just received that monitor that was sold on eBay as a color EGA monitor.

I’ve tested with a TTL EGA source on the DB9 port and it works as intended.

I was wondering if it could also work with analog VGA. Maybe through the DB25 port?
I scoured the web for the pinout but couldn't come up with anything. However I found info that suggest that this may indeed be a multisync monitor. E.g. https://scontent-ams4-1.xx.fbcdn.net/v/t31.18 … HZQ&oe=6485D37C

Does anyone have information or suggestion before I open it up?

Just noticed that there is a topic about the same monitor (relabelled as a Gateway 2000 CrystalScan 1024): Anyone ever see one of these Gateway 2000 CrystalScan 1024s with both DB9 and DB25 inputs?
The same question about the purpose of the DB25 is asked but without any answer yet 🙁

I have poked in the DB25 connector with a multimeter in continuity mode just to discover that pin 6 to 10 are ground and that there is no connection at all with DB9 (except pin 1 to GND).
I'll continue investigating...
