Hello!
I've got a New Shelf-Mount Wells Gardner PD199500 19" Tri-Sync monitor for sale. I only plugged it for a little bit before realizing it isn't really what I was looking for.
It apparently does CGA, EGA and VGA modes, but seems extra picky about CGA and EGA through the "standard" connector. I think if you were to wire everything through the SVGA plug, it'd work fine.
It works great as a VGA monitor, so it'd be great for a MAME cab, or one of those multigame boards that use VGA.
I'm looking to get $200 plus shipping for it. Thanks!
