it might be a multisyncer, seeing it has a 9 pin VGA connector (kind of contradictory
actually). Those models are few and far between. I know of 2 NEC models and 2 Sony models
that could display VGA (and CGA and everything in between). Come to think of it though one
of those Sony's could display anything but VGA frequencies (or Mac II era w/the proper
adapter), so there you go.
