I've been known to be wrong, but it doesn't look like it has to many smarts on it to me. Does it perhaps just lift the video out of the bus, and pop up a composite and rgb output?

That's kinda what I'm thinking: something that's just enough to drive either
an analog-RGB monitor or a CGA monitor. Whether it actually produces color
output or just treats the destination monitor as monochrome remains
anybody's guess (though I suspect it'd take even less logic (maybe none at
all) to turn composite video into a monochrome rendition into RGB).
It might even require you to run a cable to the composite-video output,
which would make the RCA connector on the board an input.
