It's exactly what it says. It's a Radius PrecisionColor 19. It's a NUBUS video card with just Video out, and supposedly some accelelerator function. It comes up, and I can view the video output from either onboard or the card, without having to remove the card. It reports as a PrecisionColor 19. I have found very little about the card on ebay.

I have RadiusWare installed, but no way to change resolutions.

Currently using an Apple MultiSync 17" (720 Display). And on the Quadra built-in video, I can change rez. On the Radius, I am stuck at 640x480, except I can change from black & white all the way up to millions of colors.

I am scratching my head. The card came with the Quadra, but I can't find drivers nor very many references for this.
