Fully tested, original Apple Macintosh II High Resolution NuBus video card. This came in two versions; 4-bit and 8-bit. This is the higher spec 8-bit board that could display up to 256 colours at 640x480px.
It is not compatible with the Centris/Quadra 660AV but can be used in any other Macintosh with NuBus slots. It is an unaccelerated card supporting standard Mac resolutions of 512 x 384 and 640x480px. Rear plate may have some corrosion but the board is fully functional
