RasterOps ColorBoard 64
The RasterOps ColorBoard 64 is a 12" NuBus card compatible with 680x0-based NuBus Macs running up to Mac OS 7.5.1.
Details
The RasterOps ColorBoard 64 is unaccelerated and supports only 640 x 480 resolution in up to 8-bit color.
Notes
RasterOps claims this card is only compatible with the Mac II, IIx, and IIcx; I don't believe them. If anyone can substantiate this belief of mine, let me know.
