In other words, it was basically a self-contained frame buffer. The problem is that such a third-party peripheral does not receive much support from software publishers, until so many units are sold that it becomes advantageous to support it from a merketing perspective. The Hercules graphics adapter for the IBM PC was one of the few such devices that received much support, apart from ones officially sanctioned by IBM. I suspect the only reason there is even one piece of commercial software that uses Apple's Video Overlay Card is due to the fact that the VOC was backed by the Apple name.
