    I'm looking at frame grabbers for our VME-based Suns.  Our
    application is real-time vision for a variety of robot systems.
    Our greatest need is to get full-color images from video
    cameras at full frame rate (30 frames/sec) and be able to
    access them from a Unix program (probably through memory
    mapping).  Currently, we can get images from mapped memory 
    at 15 frames/sec.  I expect that full frame rate would require
    double-buffering with two frame buffers.  Other attractive
    features would be:

	*  Overlay planes

	*  Simple on-board processing

	*  Occupies few slots

    We have looked at Matrox's MVP board.  Has anyone had any
    experience with this board?  What other boards can do what
    we want?

    Thanks!
