I have seen these before, in another life as an audio/video technician. These plug into the video processor board on older Grass Valley equipment, like the 100 and 200 series production switchers. I believe - but this is where I enter the realm of speculation - they are ROMs containing the code for different effects. The utility processor board has a DEC J11 processor on it.
