This is the Midway 8080 ram test board for Space Invaders, Gunfight, and Seawolf. It's mentioned in Midway trouble shooting manuals, but this is the first and only one I've actually seen.
Now, does anyone have instructions for this? I know the basics, of how to plug it in, etc, but I don't know what to expect to see in the segmented displays.
