Commercial AIM-65 Video Controller?

Any idea what this thing is? https://imgur.com/a/aNFiK Didn't come up with much of anything with Motion Control, Inc. I did plug it in, and it seemed to come alive. I tempted fate again and plugged a composite video source into the input, and a monitor into the output. One pot on top adjusts the vertical sync, apparently; other than making the colors slightly weird, the video came through more or less the same. The other two (marked Y and Z cal) seemed to change nothing. The switch mounted behind the pots caused the LED display to change (as seen in the pictures), though the switch mounted closer to the right side of the unit seemed to make no difference. When I get done moving, I'll dump the EPROMs and get more pictures, especially if there's sufficient interest. Thanks, Kyle
