I hooked it up to my B&K 1077 and tweaked as best I could. There are a few issues to resolve:
The top is clipped.
The brightness increases from top to bottom. You can see that in the earlier pictures too.
The upper-right corner is dim.
I've done the best I can with the ion trap magnet, focus coil and yoke. Any thoughts ?
I think I'll poke around the vertical circuitry first to fix up the top of the picture.
