A couple of questions.
1. How do I get the backglass off?
I've unlocked it using the key inside the door and tried to lift it like a normal pinball backglass but it doesn't even slightly move so I don't want to force it if that is not what it should do.
The manual doesn't mention it at all apart from the parts list in which it DOES mention a lift channel so I expect that it is like a normal pin, in that once it's lifted up it frees it from a lower lip and then you can pull it forward and out.
edit: figured it out. It's a normal backglass except that mine was glued in. I pressed it around the bottom edge and it flexed. I took a guess that it should be normal as i swear i'd see a jjp video if it being removed the same way. I put a heap of upward pressure and it very slowly started to move and then get faster as the glue started to split away. The glass itself had 4 glued in pieces of foam so there was no rattle in it at all.
Now I can't figure if the lcd screen bezel was showing through as much as it was before.
I've measured the lift channel in the head and it matches how far down I can reinstert the backglass.
2. When/what causes the ramp divider drop?
I've only seen it occur once and that was on a distributors machine but not on mine. I'm guessing its a specific mode that I havn't seen yet.
