Sorry to take so long to get back to you. Yes, that's the one.
As for the problem with your eject to trough issue, I'm not quite sure what to make of that.
You say that you can manually get the coil to fire when jumping the transistor ground leg to a good ground? Yet, in game play, it has a weak pulse?
I have just recently found a bad connector that caused a similar problem... I'd say that the logic seems to be working if you get a weak pulse, but that the connection isn't quite good enough to get all the juice to the coil.
I know that sounds simple, and may or may not have any bearing on the issue, but like I said, I've found connector issues to be the number one issue for bad or intermittent (weak) switch/coil/lamp functions.
Realizing it's a new board, I will say this with nothing against Rottendog. But I recently purchased a new NiWumph board that was faulty from the manufacturer... had a bad batch of capacitors on it, which caused all sorts of problems when installed in the game, and only after it warmed up!
Is it at all possible that your Rottendog board could be at fault? We take for granted that these things should work perfectly right out of the box because they are new, and granted, in most cases they do.. but for the most part, these parts are being produced by smaller companies, with small budgets, and of course, may not have the capacity, time, budget to always check quality control etc... Again, nothing bad meant towards Rottendog or their products. Just a caution that maybe the board could be the problem even though it's new. I have the experience to say it happens.
let me know what you want for the plastic, I'd love to be able to put it in my customer's hands.
