Your Holo isn't showing up John, mines blue too! He's green when you look at him without the lamp on but in the game he's blue (depends on the angle you look at it too)
I think the center of the apron is just a sticker, I don't believe that mine is screened.
The magnetic reed switch is interesting, I had read about it in the past but never seen one, how does it go when the ball falls away from the edge of the bowl? i.e does it still count the revolutions or is it only within a certain distance (do you get more letters lit than a standard switch?) Is the sensitivity adjustable?
Nice work on the switches too, I wish I had a rivet press, I usually end up using a bolt and nut because I can't get a rivet back in.
I'm glad you decided on a new playfield window too, the old ones just don't come up as nice as a brand new one.
