Recently picked up the schematic for my new-to-me Gottlieb Domino which has been playing fine in 5 ball mode, and starting to poke around a bit under the hood.
The schematic led me down the rabbit hole of 3 Ball vs 5 Ball, there's a honking jones plug strip to make that change, and it seems to impact a lot of the playfield, and I wanted to check it out.
So far:
5 Ball: 2 of 6 top lanes light (alternately), pop bumpers alternate (red / yellow), and center target turns on periodically (1 of 3 cases)
3 Ball: 2 of 6 top lanes light (alternately, no change), pop bumpers alternate (red / yellow / all), and center target is always lit
Not sure if all this is right, but it seems (mostly) right. I'm have not noticed or dug into any differences in the captive holes (spin & advance), the roto targets themselves, or the side drains (advance) or center drain (spin).
I'm also looking at the Domino Advance setting (conservative vs liberal) and as far as I can tell, I'm not seeing much impact there. Base on the schematic, I'm guessing it impacts what will advance the dominos, but have not noticed it yet. The purported 3 ball / 5 ball instructions (3 ball instruction card not verified) show no differences, nor do the playfield instructions or schematic.
Y = (Captive side) Hole Relay
X = 100 Pt & Advance Relay
V = Roto Target Scoring Relay
Any Domino owners have a manual, other documentation, experience, or link to a thread here that might let me know what it SHOULD be doing?
