Locomotive D51 stuck in the station...

1F44C7C6-7202-48E2-B06C-199073BFF9B7.jpeg My guess is it is this one that Max posted. I have 2 and have considering offering one for trade here. I have seen very few of these posted here over the years. Maybe only one or two other than the one Max posted.

The one pictured here is what I have.

I'm waiting on my camera battery to charge, so pics have to wait.

As it turns out, I answered all my questions myself.

Under some crud, an ON/OFF switch was hiding on what can only be described as a primitive computer--the vintage electronics I referenced before.

3. The micro-switch at the end of the ball path is a counter; the center attraction counts up 1, 2, 3 with individual grain of wheat bulbs illuminating after each jackpot; upon the
third jackpot...

1. ...the solenoid fires, opening gates along the lines of a tulip opening.

2. Once the gates are opened, two balls down the center attraction trip the switch, closing the gates.

4. The tulip is accessible when closed, but the path is obscured by the center attraction.

It takes three, and sometimes four more jackpots before the center attraction starts counting up to open the gates. I don't know if that is normal behavior or not. I couldn't detect a pattern.

I think of the 7 machines I have, this one is most suited for a complete restoration. It works, but the play field is stained and it is missing one grain of wheat bulb.

Has anyone created a refit kit with more "solid state" electronics?
