Quoted from gdonovan:One facet of this project which I have not mentioned is I have an eye towards making this a universal Bally/Stern cabinet where playfields can be swapped out in minutes. The hardest part would be sound, though I might just add a dual pole switch to swap the speaker and volume control from Stern to Bally with a flip.
This is what I am doing with a Star Trek cabinet & Magic playfield. Interested in what you come up with. I had to add a coin button to run Stern.
