Are Gottlieb System 1 4-digit displays compatible with Gottlieb System 80
I have a Haunted House where the 4-digit display will not display the number
1 but all other numbers seem to work fine. I would like to take the 4-digit
display out of my Sinbad and put it in HH to see if the problem is display
related or connector/MPU problem.
