Quoted from bluespin:I read a vid1900 post that said to replace .100 pins with .156 pins on old Bally and Stern boards as the .100 are unreliable.
I buy from Great Plains Electronics G-P-E some people buy from Digikey or Mouser.
I think you misunderstood what vid1900 said. .100 and ,156 are 2 different sizes and are not compatible with each other.
Can you post a link to where he said that? You have me very curious now.
