Has anyone had any experience in the pin outs for group control boards and there connection to the main control board. Using a ProEl.Ind or Gicar board. Is this ribbon cable considered a standard pin out. Trying to source a replacement control box for a Bezzera Classic 2grp machine. Currently has a ProEl.Ind control box that is brain fried. I have had a bit of experience with auto fill boxes on single group machines but I’m unsure about the keyboard wiring on the multi group machines. Any help would be appreciated.
