I am building a small layout with 8 separately powered sections and 8 switches. I am considering how to build a control panel. Since it is a small layout I'd like to be able to disconnect it for relocation. The thought I was having was to use IDE (hard drive) cable and connectors as a bus between the layout and the power and switch controllers. Obviously i did not go DCC sign1 So i am going to have 40+ wires!
