In process of rebuilding my TOM and it seems all the Cabinet switch connectors ( J 212 & 215) on the CPU boards , currently IDCs are literally all breaking off. not sure if that is normal for the age? I have ordered replacement IDC's but am wondering if crimp connectors would be better and more resilient. I always thought that IDC (Insulation Displacement Connector) were designed for solid not stranded wire but the wiring loom seems to be stranded. I am thinking that IDC's were originally used because they were quick to fit and cheap!. Any thoughts
