Novellus Wafer Processing Motion Interface Module Multiple circuit boards inside including: RCL Enterprises SSI-C186EB Delta Tau Data Systems Motion Control Board Plus the proprietary boards This is used and was picked up at a govt auction. There is no markings as to who made this, but I believe this is Novellus because of the way the part number are displayed. We do not know exactly what this is or what it goes to. I am in the military reserves and will try hard to ship ASAP, but sometimes I am away on duty (which is why I have the 4 day shipping set) Will ship international.
