Is there a way to identify which DEC plant manufactured a specific piece of equipment? I'm certainly aware of the Maynard, Massachusetts label on my equipment and I'm pretty sure I've seen DEC Kanata, Canada on flipchip handles. Maybe even PR serial numbers on computers built in Puerto Rico. Can anyone supply any more extensive and/or detailed information? Thanks, Jack
