2014-2017 I was supporting a clipper setup for issuing work order and many other tasks for an old civil aviation repair plant. I’ve ended up virtualising and moving it to a hyperv cluster. Definitely the case of “if it works, don’t touch it”. Also set up a closed network for CNC machines to let engineers in the shop send jobs over the net instead of running around with floppies or manually entering gcode through the console. Fun times.
