Or that use old machines because they work and their entire workflow is based on it. Like, I remember someone (might have been LGR… it was some retro computing youtuber at least) mention that they knew a print shop or something that was still using like win98 or 2000 for their entire production (as in, handling the printing, setting the size etc.) and maybe even the sales terminal…

And I’ve read horror stories of places like machining shops running their cnc setup off of a win98 machine because the cnc router or whatever it’s called just won’t work over anything but parallel port, or that the software needed for that specific router doesn’t run on newer machines.
