On a much different scale, I ran into a similar problem once. Not for me, but for a customer. About 10 years ago I did a PC breakfix job onsite at a small business that made trophies. Their main business was bowling leagues and other local sports. The computer I was there to fix was fine. But the computer that ran the engraving machine- the one that they made all their money with- was an IBM PC/XT from the early 1980's. No hard drive, everything was on 5.25" floppies. I mentioned that they should replace that thing sooner rather than later, but their objection made sense for their use case: The replacement would be many thousands of dollars and this old setup still worked. The computer had one job, and it did it. Who knows, maybe it's still there, still mashing away on its floppies every day. It wouldn't surprise me. If it is, it's being held together by nicotine deposits and luck.
