I've seen companies still distributing software updates on floppies, for that $25k spin-a-ma-thingy in the corner with the proprietary interface to the Win98 PC, that keeps on working and delivering useful results. A famous example from the car industry is McLaren having a stack of 25-year-old Compaq LTE 5280 laptops, running DOS, because that's the only machine that will run the proprietary CA card module for the diagnostic software for the McLaren F1 (106 cars produced '92-'98, 100 left today, each valued north of $10 million).
