What about systems first thought up and used before magnetic storage disks of any type, floppy or hard?
Machine manufacturers making machines for various manufacturing purposes, in my case, plastic injection moulding machines for a plastics moulding company, brand new machines some five years ago were still running prorammable machine controllers which relied entirely on E Prom chips. No hard or floppy drive of any sort, all machine function programs stored on a chip that can only be programmed by ultra violet light beams. In fact if exposed to a strong source of ultra violet the chips could be wiped of all data.
No doubt other types of industrial manufacturing machines may still be being made with such an old technology in them.
Why all the fuss, I already have Windows 8. Three windows at the front, and five at the back since I bought the house.
