Even older hardware
Some older Tek DSO's can only be updated, etc with a floppy disk which is a pain when the drive belts have turned into glue and are made of unobtainium.
Once that internal memory or battery dies if you don't have the special disk your >£900+ 'scope will be only useful as a brick, gives a whole new meaning to "built in obsolescence".
