RichardL has me beat. I was going to tell about my time working on 80 MByte Hard drives the size of a two-drawer filing cabinet, and how we used to be able to take them apart and fix things on them instead of just throwing them away and getting a new one. I used to have some crashed 14" dia. platters, but lost them somewhere.
And a daisy wheel printer is like a typewriter, but all of the letters are on a little arm. All of the arms were connected to the edge of a little disk, and they looked like the petals of a daisy (sort of). The printer would spin the disk to the right letter, and then a little pin would whack it against the page through an ink ribbon. Then it would move to the next, and so on. To change fonts, you had to change the disk.
