Typewriters as machines have not changed much. In fact, they thought they were going to be obsolete about 15, 20 years ago, but they're still around. Parts are still around. Typewriter hasn't changed at all.

Fax machines, printers they've changed. They've come a long ways. We go to schools for about a week and learn the new, but in theory, everything's the same. Really, I just go by experience is what it is.
