Using a pencil and an eraser, unruled paper, and leaving lots of space between a line and the next (and, in extreme cases, a pair of scissors and some Scotch tape) you can do “incremental editing” (or a good approximation thereof) even without a computer.

Also, I’ve heard about people doing first drafts on note cards, which seems to allow for much easier editing of small passages as you go.
(Even without scissors, you can draw a square around a paragraph you want to move and an arrow pointing to its new place, and stuff like that.)
