I can't imagine what it would be like to use a computer in general, without sight. However, most programming resources are in text form, so I guess it wouldn't have been too difficult (in relative terms).

I've done a little commercial web dev so have used freely available audio-browsers. A very interesting experience.

YouTube has examples of people programming using audio output. That should help to imagine it.
