That is an online transcription of Claude Shannon's thoughts on the matter. Google pointed to this link from Sharif, but you can see a printed version in the second volume of his collected works, I believe. I ran across this during my blissful graduate student days.

I love how this talk ends with him asking his audience to come and look at this machine that he built.

When I teach my courses in EECS at Berkeley, I always use the board. In fact, most of my colleagues whose offices are near mine all use the board most of the time. We know that students don't like powerpoint and it isn't good for them.

Many students need the (eye+ear)-to-brain-to-hand-to-eye-to-brain loop to internalize the material. Watching the Prof. write on the board engages some students taking notes better than the flash of instantly appearing powerpoint. Especially when diagrams and equations are involved.

Yes, it's a pain to walk out of lecture covered in chalk dust, but it's what is best for the students. After all, my anecdotal experience has been that those few students who get more out of seeing powerpoint slides than the blackboard also tend to get a lot out of just reading the textbook on their own and asking questions in office hours. While those that resonate the most with the blackboard tend to get less out of just reading the book on their own.

Men love to wonder, and that is the seed of science.
