The Muller-Fokker Effect — John Sladek

Can a human being be reconstituted like orange juice?

To find out, the Army backs a futuristic research project that transfers a man's personality onto computer tapes. Guinea pig for the experiment is technical writer and dreamer Bob Shairp.

But the project barely gets off the ground when a computer accident wipes out Shairp's mortal body and only his tapes remain. Is Shairp doomed to this encoded state forever? Or can the bizarre process be reversed?
