If anyone has more current information please e-mail me.

Christopher Seline wrote a well-known critique in 1989 of TEMPEST: "Eavesdropping On the Electromagnetic Emanations of Digital Equipment: The Laws of Canada, England and the United States." It includes numerous citations, including those mentioned by Joel and the one you found. He claims that the Van Eck article was "purposely misleading." We've put his article at: http://jya.com/tempest.htm Seline promised a later version of what he called a rough draft. Does anyone know of a successor to the 1989 article?
