Hi there,

as most of you already know, in November 2007 Joachim Schueth has
beaten a reconstruction of the Colossus code breaking machine using
the Ada programming language and a laptop running NetBSD.

Two interviews with Jo have been published, which might be of
interest to you:

NetBSD: <http://www.netbsd.org/gallery/schueth-interview.html>

Regards, Freddy
