I mean a manual of a hardware or software system published before 2000 that is clear, interesting, insightful, engaging, or otherwise remarkable.<p>My favorite is the manual of COHERENT, a 1980s Unix System 7 clone for PCs:<p>http://www.nesssoftware.com/home/mwc/manual.php<p>The manual provided a comprehensive, clear, coherent (no pun intended) introduction to the system that made me grok Unix and its philosophy.
