The Unix Time-Sharing System (1974) [pdf]

Gotta love this gem: "Perhaps the most important achievement of UNIX is to demonstrate that a powerful operating system for interactive use need not be expensive either in equipment or in human effort: UNIX can run on hardware costing as little as $40,000..."

&gt; We will not attempt any interpretation of these figures nor any comparison with other systems, but merely note that we are generally satisfied with the overall performance of the system.<p>Will write that in one of my upcoming research papers and see how it turns out.
