<p>The <b>3M computer</b> industrial goal was first proposed in the early 1980s by <a href="Raj_Reddy" title="Raj Reddy">Raj Reddy</a> and his colleagues at <a href="Carnegie_Mellon_University" title="Carnegie Mellon University">Carnegie Mellon University</a> (CMU) as a minimum specification for academic and technical <a href="Workstation" title="Workstation">workstations</a>.
