<div><br>It definitely brings back the warmth memories when I was learning the Unix system in the University, and the legendary stories about its genius authors. <br> <br>
- "The first edition of Unix let programmers call 34 different low-level
routines built into the operating system. It's a testament to the
system's enduring nature that nearly all of these system calls are still
available—and still heavily used—on modern Unix and Linux systems four
decades on. "<br>
- The "first-edition Unix provided a remarkably powerful environment for
software development. Yet it contained just 4200 lines of code at its
heart and occupied a measly 16 KB of main memory when it ran."<br><br>Anyone still remember what's the gross line count, including the comments? I remember it was around 10,000, and I remember my prof quoting from the author, something like, 10,000 lines of code, that's about the maximum one can handle (memories each function and each line of code). <br>
<br>Was it, or was it about the <a href="http://www.lemis.com/grog/Documentation/Lions/"><em>A Commentary on the Unix Operating System</em></a> book that we learned, or neither?<br><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

</div>That was a great story. I was really interested in the idea of running<br>
the original Unix. That would be very cool, to run Unix 1.0 in some<br>
kind of emulator on my linux machine. Would that be possible?<br></blockquote><div><br>Yep, as in the article, <br><br>..." a copy of the <a href="http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1">first edition of Unix</a> [is] running on an emulated PDP-11/20."<br>
