(It didn’t have the /20 designation yet.) Was the machine bought and paid for by an individual? No. Did an individual have free access to do whatever they wanted with the machine on company or your own time? Not uncommon at all. We had a PDP-11 in 1970 it pretty well belonged to us. Management had no idea what it was. ;-)</div><div><br class=""><blockquote type="cite" class=""><font color="#000000" class=""><span style="caret-color: rgb(0, 0, 0);" class="">snip</span></font></blockquote><blockquote type="cite" class=""><div class=""><br class=""></div><div class="">Ken Thompson wrote the first "Unices" kernel on a cast-off PDP-7. While perhaps antiquated for 1969, is that really something that would have been accessible to an individual? 1st Edition was on a PDP-11/20; almost certainly out of the reach of individuals in the early 1970s. And the fact that they were getting *paid* to work on this is not a small point.</div><div class=""><br class=""></div><div class=""> - Dan C.</div><div class=""><br class=""></div><div class="gmail_quote"></div>
