My first suggestion would be to try and dig up the original instructions for installing that particular OS on a real VAX 11/750. This may not have even been an OS that ran on a 11/750. If you can find how to install this OS on real hardware, then those original instructions will map to a simulator pretty easily. <o:p></o:p></span></a></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Have fun.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><span style='mso-list:Ignore'>-<span style='font:7.0pt "Times New Roman"'> </span></span></span><![endif]><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Mark<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-left:solid blue 1.5pt;padding:0in 0in 0in 4.0pt'><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Simh [mailto:simh-bounces@trailing-edge.com] <b>On Behalf Of </b>Ray Jewhurst<br><b>Sent:</b> Sunday, October 9, 2016 7:40 AM<br><b>To:</b> simh <simH@trailing-edge.com><br><b>Subject:</b> [Simh] Older Model VAX simulators, what can you do with them and how do they work?<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><div><div><p class=MsoNormal style='margin-bottom:12.0pt'>Hello everyone,<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>I have use the VAX 11/780-5 simulator for quite some time now and feel pretty comfortable with them so I thought I would play around with the other pre-MicroVAX simulators and have had no luck with them. I tried using the "recipes: from <a href="http://gunkies.org">gunkies.org</a> to set up some configurations and nothing works. (I know the 11/730 has some hardware differences, so that one is the least of my concerns.) Attempting to install 3BSD onto the 11/750 gives me a "0000010 HALT" and with the 8600 I can get all the way to the initial boot and I get a kernel panic. Now I will admit I haven't tried different deposits and frankly I don't understand very well how they work but I would really like to "try" these machines. Also on a similar note I think that we should either help to revive <a href="http://gunkies.org">gunkies.org</a> or find a new place to share our system "recipes" and configurations. For example, in the text file that comes with DOS-11 there are instructions that don't apply to that version of DOS and I would love to share a revised version of said instructions.<o:p></o:p></p></div><p class=MsoNormal>Thanks,<o:p></o:p></p></div><p class=MsoNormal>Ray<o:p></o:p></p></div></div></div></body></html>
