Will it have DECnet access to another system (e.g., a SIMH VAX or linux-decnet)?<div><br></div><div>OpenVMS system can create and mount a Files-11 Level 1 disk volume, which can be read/written by RSX-11M/M-Plus and IAS. You could create a virtual Files-11 Level 1 volume with a SIMH VAX and then read it on a SIMH PDP-11. The same SIMH VAX can create a SIMH virtual ANSI-labelled tape, which can be read/written by those O/S's, and RSTS, I assume (I have never used RSTS). RT-11 disk volumes and DOS-11 tape volumes can be created with the OpenVMS EXCHANGE utility. Any of these can be to virtual devices that can be cross-mounted on various SIMH machines, as long as the O/S supports the volume format.</div><div><br></div><div>Of course, any systems that are DECnet'ed together can exchange files. I use linux-decnet on a CentOS (Red Hat) file server to store OpenVMS Backup save sets that are created using remote file access (FAL) directly from the Backup command. linux-decnet may not be available for very much longer -- the people that supported the DECnet code in the Linux kernel can no longer keep up with the latest versions of the kernel.<div><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Helvetica Neue'; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><div><div><div><div><div><div><div><div><div>Larry Baker</div><div>US Geological Survey</div><div>650-329-5608</div><div><a href="mailto:baker@usgs.gov">baker@usgs.gov</a></div></div></div></div></div></div></div></div></div></div></div></span> </div><br><div><div>On Apr 29, 2010, at 9:00 AM, <a href="mailto:simh-request@trailing-edge.com">simh-request@trailing-edge.com</a> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Helvetica Neue'; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="font-family: monospace; ">Message: 2<br>Date: Thu, 29 Apr 2010 14:54:50 +0800<br>From: Michael Richter <<a href="mailto:ttmrichter@gmail.com">ttmrichter@gmail.com</a>><br>Subject: [Simh] Making tape/disk images<br>To: simh <<a href="mailto:simh@trailing-edge.com">simh@trailing-edge.com</a>><br>Message-ID:<br><span class="Apple-tab-span" style="white-space: pre; "> </span><<a href="mailto:o2mee970b291004282354xbfdea62dwe8e2b8389f27a5b3@mail.gmail.com">o2mee970b291004282354xbfdea62dwe8e2b8389f27a5b3@mail.gmail.com</a>><br>Content-Type: text/plain; charset="utf-8"<br><br>Is there an easy way to take a bunch of files and turn them into either a<br>tape image or a disk image suited for attaching to a PDP-11 under SIMH?<br></span></span></blockquote></div><br></div></div></body></html>
