Running 7.3 with a hobbyist license on SIMH, it took a lot of struggle to get DECWindows working. Two notable issues that don't seem to be documented:
1. Apparently you MUST install DECNET and configure it, even if you are going to use TCPIP as the transport for DECWindows. Nothing worked for me until I installed and configured DECNET. After that I could inhibit it from starting up with the "ignore" logical, and DECWindows worked fine over TCPIP, but without DECNET there were error messages saying that remote screens could not be opened because something was "unsupported" (%SYS-E-UNSUPPORTED)
2. When attempting to use XDM to activate a session from a remote host, it is impossible to actually log in unless the Xserver channel is zero (0). If you open X with a server number of 1 or higher, the login fails and you are returned to the authentication panel. This appears to happen because the SYS$SYSTEM:TCPIP$XDM_XSESSION.COM file assumes the server will always be zero.
Neither of these problems seem to apply to the Alpha version of VMS. Can anyone confirm that I've drawn the correct conclusions here?

That makes some sense if your primary workstation is running VMS. Mine runs Linux and I normally use either separate X servers on separate screens or something like Xnest or Xephyr to put a remote headless server into a window on my console. While I have real Alpha servers doing useful stuff, they are not located so I can conveniently use them as primary workstations. And I do run a lot of Linux-based stuff anyway.
The SIMH node, of course, has no graphical console of its own. While my real VAX experience never included DECWindows, I do find it more convenient now than just using a telnet session.
The bug that prevents XDM from handling any Xserver channel other than zero is real in 7.3. It was corrected in the 8.3 distribution for Alpha by patch 70-5-1747.
The script SYS$SYSTEM:XDM_XSESSION.COM from OpenVMS Alpha 8.3 can be copied over to OpenVMS VAX 7.3 and will partly fix the problem. There appear to be corresponding changes needed in a couple of other files, and I'm looking into it.

malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.
nmbonao December 08 2017 Is anybody knows OpenVMS 8.2 version downloadable version? or CD copy? Thank you very much

malmberg September 10 2017 https://sourceforge.net/p /vms-ports/wiki/VMSInstal lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?
DoeveR August 07 2017 Where can I find the write up on running VMS 6.1 using the simh emulator?
