Hi, folks! It looks like you've got a fine site here.
I'm just a hobbyist and have no commercial or other need for a very reliable OpenVMS system and no need to support any specific VAX hardware; I'm just doing this for fun. I spent a most of three decades programming systems software under RSX-11M, VAX/VMS, and VAX/OpenVMS (all three primarily conceived and designed by the amazing Dave Cutler, who was also the principle designer of what evolved into Windows XP, and thus it is that it is Cutler to whom I bow four times a day).
Therefore, like many of you, I'd have to host OpenVMS on an emulator. The host platform I'd prefer using is Windows XP Pro (in part just to "keep it in the family", so to speak), but if there's a considerable advantage to using Linux (I've got a recent Red Hat release), I'd like to hear about that, too.
So I'd like to discuss the emulation options for a high-speed, high-end dual-core x86 hardware platform running XP (or Linux, if there's a clear advantage). SIMH has the virtue of being free, but if a couple of hundred bucks would buy me an easier-to-implement, prompt tech support-providing and less buggy solution, I'd definitely consider that first (more than that is too much).
I've seen the brief discussion here of SIMH and have visited simh.trailing-edge.com. It appears that SIMH does not appear to emulate RSX-11M: True? But it does emulate VAX/VMS, of course. How do you folks like the latest release?
Would it be able to support DECWindows, for example (or whatever HP's OpenVMS calls it)? Does SIMH lack support for valuable things a general software hobbyist like myself would expect to have? (I don't need networking, at least for now).
And what about CHARON? One post I found regarding CHARON said that it was free for non-commercial use, but I couldn't find anything else that said that. Does anyone know? From the marketing claims, if it were to be free for non-commercial use, it seems to me it would be ideal. If it's not free, anyone have any idea what they would charge for a hobbyist license?
From what I can tell eVax is not going to be at all suitable, since it's really not a VAX emulator. Or am I wrong about that?
So, I'd like to hear what you folks have to say on these questions. I hope there's enough activity that I won't have to wait long for a response...
SIMH will emulate PDP11 hardware but getting hold of a RSX11M kit may be a problem. I don't know what hobbyist arrangements the owner of RSX has if any. IIRC RSX was sold to Mentec.
People use SIMH for VAX/VMS and it works. You can have networking too.
For an Alphaserver you can use PersonalAlpha from the company formally known as SRI
or there is this one - somewhat more bleeding edge
(the main person behind the ES40 emulator is now involved in developing an emulator for commercial use. Watch for news on that).
You need to acquire a VMS distribution - you can order one from this site or borrow one. You get your hobbyist licences via this site.
DECwindows - I don't do GUI but I gather you can run a X Server on your laptop and display the DECwindows that way.

Simh does not emulate VMS or RSX. It emulates the hardware. It can be built and configured to emulate a couple of different VAX systems and several flavors of PDP-11. You can load VMS or RSX onto those emulated systems.
As stated by imiller, finding an RSX distribution may be difficult. Your best bet for VMS media is the hobbyist distribution.
Simh does not emulate the graphics hardware necessary to run a DECwindows server. You can, however, run client applications and send the display to any X-Windows server. If you have a linux system running X-Windows or load Cygwin and its X server you can use that to display your VMS X applications. You can even use XDMCP if you want but it may be difficult to get a usable keyboard mapping.
malmberg September 05 2020 VSI community non-commercial licenses for AXP/IA64 are available now.
malmberg September 05 2020 See the forum about licensing. Don't know if HPE hobby licenses still being issued. Commercial licenses still being sold.
silfox70 September 01 2020 I need the license for OpenVMS7.3. Where can I find them?
malmberg August 29 2020 Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
jiml July 11 2020 ssh to eisner is now giving (on linux) "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" , Has the server key in fact changed ? Of WHO can we ask that somewhere on the eisner webpage they
wyan May 06 2020 Turns out I had an account here, it still was set to my location a decade ago, so hey, I'm back after over a decade!
Hein April 21 2020 Hi all, haven't been here in years. Good to see it is all there still. I'm looking around at the forum to stop/start msipcap - 'could not be stopped' - for now. I'll shutdown FreeA
EstesDave January 09 2020 does anyone have or know of DRB32 manuals
