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 March 24 2018 Probably. More people hang out on the comp.os.vms newsgroup.
vaxpert March 23 2018 I have a PE42A and other Alpha system stuff for sale. I'm in So California. Any interest out there?
goodbyespy February 27 2018 To Prohorenko. Please, visit group OpenVMS in the ok.ru
peteherrera February 24 2018 How much does it cost to buy a complete OpenVMS hardcopy documentation set of the latest version
prohorenko February 17 2018 Please help to obtain the license on OpenVMS
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?
