Ok, started playing with the SIMH vax8600 simulator and OpenVMS 7.3
Hobbyist.
I know they discontinued the hobbyist license program years ago, but does
one actually need a license to run it? Or would an older version like 5.x
or something be better? The OpenVMS community license is only for Alpha,
Itanium and some x86_64 architectures so I'm sure that wouldn't work in a
simulated VAX?

V5 introduced the license manager so anything after VMS V4.7 usually required a license
PAK.

Even VMS 4 has license requirements. They just aren't enforced so people
run it. The copyright hasn't run yet, though. Some people think it's ok,
others do not. Maybe it's fair use for research purposes, maybe not.
You can buy a PAK of ebay, or find bootleg PAKs online. That will let you
run the system. One can make a super weak case it's for education or
research purposes if the use is hobbiest in nature. Even that weak excuse
is out the window if you do anything commercial with it. Copyright law,
upon which licensing is based does have some exceptions, but they are quite
narrow and require competent legal advise to utilize. Especially since you
may be circumventing a protection device which has narrower exceptions than
plain fair use. The general consensus here and other dec related groups is
relying on such exceptions is too risky and it's morally wrong.
But it's rather akin to finding car keys and taking the car they fit for a
ride. Sure, the car's owner hasn't been by in a decade or more. But
ownership hasn't lapsed and you are driving soneone else's property. There
are exceptions here too: if you needed to move it to protect it, for
example, you could. But you couldn't drive it cross country to do that.
Again, the exceptions are quite narrow and require competent legal advice.
Also, this is at best a weak analogy.
So if you want to be completely legit, that's hard because you can't find
someone to take your money to transfer the license that backs the PAKs.
It's effectively abandonware. The law doesn't give you a pass on that.
Enforcement actions are always a risk if you go down this path. The works
are owned, and we even know who the owners are, so they don't qualify even
as orphan works. And that's not to mention the ethical aspect.

Ok, so there basically isn't a truly legit and ethical way to run it as a
hobbyist. I have seen the PAKs on ebay and was pondering one.
I have no plans for doing anything remotely commercial on any of the
machines I have, and I am not planning a server farm either.
Just a single machine for my own educational/fun purpose. But I totally

If you are willing to run it using a PAK you bought on eBay you would
be better off saving the money and just finding a copy of pakgen.c
and just making your own. To be honest, I seriously doubt the current
holder of the IP cares one way or the other. And as for commercial
use, what possible commercial use would there be for running anything
on a VAX.

There is not a legal way to run it unless you acquired a perpetual license to run it on
that system before DEC/Compaq/HP stopped selling such licenses.
Whether it is *moral* or *ethical* to run it is independent of whether it is *legal* to
run it, and a poor analogy such as one likening running it to stealing a car will not help

Yes. My analogy sucks, honestly.
Personally, I'm generally of the view people should make money off their
IP. But if they don't make it possible to pay, then it's more akin to
abandoned property after a while and ending sales means you don't want my
money when I use it.
There is an exception for copying books that are out of print. Libraries
can do that. While not spelled out in the exceptions, I tend to view
abandonware in a similar light: it should be ok to copy and use that out of
print software. Especially if you aren't using it for commercial gain.
Should be is a value judgement of what's fairest in general. It isn't a
legal value though... it would need to be litigated to know for sure and
it's the sort of thing that's hard to predict: would someone spend the
money to try to enforce something? If they don't is it worthless, so use
can't be theft since there is no value. Since it's unlikely to be
litigated, we won't know if this theory would hold true or the extent to
which it would apply. Rights are only rights to the extent they are
enforced or can be enforced at the end of the day. It's one thing to hope
you won't get caught when someone is showing an interest in enforcement,
but perhaps another if no one is. Or perhaps you owe obedience to that
right, regardless of what the current owners seem to think.
So i fell back on it's complicated, because it is and reasonable cases can
be made, etc. And I freely acknowledge this is just a personal view of
things and others may differ. I wish I'd selected a better analogy, though,
because as it was the implication of theft was rather more than I intended.

HP was running Pa/risc into the 2017's for code analysis, I have a

This is correct. HPE still owns the copyright on OpenVMS (all versions except x86_64 -
I'm not sure how that is handled since only VSI wrote it). VSI has all the sources
for all versions - VAX/Alpha/Itanium from HPE. They are allowed to publish updated
versions of any platform version, but choose not to for VAX because they don't see a
viable business reason - i.e. they won't make money off of it. Even doing the minimum
to get a new VAX version would cost more in expenses that they feel they can make back

I heard rumors of
such an effort going on for HPE OpenVMS VAX but I don't know what the progress is or
if it's still ongoing.

No, VMS Software has a license from HPE, they do not own
the copyrights to OpenVMS.
It is highly unlikely that they will be willing to free old VAX versions of the VMS
software.

Yes and no. You can install things if you have the kits. So mostly 3rd party software.
But if you were speaking of VSI supplied products (other than Open Source), yes that is
correct.
No updates, no separate license you can apply to your
existing VM to keep it going, just start over from scratch every year.
Technically, yes. While it probably violates the CLP (Community License Program)
Agreement, there is nothing that prevents you from starting up the new CLP VM, exporting
the license PAKs from it and putting them on your currently running VM. The con to this
is that they you miss the updates that were applied since the previous year. At some
point that might not be too bad, but currently, with updates happening every month to
compilers and other layered product it's a pain.
The other thing you can do is keep the system disk as pristine as possible and add a
second virtual disk with everything that you want to keep going from year to year -
account homes, software repositories, etc. Then just moving that disk over to the new one
when needed. You lose any customizations of the system disk, but you could write DCL
programs to make those modifications so they are transferable.

It is highly unlikely that they will be willing to free old VAX versions of the VMS
software.
They apparently are doing well enough to be a viable company supporting existing VMS
installations. They still even have Itanic & Alpha licenses
available.
but only to their updated versions...
As well as Community Edition licenses, although those
are only available on x86 now.

They were once amazingly great; now they are like Kodak and Polaroid,
making more from licensing the trademark than from merchandise.
For example, my first Android (that I bought just to play with and learn

There were several reasons for that.
Gary Kildall was not as obsessively competitive as BillG
Gary was a helluva nice guy.
Blowing off the original IBM meeting may have been the stupidest business
move of all time, but it was also one of the BRAVEST, to stand up and
thumb your nose at therm!
Novell was having ongoing legal battles with Microsoft over what they
could or could not use in their software. When Novell bought Digital
Research, I THINK that the only asset that they wanted was the copyright
of CP/M; they sold off and/or gave away everything other than that, which
they weren't stingy about. They wanted rights to it, not necessarily even
exclusive. If Microsoft EVER did another copyright infringement legal
action, . . .
"OK, you are angry that we copied some user intaface stuff, etc. But, we
now own rights to what YOU copied it from."
It was a "Get out of jail free card" for any similarities to MS-DOS.

Very interesting thread. I was kinda thinking too that someone running VMS
on a machine for hobby use would be too small of a potato to go after.
Incidentally, what would y'all value a MicroVAX 3100 at? I am looking at
one on eBay for $550 but am considering making a lower offer.
I have no details about it so don't know the amount of memory and such.

I have about five or six MicroVAX 3100s and a similar number of Vaxstation 3100s.
They were all given to me or rescued from being dumped so I didn't pay a penny
for any of them. Almost all of them have had problems with electrolytic
capacitors in the power supplies leaking. The nicad battery packs would also
have leaked if I hadn't removed them years ago.
If you are thinking of paying money for a Microvax 3100, I suggest you make
sure it hasn't already been damaged by leakage from capacitors or batteries
and if you do aquire it, take immediate steps to make sure it doesn't soon get
damaged by same.

I have no problem replacing caps in PSUs so if that's the only problem I'm
good. Although the battery damage you mention can be quite a bit trickier
(if at all possible) to fix.
Unfortunately many of the sellers on eBay don't really know, so it is part
of the risk one takes. So I am trying to make sure I pay a low but fair
price.

It depends on what the machine still has inside.
If you have to add disk and memory that will be expensive.
Also, if memory is missing, I’d be suspicious that the machine was faulty from the
beginning.
$550 seems like a lot for a machine, especially if it’s not running.
Just my opinion.
I got my 3100 about two years ago for $90. Just missing disc drives.

If you are patient, its likely a MicroVAX 3100 at a lower price will
eventually appear.
For disks I would suggest a SCSI2SD (now ZuluSCSI ?) or BlueSCSI
devices. You can partition one SD card into several drives. Using
industrial endurance SD cards is preferable, and slightly more
expensive, but in the sizes you are likely to need (~32 GB or less), it
shouldn't be too bad. SD card speed is not a factor.
Checking out the electrolytic capacitors at the onset is important. It
can be hard to diagnose and repair semiconductors in switching power
supplies damaged by a shorted capacitor.

Hi Jerry,
The ones I am seeing now range from a little over $500 up well over $1000.
But I will keep an eye on what pops up.
And perhaps some other opportunity will present itself too. Who knows. I
have a couple of MFM emulators for my PDPs
so a SCSI emulator would be neat. Those old drives tend to get pricey and
you never know how long they will last.

I still have a large supply of DEC SCSI drives, and some BA350’s shelves for them, but I
have switched my main VAXen over to SCSI-to-SD boards, though except for the VAXstation
4000/90 it makes more sense to use SIMH. I used to be dead against emulating hardware for
VMS, these days I would rather have a nice low-power and reliable solution.

I have a BlueSCSI in my HP logic analyser. It works pretty well but at one
time it was getting corrupted (I think it may be fixed now) and I have to
take the analyser apart to change the SD card.
There are adapters available that fit ribbon cable into the uSD slot on the
BlueSCSI and bring it out to an enclosed SD card slot giving you a lot more
control over how you make it accessible. Although this sounds a bad idea
for data integrity, it doesn't seem to have caused any extra problems.
I also use one on a 3D printer where the SD card slot is poorly mounted
and it's very easy to post a uSD card inside the printer.

though except for the VAXstation 4000/90 it makes more sense to use SIMH.
I used to be dead against emulating hardware for VMS, these days I would
rather have a nice low-power and reliable solution.

Hi Jerry,
The ones I am seeing now range from a little over $500 up well over
$1000.
But I will keep an eye on what pops up.
And perhaps some other opportunity will present itself too. Who knows. I
have a couple of MFM emulators for my PDPs
so a SCSI emulator would be neat. Those old drives tend to get pricey and
you never know how long they will last.

New subject: DEC H7821 / H7822 power supplies (was VAX and OpenVMS)
I have no problem replacing caps in PSUs so if that's the only problem I'm
good.
There are five specific 1800uF 25V (usually brown) capacitors that routinely
leak in H7821 and H7822 power supplies. They must be replaced with good
quality components suitably rated for use at the outputs of switch mode power
supplies. Unfortunately replacing the capacitors is the easy bit. The more
difficult bit is cleaning the mess from under the other components and
identifying which other components have been damaged. Some of the resistors
in series with temperature sensing thermistors have really oddball values and
their values may vary from one power supply to another. If the bands have
corroded off them, it can be a real guessing game trying to figure out what
resistance values to replace them with so that the power supply doesn't trip
all the time and so that the fans run when they are supposed to run and/or at
the right speed. (The fans can also seize up all on their own so check that
too.)
Dismantling the power supply for access to the solder side of the board is a
pain in the ass but you start to figure out how to do it without damaging
too much stuff after the third or fourth time doing it. (At least it is not
as bad as the H7816 in the DEC 3000/600. This one has a heatsink connected
to the live side of the mains for no particular reason that I can see other
than to make it difficult to do testing on it when it is running.)
Keeping the Microvax 3100 in its normal orientation helps reduce the amount of
leakage. Storing them on their front, rear, side or upside down makes it worse.
The machines can continue to work for some time with capacitors leaking unseen
inside them. The first thing to be noticed may be a strange smell...
The same power supplies are also used in DEC SCSI disk enclosures that use the
same case as the Microvax 3100 & Vaxstation 3100. They probably also appear
in the Decstation 5000, Infoservers and other similar stuff.

Peter Coghlan.

Hi Peter,
Great information. Thank you very much! If I get a 3100 I will make sure to
check things out before I power it on.
Thanks for pointing out the heatsink connected to mains. That could be a
painful discovery otherwise!

Where do you live? I'm located in Eurpe.
I'm considering to give one or more of my smaller VAXen away for free.
I was given a lot of hardware for free myself, and the time will come when
I shall hand over some items into the hands of someone else, especially
when he or she is younger than me ...

Well, I used to live in Sweden, but the last 31 years I have lived in the
US, in Georgia. That's where I live now.
I would love to take over one of your machines but I am thinking shipping
one to the US would cost quite a bit.
I do hope you find good homes for them when you are ready.

Ok, started playing with the SIMH vax8600 simulator
and OpenVMS 7.3
Hobbyist.
I know they discontinued the hobbyist license program years ago, but does
one actually need a license to run it?
Without valid license PAKs, you have a very
limited system. You have one login session on the console device (OPA0:). I forget, but
you may also be limited to the SYSTEM account. But maybe not. The VAX/VMS layered
products are not available. VAXclustering is not available, Volume Shadowing is not
available, etc. Languages are not available except for MACRO-32 which comes with the base
install and BLISS-32 which comes from the FREEWARE repositories. Getting software loaded
that doesn't come on a SimH mountable image is a challange. There is no networking
software (DECnet requires a PAK) unless you can beg Hunter Goatley at Process to give you
a VAX Hobbyist license for Multinet (or TPUware). Editors available are EDT, TPU and
TECO-32.
Process:
https://www.process.com/resources/openvms/ - VMS library links
https://www.process.com/resources/openvms/hobbyist.html - Process Hobbyist link
BLISS-32
https://www.digiater.com/openvms/freeware/v70/bliss/
Or would an older version like 5.x
or something be better?
As others have mentioned anything from 5.0 and up will
require the PAK licenses. You can run V4.7 and earlier and everything will work - except
networking. DECnet required a special install tape - which is available online, I
believe. There are also some V4.x distributions set up which had the DECnet license
installed. There was no DEC TCP/IP (Called UCX - Unix Connector Exchange I think) product
yet. You have to get it from Wollengong (TGV) or other third party sources. That will
require some research but I don't think any of them are available currently.
I would stick with the Hobbyist V7.3 software until you get more experience with OpenVMS.
The OpenVMS community license is only for Alpha,
Itanium and some x86_64 architectures so I'm sure that wouldn't work in a
simulated VAX?
No. First of all because the VSI Community License only works on
VSI branded OpenVMS distributions. None of the VSI PAKs will work on any HP supplied
software. Second is that it is x86_64 only. To get Alpha or Itanium PAKS you have to
join the OpenVMS Ambassador's Program.
