No download available? I thought it'd be fun to mess around with but maybe it's for paying customers only.

The current x86 releases are in a rather raw state, e.g. you still have to cross compile x86 on an Itanium system.

Based on some claims I have seen elsewhere, they plan to release the V9.1 to non-commercial customers, which is meant to happen some time before the end of H1 of this year.

Who's using VMS these days? (not a dig, I'm wondering)

If you're dealing with anything Apple you're probably running macOS VMs on Apple hardware. At least for things like build servers, signing and such (CI/CD) when the projects start growing.

Parent comment ask about the OS descendant from VAX/VMS, that is being ported to x86. The subject of this thread.

What they did is more complex than that – the OS is 64-bit, but a lot of legacy apps use 32-bit pointers. All code runs in long mode, but to support those legacy apps, they put code and static data in first 4GB of the address space. 64-bit-clean applications can allocate data above the 4GB mark. 32-bit applications actually run in 64-bit mode, but they assume the top 32-bits of pointers have a fixed value, which mean…

Sounds a lot like Linux's X32 ABI, but motivated by compatibility rather than memory bloat - https://en.wikipedia.org/wiki/X32_ABI

So I’m totally unfamiliar with x32 but say that there is all kinds of 32bit apps that are just too big for a single person to port to 64bit (or simply too big too old) is this a silver bullet of being able to rebuild 32bit apps to run as 64bit ones?!

Seems like the kind of thing that OS X desperately needed...

Some satellite broadcasting platforms still use VMS for mixing the data carrousel with the mpeg transport streams. One of those services, millions use it everyday without knowing it.

Several pieces described in that patent still run on VMS in 2021

Right, I mistook the subject at large and misread VMS as VMs. Thanks!
