#2I do believe that MACRO in the slides refers to MACRO-11, a PDP assembler. Or maybe MACRO-32, for VAX. In either case, they have been compiling this "assembly" language for Alpha (and now I guess Itanium) since VMS has run on that architecture.

#3As an old time OpenVMS user (on VAX DECstations first and on AlphaServer later) I'm looking forward to this.
I doubt it will ever come even remotely close to a "mainstream" OS, but Alpha to x86 is a much better migration path than Alpha to Itanium.
And yes, there are still many OpenVMS installs out there in the wild, from airport logistics to assembly lines, so this may make sense from a financial standpoint (versus a complete software rewrite for Linux/AIX/whatever) - provided they can market it well enough to the old users.

Don't forget nuclear plants running PDP-11/VMS until 2050. http://www.theregister.co.uk/2013/06/19/nuke_plants_to_keep_...

Why? Not everything is free and open source. In fact, most of the operating systems used outside the "general-purpose" Linux realm are not (e.g. OS400, z/OS, z/TPF, AIX, Solaris, NonStop, QNX, vxWorks... even Windows Server).
That said, if you're really interested, HP offers free hobbyist licenses for non-commercial use of OpenVMS, with access to the OS and compilers and usable on real hardware or SIMH.

It's not entirely clear from the article, but I don't believe the PDP-11s are running VMS. As far as I know VMS has never been ported to the PDP-11.

#8ugh. i switched from vms to unix in '88 because the telnet in vms was crappy. other than the wonderful help system, I never found VMS attractive.

Yeah, they're likely running RT-11 or RSX-11.
I wonder if the hardware is original and they simply have plenty of spares, or if boards are rebuilt with discrete logic or FPGAs/CPLDs as they break down.

Could you please send me the link where it says that I can get the hobbyist license. I want to give it a try.
