Congratulations.

Thanks!

They used to send us christmas cards, now they send us fruit baskets.

I wish I was kidding.

Thank heaven for supportive donors. (we are a donor-funded 501(c)(3) nonprofit)

According to some sources on the internet then 6.2 was last.

Which is "sort of recent" in VAX world.

-a The last supported release on the 780 is 6.2, but I'd bet 7.3 would run.-a I base that on the fact that we ran 7.3 on our VAX-11/750 a few
years ago, and the last supported release for that is also 6.2.

I think the reason for the "last supported version" was that after that
DEC didn't have any running machines still around to test on, so they
couldn't say for sure it was fine. The oldest hardware that was still officially supported by the last release of VMS on VAX (V7.3) was the
86x0, if I remember right.

From memory, around 6.9 Kilowatts, 3 phase, for just the cpu
and no peripherals or storage etc. Would make a great lab heater.

Nothing of note internally is 3-phase; ours is running on
single-phase. A LOT of it. We can definitely tell when it's powered
up. :-)

We ran 7.3 on our 11/780-5 (a field upgraded 780) at Living Computers.

I don't think DEC/CPQ/HPE would have supported it.

VMS 7.1 SPD state:

<quote>
VMS V5.1 was the final version to support the
VAX-11/725.

OpenVMS VAX Version 6.2 was the final version to sup-
port the following:
VAX-11/730
VAX-11/750
VAX-11/751
VAX-11/780
VAX-11/782
VAX-11/785
</quote>

But if it runs then it runs.

And both 6.2 and 7.3 are generally out of support and has been
so for many years anyway.

Arne

Having been directly involved in researching and writing that
particular SPD text, the removal of VAX/VMS and OpenVMS VAX support for
those VAX systems was promulgated for two reasons:

1: no supported optical media devices on those VAX models, and no
InfoServer boot, and no media; no then-available TK50, 9 track magtape,
RC25, or other supported boot media at the Digital Equipment
Corporation (DEC) Software Distribution Center (SDC) / Software Supply Business (SSB),

2: no then-working VAX ystems to test and troubleshoot with, so
software support was going to be difficult or intractable for any platform-specific issues.

DEC could no longer source quantities of blank TK50 or older supported
media for those installs and upgrades.

Which meant those VAX systems need entirely-feasible but less than
easily supported shenanigans for performing OpenVMS VAX installations
and upgrades.

Nothing was done to OpenVMS VAX to prevent those VAX systems from
booting, and OpenVMS VAX V7.3 will boot and work just fine rCo assuming sufficient main memory available, and assuming a system manager / admin knowledgable in shuffing OpenVMS VAX installers around and with some
spare / swappable storage ardware.
