is nice, 74F currently, and we've got a big museum here
that's chock full of great hardware to work on. Just sayin'.. ;)
...and how much is online on HECnet? ;-)
All networkable machines at LSSM that have DECnet protocol stacks are
configured with Area 61 addresses, and are functionally "on HECnet"
whenever they're powered up. There's also our "always-on" node, an
Itanium2 running VMS, which provides network services internally but is
also visible to HECnet.
Many of the "bigger" DEC machines are DECnet-enabled:
VAX-11/750 (VMS)
VAX-6000 (VMS)
VAX-7000 (VMS)
VAX-8250 (VMS)
PDP-11/70 (with a second coming soon) (RSX and RSTS)
PDP-11/44 (RSTS)
PDP-11/53 (RSTS)
PDP-11/73 (RSX, RSTS, RT11, and 2.11BSD)
PDP-11/83 (RSX)
DEC3000-300, -600, -800 Alphas (VMS)
There are many other DEC machines...PDP-11/05, 11/34, 11/03, 11/23,
several PDP-8s, a PDP-14, over a hundred VAXen, about a hundred Alphas,
a few more VMS-capable HP Itanium2s, etc, but those aren't on exhibit,
or on HECnet. (I still need to wrap my head around DECnet-11M for the
non-Plus RSX systems.)
Also a Systems Concepts SC-40, though it's not yet addressed on
DECnet. Some of our folks need to bone up on TOPS-20 admin skills
before we turn the public loose on that, but it's up 24/7.
Our Symbolics XL-1201 Lisp Machine has DECnet installed, and our
gaggle of Symbolics 3600-series machines will too, once we restore them.
And we're working on getting 4DDN working on an SGI running IRIX. I
personally am also working on an Ultrix-32 DECnet-enabled system disk
for a MicroVAX-II, which will be coming up soon. And I have a DEPCA
board sitting here, which will be used to implement DECnet-DOS on one of
the IBM PC-AT machines upstairs on the second floor, which is mostly
microcomputers.
That's about 5% of our on-exhibit machines. The rest don't have
DECnet protocol stacks. (IBM mainframes and midrange systems, Crays,
Transputer systems, Data General/Varian/Burroughs/HP minis)
So yes, wink all you want, my friend; we long ago adopted the "go big
or go home" mentality, and the proof is in the running machines and the
visitors practically passing out as soon as they walk through the front
door. B-)
Working on an 11/83 for a friend tonight. Got RSX
installed. Working on
2.11BSD now. RT-11 and RSTS/E maybe later.
Very nice!
