It's not usable yet, really. There are other Alpha emulators out there though that can be used free if you can accept limited features, slow speed etc.

TARDIS is an emulated MicroVAX3900 (VMS)
SIDRAT will be another one, clustered with TARDIS.
JUDOON when i get DECnet working will be an Ultrix (emulated again)
I have both physical platforms (PDP-11's, VAXen, Alpha's) and SimH
platforms. I mix and max as necessary.

Steve interesting story, and yes I'm not asking about those three

Let me put it to all of you this way. In the book
"Cuckoo's Egg" as
related by Cliff Stoll, his(?) VAXes were networked, via
Ethernet all
over the campus, (either running BSD or VMS), but they
were connected
to the Internet via leased lines.
And in a Doctor Who book, who's reasonably accurate on the
DEC based
side of things, and lousy on the desktop side, there are
PDP-11s and
possibly a few early Vaxes. and even an Eclipse.
What I am curious about is how the PDP-11s talked to DEC Net based
systems.
And which ones of the R* operating systems could be confused into
doing that, and in what ways.
Well, considering the fact that DECnet was born on the PDP-11, the
question should perhaps be rephrased as how non-PDP11
systems managed
to talk on DECnet. :-)
If the question is more on a practical note of how connections were
done, I think the original was over serial lines, but I might be
wrong. Multidrop as well as some high speed links were available in
Phase III, but ethernet only became an option with DECnet phase IV.
Not sure about the time frame for packet switched interfaces. They
certainly existed in Phase IV, but I don't know if they
were available
already in phase III.
The RTS-8 DECNET/8, which was mentioned earlier, talks
DECNET over a
serial line, using DDCMP.

Hello!
Okay.
Now the question that's worth a full Fizzbin. How many of us
here are running under emulation? This means either a SIMH
PDP11 or a E11. Or an appropriate Alpha that's done the same way.

"This signature fought the Time Wars, time and again."
When I joined DEC in 1980, Software Services was working on links out of
the building. PDP-11/70's running RSX-11M-PLUS used DMC-11's (later
DMR-11's) to connect to the outside. At first VAXWRK:: (VMS) was
connected to ASTRIX:: (RSX-11m-PLUS), and that was connected to the
other building that connected the campus to the outside. What they used
to connect the Parker Street Campus to other campuses I just don't
remember. Serial lines of some sort probably. The max speed was 56K.
SET HOST from Maynard, MA to Nashua, NH worked quite fast (for me
anyway) :-) Later, DMC's/DMR's were replaced by Ethernet cards
(DEUNA's et al).
RT-11 used mostly serial links at fairly low speeds. I want to say
somewhere between 1200 and 4800 baud - I don't really remember - it's
been too long.
At least one of the data centers in Parker Street used DECsystem-10's.
I have no idea how they were connected.

My current configuration:
CTAKAH is an emulated PDP-11/93 (E11/Linux)
COPOKA is an emulated PDP-11/94 (SimH/OpenVMS)
KOPOBA is an emulated AlphaServer DS20 (CHARON-AXP/Win64)
CTEPBA is a real AlphaServer DS10
BIGSYS is a real PDP-11/83

LEGATO is now emulated (has been for a year or so). It used to be a real
VAXstation-VLC, but the power costs for running even a VLC 24x7 started to
add up. An Intel Atom a) uses way less power, and b) is a much faster VAX
than any real VAX (sadly).
All the other machines here are "real", whenever they're turned on.

which there are DECnet implementations:
PDP-8: there's a DECnet implementation for OS/8.
PDP-10: TOPS-10, TOPS-20
PDP-11: RSTS/E, RSX-11/M/M+
VAX: VMS, Ultrix
The PDP-8 DECnet is actually for RTS-8, and not OS/8. However, it's
also only PHASE II, so I think we could rule that one out.
Oops! My mistake, thank you for the correction. I thought
it was for OS/8. I consider myself to be a PDP-8 aficionado,
but I've never seen the DECnet implementation
For PDP-11, I think that there was also some kind of DECnet
for RT-11.
DECnet/RT was phase III only. The RT-11 group acquired the sources from
the DECnet group to update it. Unfortunately, the project was cancelled
due to funding issues. Funding went to support the ports to the
Pro-series, and BASIC-PLUS to RT-11 from RSTS/E. I started in the RT-11
group (c 1983) just as they acquired it. I was hoping to start on the
project but that was not to be... The "kit" was available on magtape
and RX50's. It was huge! It really needed to be reworked to make use
of the extended memory environment, but that was never to be.
And you have IAS, as well as (probably) RSX-11D.
IAS-11 was based on RSX-11D. It had three environments:
multi-user/multitasking like RSX, real-time like RSX (actually more like
VMS in some ways too), and a timesharing scheduler. IAS implemented the
original version of DCL! It did look in some ways like VMS (because of
DCL and the three environments), but was more RSX like than anything
else. I worked in Software Services, in Maynard. My job was to support
RSX (all flavors), IAS, VMS, RT, and a number of layered products. The
largest customers for IAS were the various three-letter groups within
the US government. I supported two of them. We will leave the names
for a different time... :-)
I don't think there was a DECnet for RT-11, but I could be wrong.
Isn't IAS basically a chopped-down RSX?
Also, I wonder if VAXELN also had DECnet?
I'd imagine so, but I'm not certain. I'd guess yes because
the firmware for some of DEC's X terminals is based on
VAXELN, and early X implementations supported X over DECnet.
And isn't there some sort of Alpha in simh as well nowadays?
Barely, but yes. It's not really far along enough to be useful yet.

I have currently area 7 and 8 disabled on my bridge, just FYI. Seems to

Routing loops are bad. However, DECnet should normally be able to
resolve this, and get things right, as from a topology point of view,
DECnet can have multiple paths between nodes. Something is wrong, indeed...
The current list of the areas are on MIM::, which is shut down at the
moment, because of the issues with the computer hall. I hope to have the
machine back up and running soon...
Since GORVAX have an alternative connection, I'll keep it off at my end
for now, for trouble shooting. As things looks stable right now, it will
be interesting to turn area 7 back on and see what happens. Hold on to

There was. Megan Gentry commented several years ago on a thread we had,
that it was Phase III only. There was some initial plans and work to get
it to Phase IV, which she was involved in, but it was cancelled.
I don't have that code, though.
Oh my! I wonder who DOES have that code. We should see if we can
track it down.
Megan might. Probably one or two other people as well, but I have very few clues about RT-11...
Isn't IAS basically a chopped-down RSX?
No. IAS is a separate thread in the RSX family, but it's based on -11D,
as far as I understand. Seems to have had some really cool features, but
I've never actually used it, only read some manuals.
In some ways, it reminds me a lot of VMS. Much more of the same
attitudes like VMS. It implements all kind of stuff.
Oh ok. Sounds interesting. I had a manual set for RSX-11/M V4.0 for
my first -11 ages ago, and there was mention of IAS on just about every
page; apparently there was quite a bit of common code and/or design. I
didn't know it was that divergent. I've never messed with it, but now
I'm interested in finding it to explore.
Well, basically all userland is compatible between RSX and IAS. Internally, they differ a lot.
So, for manuals, all tools and the like were shared between RSX and IAS. Also layered products were shared.
Did you ever about some unused parameters in RSX, which as the PRIO parameter in a QIO$? Well, in IAS those are used...
Also, device drivers in IAS are actual, normal tasks, and not special pieces of code mapped and run in the context of the kernel.
IAS also works in three different "modes". If I remember it was something like real-time mode, program development/interactive and batch. Exactly what the differences were I'm not entirely sure, and one did not totally exclude the other.
You can read a little more at: http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CFEQFjA…

Isn't IAS basically a chopped-down RSX?
No. IAS is a separate thread in the RSX family, but it's based on -11D, as far as I understand. Seems to have had some really cool features, but I've never actually used it, only read some manuals.
In some ways, it reminds me a lot of VMS. Much more of the same attitudes like VMS. It implements all kind of stuff.
Also, I wonder if VAXELN also had DECnet?
I'd imagine so, but I'm not certain. I'd guess yes because the
firmware for some of DEC's X terminals is based on VAXELN, and early X
implementations supported X over DECnet.
Ah. Good point. I had forgotten about the X terminals.
And isn't there some sort of Alpha in simh as well nowadays?
Barely, but yes. It's not really far along enough to be useful yet.
Ok.

That really opens it up. ;) Simh emulates several platforms for which
there are DECnet implementations:
PDP-8: there's a DECnet implementation for OS/8.
PDP-10: TOPS-10, TOPS-20
PDP-11: RSTS/E, RSX-11/M/M+
VAX: VMS, Ultrix
The PDP-8 DECnet is actually for RTS-8, and not OS/8. However, it's also
only PHASE II, so I think we could rule that one out.
Oops! My mistake, thank you for the correction. I thought it was for
OS/8. I consider myself to be a PDP-8 aficionado, but I've never seen
the DECnet implementation
For PDP-11, I think that there was also some kind of DECnet for RT-11.
And you have IAS, as well as (probably) RSX-11D.
I don't think there was a DECnet for RT-11, but I could be wrong.

Hello!
Okay think of it this way: What operating systems can be connected,
and running on what (emulated) hardware?
Oh!
Do you also want to know versions of software? That can become a rather
complex list.
Not even sure anyone knows the full answer... There are/were DECnet
implementations for quite a few systems.

Various such lists have been started over time, but I don't think anybody
was willing to maintain them.
I agree that it's hard to figure out routing issues when the network
topology is unknown! A nice HECnet map would be worth its weight in gold
about now.
Area: 2
Name: Bob Armstrong
Location: Milpitas, CA (Western US)
Router: LEGATO:: - connected via bridge and Multinet Tunnels
I have a list which is pretty authoritative on who "owns" each area, but I have not kept any other information around, such as routers, geographical information, or anything similar.
Partly also because areas are not necessarily geographically coherent.
