FRUGAL:: is a real VAXStation 4000/90A
MISER:: is a real Alphaserver 255/233
THRIFT:: is a real Linux box, and so is CHARY::
The above hosts are pretty much running 24/7 as (MISER and THRIFT at least) are used to do real and hobby work.)
CHEAP:: was a real VAXStation 4000/VLC, but it lost its power supply and I have not found a replacement. Would be much cheaper to run the VLC, and I am considering running FRUGAL:: under emulation at some point to save on the power bill.

Well done for that Tony, these walk through's look really simple to do on the surface but the reality is that there is significant uninteresting grunt work to get the information out there on a web page, despite all the blogging software tool help.
We could do with a few more of this kind of thing for the more esoteric operating systems and 'layered products'. The other thing that Steve Davidson has proven too me (by being very nice in pointing out how horrendous some of my VMS setup's have been) is that getting VMS installed with some layered products compared to having a properly configured VMS machine are very different points on a long line.
I noted from my previous post that Matt has a walk through of installing decnet on RSX: http://www.9track.net/pdp11/decnet4_netgen
which might be of interest to some.
I wouldn't have a clue how to do that!
Mark.

TARDIS is an emulated MicroVAX3900 (VMS)
SIDRAT will be another one, clustered with TARDIS.

I've never quite yet gotten around to setting up a HECnet connected emulator - maybe I have a psychological block, although the Raspberry Pi is almost there, it's more about finding it a home with suitable connectivity than any software related issues.
Mine are all Pi hosted. Tardis was running fine until 2 days ago, now it runs like a 2 legged dog.
As you guys probably know, my 2 always on nodes are both on SimH
running VAX/ VMS. One is on a HP Microserver, the other on a Raspberry
Pi.
It works effectively, I even discovered that the 'bridge' works on a
Linux box that also runs SimH seemingly fine.
I've only used OpenVMS 7.3 and RSX-11M+ 4.2 in DECnet (and HECnet) via
an emulator thus far because I don't have software kits for anything
else. Ultrix I'd like to at least boot for novelty factor (to extend
my claim of having used a vast array of brands of UNIX) and maybe even
a PDP version of UNIX Sys7 or something. The former DECnets, the
latter to my knowledge does not.

I've been interested in Matt's work on providing more platforms for SIMH in the VAX arena, including simulation of graphical displays, you can see his work to date here: http://www.9track.net/simh/video/#mono
Unfortunately this is currently windows-only, I'm not much for Windows as a server-hosting platform, so I'll have to wait patiently until he gets round to providing X support.
Does anyone run SIMH on Solaris? I've recently acquired a Sparcstation 5, and I guess it's the benchmark of a usable server-type platform for me to be able to run SIMH on it.
Regards, Mark.

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.

I have both physical platforms (PDP-11's, VAXen, Alpha's) and SimH
platforms. I mix and max as necessary.

Hello!
About all I found was those sources, on the iBib site. And for the
other OS, no hits so far on Google.
Steve interesting story, and yes I'm not asking about those three
letter agencies.
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.
