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.

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.

How many of us here are running under emulation?
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.

MIM:: is an emulated PDP-11/74. PONDUS:: is a real PDP-11/93. MAGICA:: is a real PDP-11/70. GNAT:: is a real VAXstation 4000/90. KRILLE:: is a real VAX-8650. (PONDUS:: and GNAT:: are in my apartment, while the others are located at Update.)
Those are, I guess, the machines that I most often feel responsible for, even if there is a whole bunch of more machines that I guess I could claim responsibility for...

Nope, I was mistaken, Johnny corrected me. I was thinking of the
RTS/8 implementation. I'm sorry for my error.
