DECnet-11/RT-11 came in tape and RX50 distributions. The last version
was Phase-III. Phase-IV was never produced. It really requires the XM
(and variants) monitor and it is BIG... And SLOW... And...

Subject: [HECnet] RT-11 DECnet?
Hello,
Now that I've gotten RT-11 rolling on the 11/23...is there
any way to get DECnet rolling on it? I can't find a tape
image anywhere. :(
If I'm going to get stuff copied to this...it's going to help
to have higher than 9600baud going for me. ;)
I suppose I could install the TCP/IP stuff but I've never
actually done that. Would TSX+ run on an 11/23?
Once my cleaning tapes arrive I'm going to install RSTS/E
from one of my DDS-3 tapes via SCSI drive. ;) (Here's hoping
the bootstrap on the SCSI controller does TMSCP bootstrap!)

The DEC calling standards and the design of DECnet do not limit us to
using only one language. Each system could use what ever is available
on that system (and what the user knows how to program in) and use
DECnet objects to pass information back and forth. A simple protocol
(if you will) could be spec'd out and implemented for any of the
languages. A common language could be used for the "glue". MACRO-11
might be fun - it could easily manage the differences between BASIC and
FORTRAN (and others) calling sequences (ie R5).

There are very few PDP-11s that won't kick the living snot
out of a Commodore 64, FYI.
But using FORTRAN, we could potentially use overlays and such.

My Pro-380 has built-in color (and graphics). Sound would be possible
using the TMS-11 - I have one of those as well...

I've yet to see a PDP-11 with builtin color graphics _and_ sound.
Me neither.
The 64 probably outsold all models of 11 taken together.
That's certainly possible, but one cannot argue that their
target markets were even remotely related. Or even aware of
each other's existence, for tha tmatter.
so it depends on your application and measurement I suppose.
We were talking about distributed math apps.
I'm told there were, probably third party, sound cards for
qbus. Has
anyone of you seen one or know more?
I haven't. I have a really neat Qbus card with a TMS9918
sprite-based video chip on it, though!

Have you guys ever banded together to solve a few math

this network?
I would be interested in learning how to do it.
That would be LOTS of fun. I'm in!
I'm even more interested if we could do it with (or
including) PDP-11s. Many of my PDP-11s have serious floating
point hardware.

10 and 20 are way too high. The problem is that the default cost for QNA
and UNA circuits is 3 (or 4 - I don't remember). Everybody connected to
Johnny's bridge therefore sees a cost of 3 to everybody else on the bridge,
even though that connection actually requires a hop over to Sweden (psilo)
and back again. Any two machines with Johnny's bridge would never use the
Multinet connection, even if it were a direct link between the two.

I guess that the "problem" here is that most people have local
machines on the same segent that is bridged.
Having a "to low" metric makes it impoissible to prefer a better path

This sounds strange but.....
Reliable - PTP link 10
Unreliable PTP link 20
Ethernet bridged 30
Would most likely render the optimal performance.
Why?
The ethernet bridge would, in my eyes be preferred to two or three reliable PTP links. The ethernet link is very fast for most people (unless they themself are on an ISP with severe limitations, in which case any other link will suffer equally), and has, with one or two exceptions proved very reliable.

Hi Bob,
In case an old version (19.28) is ok you can try the following.
I recently copied that version which compiles under 6.1 to a machine
with 8.4 and it works. As usual, if X is not available you get the
terminal version. At RULLFS:: you may find EMACS.ZIP and GNU_STARTUP.COM.
I zipped the contents of SYS$SYSDEVICE:[GNU].
In LOGIN.COM:
@SYS$COMMON:[SYS$STARTUP]GNU_STARTUP EMACS-19.28 NOLOGICALS,NOVERBOSE
which gives you
EMACS == "@SYS$SYSDEVICE:[GNU.LIB.EMACS.VMS]KEPTEDITOR EMACS"
In case something is missing, the V6.1 machine still boots :)

Of course not, but two hops via the bridge (as compared to one hop via
Multinet) does...
Bob
But 10 or 20 on SG1 for the multinet link to you would make you in control
over all of it. You could chise your bridge, my Multinet or the SG1 multinet.
I can give you login on STUPI...
