MRC with the help of Stu Grosman did a phase 4 port to KS tops20. It
uses teh KMC/DUP, but has a limitation, as there was not enough memory
left, all buffers had to be in one page, the decnet MTU is not 576 but
376 or something like that. This does not matter unless you have two
interfaces and try to be a transit node. (it can be routein-iv).
Any idea where I can find this Phase IV port?
It speaks DDCMP on the CYNC interface, so anything that speaks DDCMP
can talk to it, DUP,DQ, DMC DMR ...

I ll see what I can do. Since a DMC/DMR does DDCMP itself, it shouldn t matter what OS is talking to it; if you get success with DECnet/RSX, I would expect it to work with DECnet/E as well.
Or, since it doesn t know sync from async, it will probably talk to a software
DDCMP implementation that uses a terminal interface.
I believe that it should also talk to an OS based DDCMP implementation which uses Async ports. If someone is willing to test this, I'll work on any kinks which may be found which might inhibit this.
I m trying to make some progress on that (using RSTS V10.1).
Let me know. I'm interested in using RSTS/E to link TOPS-20/KS.

Device XK0: does not interrupt - device disabled.
Probably a SIMH limitation. It s complaining about the KMC11.
This is true.
RSTS supports those only for use with the RJ2780 emulator; it doesn t use them with
DECnet.
The message comes from the hardware scan code, where it looks around the
bus looking for devices and makes them interrupt to learn what vector each
uses. For the KMC11, it does that by loading a short program into it. That
only works if the KMC emulation knows how to emulate a KMC well enough
to run that program. If it emulates a KMC only as a KMC/DUP pair that
speaks DDCMP, this won t work.
The KMC emulation could be extended to support this command/program, but since the only implementation of KMC functionality is as a KDP and the KDP wasn't supported on the OS (RSTS) which is observing the lacking of interrupting, then the status quo is probably best.

Apparently there are 2 user-mode routers.
Robert s is the first one I know of; inspired by that I started one in Python. Mine is still rather prototypical.

Subject: [HECnet] Getting reconnected...
Hi,
Now I'm back, I need to get reconnected to HECnet and get some routing sorted out. Multinet never worked, and I lost my fixed IP so I can't use the bridge. Is anyone able to offer some kind of IP tunnel, maybe VPN or something?
Also there was someone who was developing a Linux-based DECnet router, is that still going/viable?

Looks like there's no DMC on the PDP-10, no DMC OR KDP on the MicroVAX,
and no KDP on the VAX780.
However, the PDP-11 has the DUP. Looks like I can use that as the
go-between.
MRC with the help of Stu Grosman did a phase 4 port to KS tops20. It
uses teh KMC/DUP, but has a limitation, as there was not enough memory

That I can do. Once I figure out the TOPS-20 DECnet configuration. ;)
