I got the replacement RTC chips this week and I have replaced the old one. After a little scare, now the 4000/90 is up and running, and keeping time and date.
Why the scare? Well. I ordered two chips. One of the ones I have got is faulty. Of course, the faulty one is the one I plugged in first... :)
Now I'm not sure about the state of the (by now) working chip. Buying to chinese traders via ebay has its risks :). On the other hand, I have improvised a testbench for the chips using an arduino, and I see the "damaged" ones _can_ keep the time-of-day, even if them are reporting as "faulty" (VRT bit in register D reads as zero).
I remember someone in the list was waiting for replacement for a DS1287A too. So just beware... I guess I have been lucky, 50% of my RTCs work :)
(If anyone wants the arduino sketch I'm using to test the chips, just say so).
Oh, now I need a disk for that machine. Right now it is running diskless as a satellite of my 4000/60, paging via ethernet (ouch!). I have some SCA-68-50 pin adapters for SCSI disks, and I have used those with success with 4GB drives, but I have read somewhere the vaxstation firmware can't handle disks bigger than that. Anyone knows if that is true? Can I plug in a generic, big SCSI disk and hope it will work?

Why Phase-III?
I think it was an implication for the time period he was looking for. Phase IV would be too new. And phase II do not have MOP, as far as I know.
I think Phase II does have MOP, and it looks like Phase I does, also. Look in the revision history of the MOP spec. While the latest (Phase IV, V3.0.0) spec does not show the dates of the versions, the previous one (Phase III, V2.1.0, in document AA-K178A-TK) does. It mentions V1.1 was dated January 1976 and V2.0.0 was March 1978. That fits the dates for Phase I and Phase II respectively, I believe. And the revision history mentions a change to a download protocol message between V1.1 and V2.0, implying that download was part of the 1/1976 edition of MOP.
Interesting. Definitely more than I know. I only saw the mention that MOP (or atleast downline loading) was added in phase III on the Wikipedie page about DECnet. Which is a rather shaky source...
Fixed.

More data: the Phase II MOP spec is here: http://bitsavers.trailing-edge.com/www.computer.museum.uq.edu.au/pdf/AA-D60… . Neat, I've never seen that document before...
(Phase II DAP, NSP, and DDCMP specs can also be found there)

I have a need to set up a PDP-11 running DECnet Phase-III,
preferably under RSX11M although I d take RSTS in a pinch. Not
RT-11. Have any of the install tapes or manuals been archived
online? Could anybody give me a hint or pointer?
I m not even sure exactly which version of RSX I m looking for.
I think Phase-III was first released around 1980-81, but I m not
even sure of that.
Thanks,

I can add others if you want. It's not that difficult.
Nice setup!
I use Cacti for monitoring; it too is a front end for RRDTool.

The problem there is that it's not that simple. It's not like an LDAP schema where the OIDs are right in the file. MIBs do all sorts of weird referential stuff. If you look at the cisco decnet mib file there aren't actually any OIDs in it.

Perhaps reading the MIB file might give you a clue to the oid? It's just a text file.

I'll have to take another look at that, didn't have much luck with that before.
I shouldn't need the MIB files if anyone actually knew the OIDs for what I need to fetch. That's how I do the tftp load thing. I don't have MIBs and don't want/need them. I just use the numeric OIDs.

Brian,
I *think* you have to load the Cisco Decnet MIB in to your local machine before snmpwalk will walk the Decnet portion. I found a MIB from Cisco but was unable to get it loaded on my Linux box, so I gave up. Not that I tried really hard, though.

Brian,
I just wanted to take a moment to say thank you for your hard work on this! The level of automation is incredible. Now we just have to get Peter on board:)
I second this. Thank you.
Thank you very much guys. This has been amazingly fun to do and quite a learning experience as well. I've done stuff I've never had to do before. I learned new things! :)
I think that you are now the perfect source of information to assist in the Hecnet mapping project - at least for the Cisco part.
I think he is as well.;)
That and I wrote the NCP based mapping code, so yeah, I might just be the right guy. :)
Looking at an snmpwalk of my router I'm just not seeing anything DECnet in any way. I think I'm going to have to resort to other options (all of which had issues of some sort, so we'll see what we come up with).
If anyone knows what I should be looking at in SNMP or what I need to do to be able to get DECnet info out of SNMP on a cisco, PLEASE LET ME KNOW. :)

Now all we need are charts. As one can NEVER have enough

What do you want charts of? I'm sure we can do that. :)
Per-tunnel traffic graphs could be fun. ;)
I would very much like to see these. I can likely already do them for
my own router; I'm running Cacti here. It is a very busy day here but I
might be able to do some stuff with that later to see how it goes. It'd
be looking at raw interface counters, but since those particular tunnels
only carry DECnet traffic that should be fine.
