Hello, list,
I'm trying to remember what is the maximum number of area routers allowed in a DECNET Phase IV ethernet segment. Anyone of you have that information at hand?
Not aware of a hard limit, but there is a configurable limit on the host. Trying to recall details, but right now I can only spot a maximum routers parameter, which would imply that there is no difference between L1 and L2 routers.

Hello, list,
I'm trying to remember what is the maximum number of area routers allowed in a DECNET Phase IV ethernet segment. Anyone of you have that information at hand?
On other news, the old macbook I was using as home server has died, after years of service beyond the call of duty. I'm setting up my stuff using several smallish ARM computers. To be specific, now I'm running a cubietruck and and Odroid-C1 (and a raspberry Pi as router/firewall). I'm having trouble with the net connectivity, so some yo-yo disconnects from area 7 should be expected. Not so hard as last sunday, but I'm still doing quite a lot of reboots.
BTW, the SG1 multinet link seems to be down again (unless it is a problem in my side, which is completely possible).

Peter,
I have the drive imaged. Would you like me to send you a copy so you can help out? You know more about the disk structure than I do.
Still fighting with tape drive, though...

Had a chance to poke at this?
I've confirmed it can be imaged back to another drive. I also identified the grounding issue...it involves the harddrive of all things for some reason.

Drive either needs cleaned (need to find my cleaning tape) or it's shot. Wouldn't surprise me.

Getting that on there will be a bit of a challenge however.
The MRC's Panda distribution that runs under the KLH-10 emulator,
configure a tape drive to write to file. Make yourself a completek
boot/distribution tape. Write it to you SCSI tape drive, Johnny had a
program. Put the drive on the SC-40 and tell ot to boot from the tape.

Back to the manual!
I would do this with a copy of your boot-disk, as I don't remember how
the console processor file-system got there.. Think it's simular to
how it's done on a KS2020. (A file with the FE system and a pointer in
the home-block).

Found the tape drive!
Johnny, which tool were you referring to? C by chance? Only have a
SPARC for this.
Peter was referring to a bunch of tools that I wrote a *long* time ago, which allows me to copy files to/from physical tape drives under Unix.
They understand various tape image formats on disk, but it's easy to adopt to new variants as needed.
They are written in C, and are not complicated at all. I believe others have over the years written similar tools, so you should be able to find some somewhere.
Mine can be found at ftp://ftp.update.uu.se/pub/pdp11/tptools.tar. I hope they are in a somewhat understandable form. Documentation is close to non-existent, and they are not very forgiving to strange errors. :-)
