Ah, so that's your specification for an interesting system: weird with DECnet :-)
The AS/400 is a nice choice then . 48 bit architecture, was supposed to replace the S/38 (it's code compatible with it) and be a VAX killer at the same time.
Which obviously didn't work since every home has a VAX now as Johnny tells us repeatedly (or did I get something wrong ;-)
Anyway, I've configured the IP stack on one of them, 10 years ago and what I remember is this.
It follows the IBM way of doing things : nearly everything is menu driven. A system manager hardly ever types commands, he just fills in forms. The result ends up in a file which gets compiled or assembled with a bunch of others. AIX has something similar called SMIT (if my memry serves me well).
Well, I prefer to type my own commands and DCL scripts.
I'd like to get a small Unisys (n e Burroughs) A4 though.

Don't buy an AS400. Buy an RS/6000 - you can pick up a decent one for anywhere between 50GBP and 5000 GBP :D
The RS/6000 is just a AIX / random Unix box, whereas the AS/400 is WEIRD.
I like weird.

What do you mean by that?
Just that the discussions lately seems to have started assuming that everyone is running VMS. :-)
But I know that most people know that this is not true. I just felt like pointing it out. Not trying to offend anyone.

Joe, have a look at the simh site: there used to be a collection of tape images for TOPS 10 and 20.

Thanks guys... also checking out alt.sys.pdp10 - I'd gotten tapes at work a while back, then started messing with the Panda distribution. I may just try to bring it up from tape and try my luck once again.
Thanks again!

Nope. The information can be found at MIM::US:[DECNET], but I can tell you it is someone called Peter L thberg. Don't know if you know about him, though. But he knows pretty much all there is to know about PDP-10s.

Well, I had written that I considered 100VG a joke but decided not to send that :-). But - agree with you on that.

You're right, FDDI predated 100BaseT by a little. Not by a whole lot.
100BaseVG was always a joke.

Paul. In 1991 there was no fast ethernet as we know it today. Ethernet over glassfiber was proprietary and by and large restricted to 10 Mb/s.
The problems with the redesign had tot do with emulating FDDI's built in redundancy with ethernet.

Not true, not unless the implementation is crummy. Any halfway decent fast Ethernet host will run at wire speed, and the difference between 1500 and 4460 MTU isn't enough to amount to very much.

real network switches, and faster computer buses certainly helped there too.... Then there was that 'PC in the server room' thing that happened.... It was insane they'd sell 100Mbit cards on buses that could barely go above 10 or 33mbit.
2011/7/12 Kari Uusim ki <uusimaki at exdecfinland.org>
Yes, absolutely! The bandwith was 98% of the nominal value. Ethernet starts diminshing after 60%.
I did extensive testing of FDDI back in early -90's and put as much load on it as I could with about a dozen Alphas of the time and found out that it easily outperformed Ethernet.
FDDI gear were more expensive than Ethernet, but were more useful.
FDDI was really outperformed by GbE as the multiplexed 100Mbit/s wasn't available on so many platforms.

Off topic... I received a page, a few weeks prior, on a machine that was
not pinging. Turns out, it was one of a few old NOVA class boxes we
still have at my work, using FDDI for connectivity. Fortunately, a
disconnect / reconnect brought the ring back online; I was scared (and a
bit excited in a strange way) for a few moments that I was going to have
to do some extensive troubleshooting... FDDI still lives.

Remember what I wrote: this happened nearly two decades ago.____
IP is the protocol that survived and most people aren t even aware
what happened on local area networks before, say,1998.____
I worked for Fuji, photosensitive films, paper and offset printing
products.____
Most of the IT equipment was made by DEC: PDP-11 s (/44, /84, /93,
/24, /73 and /23), VAXes, an IBM mainframe (4081) and PC s.____
And lots of other gear, most of it in the research lab. A Motorola
box that ran Motorola Unix, and an RS/6000 under AIX 2.4 (?).____
The lingua franca was DECnet and LAT. No IP, though some PC s used
Novell and SNA over tokenring to make terminal emulation to the
mainframe possible.____
No IP. Sounds weird in today s world but DECnet eventually
connected everything. We got a **very** early Cisco router that did
level 1____
DECnet routing between the corporate ethernet and the finance dept
token ring. Another (DEC) box that routed DECnet over Datanet/1
(that s X25 in Europe IIRC). The mainframe used an SNA/DECnet
gateway (the big channel attached box).____
The RS/6000 and the Motorola systems also ran DECnet, endnode only.____
To make this a little interesting we ran the first FDDI network in
the Netherlands.____
Trouble shooting wasn t always easy, especially if the SNA/DECnet
gateway was involved!____
