It took HP until 2006 to replace the FDDI lan with ethernet technolgy. The fault tolerance of FDDI and the build quality of DEC's gigaswitch products.
The bandwidth of FDDI is a lot better than fast ethernet.

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.

Wow I haven't touched FDDI since ... 2001? There was some AT&T X11 NCR monster (something like a 32way pentium running SYSVr4) serving out all these tn3270 sessions to Windows NT 4.0 & Hummingbird eXceede.... Because AT&T was just plain weird with their mainframe... You couldn't get a SNA LU6.2 or 3270 session from them, but instead tn3270 that was even more so quirky regarding it's timing (for those who have used cisco routers for local ack to fake out the constant chatter in SNA)... Anyways the giant glorified PC was connected via FDDI to a cisco 7000. The one day it went down, I just broke the ring, and made it a single connection and it came up.
Ugh it was such a disaster, it was almost a happy day when they rolled in with 8 way PIII's ... to run the same tn3270 thing.
While on these grueling 3+ hour phone calls with AT&T they actually hired someone that would run ping....

I know there's a DECNet kit for Linux out there somewhere. Not sure about anything else. Nothing crops up on a quick Google search that isn't dated early 90s.

The hardware is generally pretty unique (save for it's similarity in patches to PPC Macs) - all IBM stuff generally is. The OS is proprietary but you can pick up media kits off eBay for not a lot. Also IBM documentation, certainly for RS/6000 / pSeries hardware and AIX, is readily available online without even needing a login.

"Never send a human to do a machine's job..."
That was a real surprise for me also. I assumed the only way to talk to IBM machines from the Digital world was the SNA Gateway. In early -90's when I was involved in making a IBM mainframe and the VMS environment (=DECnet) to communicate, there was the SNA Gateway in between.
When the communication was established, it worked fine. No problems that I ever heard of.
It interest me also to find a DECnet implementation for RS/6000. If anyone knows where to find one, please let me know.
I hate to admit (as an oath sworn DECcie) that I have a RS/6000 as a hobbyist system. In fact I have to admit that I do have most other unix platforms as well, because there are many interoperability things I've been exploring over time.

To stay on topic (somewhat): why no RS/6000 under AIX? That platform can run DECnet at least.
I'm not so sure about the AS/400, only had to deal with it once so far. IP, not a DECnet problem IIRC.

So with my long, non-billing Sunday afternoons giving me ideas, I've started to ponder procuring a midrange IBM box, say an AS/400.
How much do these things cost (like say a 93 vintage), weigh and dissipate heat? Also, how do you hook them up?
Sampsa
You don't have to find old tapes for getting the Pathworks for OpenVMS (Netware) as it is called. On the VAX SPL's from 1995 to September 1998 you'll find the kit.
If you don't have the necessary SPL's, I can extract the kit from my SPL.
The licenses are more complicated to find as Pathworks licenses has never been available for hobbyists.
IIRC the Pathworks Netware implementation was at Netware V3.12. Compaq did put an end to that story and the development didn't reach the Netware V4.* level.

For our mainframe access we used Novell's SAA gateway which... was
terrible, when Microsoft shipped SNA server 2.1 (was there a 1.0?!) we
RAN to that... And used it over IPX/SXP with people even using dialup
shiva's!
It wasn't until 95 with Microsoft including TCP/IP into the consumer OS
did it really start to matter.
Well from my POV anyways.

Don't buy an AS400. Buy an RS/6000 - you can pick up a decent one for anywhere between 50GBP and 5000 GBP :D
My personal home use favourites are the RS/6000 43P Model 150 (mini tower with PCI and a 640e Power PC), the 44P Model 170 (similar to 43P but POWER-III up to 450MHz) and the 7046-B50. All of them are workable in that they are quite, don't use MCA expansions and don't draw a fat lot of power. All of them will run AIX 5L too AFAIK which is relatively recent and well supported.
Nice thing about IBM too is the computer IS your OS license. Because no IBM RS/6000 (or any other system aside from x86 gear) is sold without an OS license, they don't bother printing them they just let anyone with hardware run the OS (support costs extra mind you). It's a nice touch and means AIX is very accessible as a Hobbyist. It's taken over my 'pet UNIX' slot from Solaris since Oracle castrated the free license.
Others mentioned DECNet will run on AIX, I suspect not on more modern versions but maybe 4.3.3 might run it?

Hello!
Mark those idiots at Oracle didn't kneecap the free license for
Solaris (also called SunOS, and a lot of nasty and disgusting words
which only a fellow use would understand,), they only threw more brick
walls to destroy to make use of it.
All that's needed besides a machine to operate it, is would you
believe, knowing the right people. It happens I have scads of those
copies staring at me right now.
I also have (she's currently asleep at the moment) a SPARC system
running Solaris 10 released in March of 2005.
Now what fool told you that? We can take that off list if you want.
Nice signature by the way, where did you find it?
And yes all of the above is indeed true. I spent most of my early
years arguing with systems like that. Also fighting with my ISP to get
better acceptance for non Windows systems other then the early efforts
of the Mac squad.
