Hmm, then that's not what I had. I could swear it didn't look like a
DEChub 900 though.

Same here.

Hardly. You just need the right connections. I was nearly 100% FDDI
on my home network in the mid-1990s...didn't take all that much money.
I didn't have much! ;)
Hell, when I got into FDDI in the early 2000s it was cheaper than
FastEthernet!

I was contemplating making my house 4-way redundant. MoCa. FE, FibreChannel, and FDDI. All to link to the basement.
If I had the cables I woulda done it, too...

Nope. I picked these up from Villanova University several years ago.
I was interviewing at a place recently and the subject of VAXen came up.
Interviewer: "I remember have an account on a pair of 4000/500s in a
cluster when I was at Villanova years ago."
Me: "Those machines are at my house now!"
Interviewer: "NO WAY!"
That's cool. :-)
It was. I don't remember why I don't work there though. I don't remember
exactly, but I seem to remember them not wanting to pay me enough. :)
I had quite a few machines up
here in your old place at one point. Don't worry, I'd only be after one
of them, and even that is low-priority at this point.
Going and rescuing all that stuff is something I really want to do one
day. Not anytime soon though. :(
Well, let me know when you're able to. Even if you can't move it all
down there, if you can just come up by car, you and I can head over
there with a truck, and the stuff (even yours) can sit here for awhile.
At least then it won't be in a barn, and won't be at risk in any way.
We could probably do it over a weekend trip, even on a liesurely schedule.
Yeah, that's definitely something we should do. There's no way I can
move the majority of that stuff down here. A lot of it I'll just never
run and so will likely put up to be given away.
Still, it won't be until at least early next year that I can even
consider this. Time and money are both really tight right now.

Sounds like a business opportunity, basically build an enclosure, get 5-6 consumer SSDs, RAID6 them, expose a SCSI/SAS/eSATA interface to the host. If one of the drives breaks/runs out of write cycles, the box indicates the slot and we provide a new SSD for the slot.
FreeBSD can do this easily enough.
In most cases (like my 4000/90, for example) that's way overkill. I just
want to be able to plug something in that would replace the internal
disks.
If I were doing this. I still think my 4000/90 is going to get hooked
up to a little MSA of some sort.
I was more thinking about selling this to "enterprise" users, not hobbyists :)
The device would be packaged as a black box with no configuration etc needed - it just looks like a SCSI drive to the bus.
It could provide more space, redundancy and speed for lower cost if built right..

No it is one frame, cannot be split. There is a half sized gs but it has its boards mounted horizontally

Hmmm. I wonder if those can be separated. I wonder if that also means
mine never would have worked. I don't remember having the bottom half.
That was also 10 years ago, so who knows, maybe I did have the whole
