Howdy,
A couple of DS2D 5.25 floppies landed on my desk from an AT&T Unix
PC/3B1. As I understand it, these are essentially UFS beasts. (I have
both 8 and 10 sector ones; neither appear to be bootable).
Are there any utilities out there available to digest these things?
If not, I suppose I can write one.
TIA,
Chuck

There is a load of images for the 3B1/Unix PC on Bitsavers, so I guess
someone read them in somehow:
http://bitsavers.trailing-edge.com/bits/ATT/unixPC
I _think_ I have heard of people using imgdisk to read and write that
format but I may be mistaken. Whatever it is, I hope it is known as I
have a (last I checked) working 3B1 that would like a full OS re-load
someday.

Oh, IMD handles it just fine. But I'm not interested in imaging the
disks, but rather extracting their contents (probably tar files).
Does NetBSD still support the PC7300 Unix UFS? Otherwise, I'll probably
end up rolling some code to get the contents.

I got both, an ATT/3B1 plus an Altos/586, this one orphaned of disks. I
would like to get (for the Altos) one fresh copy of Xenix but already
burned in floppies. I'd pay the shipment costs.

You can read them in with Dave Dunfield's ImageDisk tool -- and
apparently write them back out with the same tool.
You can also convert them to BIN images using ImageDisk and load them
into my 3B1 emulator:
