... I've had quite a bit of luck mounting ancient Unix-and-friends filesystems
under Linux, albeit often read-only (not a problem if just salvaging data) and
sometimes with screwy file timestamps (possibly more critical in this case)
The real problem is the partition table, as these are often proprietary and
not very well documented, and Linux support for alien partition tables is a
bit sparse. You need to know where the filesystem starts and ends on the disk
in order to pull it out raw using 'dd' under Linux, and then mount the
resulting file image as a Xenix filesystem loop option.
For my Tek Unix box I ended up trawling the Tek's raw disk for fragments of
ASCII related to partition support. That gave me just enough data to
reverse-engineer the partition table format in the first few blocks of the
disk, and then get access to the filesystem sizes/offsets. For this case,
maybe someone has a suitable running Xenix install and can quote the format,
or has some useful paper documentation...

apparently it
has his Alfa Romeo motor club data on it (so it's clearly
+10yo :-)
I used to have one of those. I really miss that car.
Anyone know if the xenix fs can be mounted on
linux? (I doubt it, but
I thought I'd ask)
Don't quote me on this, but somewhere in the back of
my head I have a vague memory that Xenix used the same
file system layout as System V.
