To quote a few snippets :

Hm. I remember they had a SD boot track and then went to DD for
about 1MB/disk. I actually had one with the 8 inch 8MB HD - I
think the drive was a Shugart SA-400. Am I mis-remebering.
The first Xenix was a 1.x.x system - I even have an orignal
unopened package of one of those. When compiling you could
take the Unix codes with the system defs and tell it that it
was a CSRG system [that's the group that basically wrote BSD] and
it would compile cleanly.

When they went to the 3.x system it was sort of a hybrid with
many things from Unix System III - and I actually prefred the old
ones. Going to FreeBSD was like going 'back home' to the old
16 with the 1.x.x series.

and

Incidentally, my last Xenix system has only 8MBytes of ram. I think
16MBytes is the maximum that Xenix will address. My ODT 3.2v4.2 has
16MBytes. By contrast, my latest Ubuntu server has 4GigaBytes, where
the RAM cost about the same as what the 8MBytes cost my back in the
late 1980's.

My last remaining Xenix customer has a Wangtek DC-6150 tape drive
installed. It died perhaps 5 years ago and was not replaced. Instead,
I do nightly ftp backups over the network via TCP/IP to a Windoze
server. It was initially a problem because of Xenix TCP/IP inadequate
streams buffers problems. Rather than fix it on the Xenix end, I just
found a Windoze FTP client that would would retry until the buffers
cleared without timing out. Crude, but functional.

and also

* hd transplant to new hardware to continue to run xenix - if you can find a
486-100 or slower box that actully runs, reliably. (think 20 year old dried
out capacitors all out of spec making the circuit unstable at the very
least, if not a fire hazard! Not kidding! Seen it! Caps out of spec, so
voltage regulator circuit out of spec, cooked several parts of the board,
dried up stickers on components and on circuit traces caught fire!).

Interesting read if you're a geek - otherwise you'll fall asleep

By and by, these are all battle-hardened veterans
