I've assembled some notes from old manuals and other sources
on the formats used for on-disk file systems through the
Seventh Edition:
http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html
Additional notes, comments on style, and whatnot are welcome.
(It may be sensible to send anything in the last two categories
directly to me, rather than to the whole list.)
Hi,
I successfully made SIMH VAX-11/780 emulator run 32V, 3BSD and 4.0BSD.
Details are on my web site (thogh rather tarse):

Enjoy!

At http://wwwlehre.ba-stuttgart.de/~helbig/os/v6/doc/index.html
you'll find the V6 assembler manual.

Hi all,
I just discovered this list & decided to join.
In August 2008 a thread was started by 'zmkm' where
he asked (among other things) for a "unix assembler
manual" by DMR. I could post a scan on line if
somebody is still interested. It's a 12 page text
and the CPU involved is -of course- DEC PDP-11.
Plse let me know.
Regards

Wow I'm surprised a few hours googleing about and I got it running....
I found this 'idle' emulator ("Incomplete Draft of a Lisa Emulator"
http://sourceforge.net/projects/idle-lisa-emu ), which can infact run
Xenix! It also says it can run the uniplus SYSV (so says the
readme)..
Searching around I found the following site:
http://unixsadm.blogspot.com/2007/12/xenix-blast-from-past-looking-back-at.…
which has Xenix 3.0 disk images in the DART format... which as luck
would have it idle cannot mount. However I found another lisa
emulator, lisaem ( http://www.sunder.net/ ) which has a tool to
convert the disks from DART to DC42 (disk copy 4.2).
So it was a simple matter of converting the disks
lisafsh-tool.exe "Xenix OS Boot Floppy"
quit
... etc etc...
Then firing up idle, setting the CPU to max speed, and booting up...
whenver I was going to answer a question I toggled it back to 5Mhz..
otherwise it would take FOREVER to boot... lol like the 'good old
days'.
Once the boot floppy had formatted the 5mb hard disk image, and
transfered on reboot I had to tell the bootloader to boot from the
profile disk..
pf(0,0)xenix
And away it went. After installing the OS & the C compiler I'm left
with 23 blocks free!.. which I guess for a 5mb disk, is pretty cool..
Anyways there are assorted Xenix PDF's which can be found here
http://www.tenox.tc/docs/
Namely these two for Apple Lisa Xenix..
http://www.tenox.tc/docs/apple_lisa_xenix_programmers_guide.pdfhttp://www.tenox.tc/docs/apple_lisa_xenix_programmers_reference.pdf
It's amazing that lisa emulators were sort of capable of running Lisa
Office System, now they can run the old unix stuff... it's still
impressive.
Hello from Italy!
I'm interested in Xenix copyright. Do someone of you know who exactly
owns Xenix? According to Wikipedia, Microsoft gave everything to SCO,
but did they gave also the copyright for the non-x86 versions?
I'm asking this because I'm interested in "saving" Xenix from fading
into the digital night. If everything belongs to SCO, then maybe an
"binary only, non-commercial hobbyst license" could *eventually* be
released, at least for older or non-x86 products
Best regards,
Lorenzo
PS: First mailing list post ever. I'm definitely a newbie, here :)
Yeah that's the extent of it. trust me I was shocked when I tried to
dd a Xenix install, and Qemu booted it right up. But without a C
compiler it's useless. I should add that the TCP/IP supported like 3
NIC's... so even *if* you could find it..... it'd be limited. You can
get the disk to work though.... But not under Qemu, Virtual PC and
VMWare can use it.
The 'issue' is that simply Xenix's method of detecting disk density
doesn't work under any emulator because while it's trying the wrong
thing it will 'work' when it shouldnt...
if you are trying to load a 3 1/5" high density disk, the device is
2/60
Low density is
2/36
so change the device for fd0 to be either.... or even symlink it.
For what it's worth, running it under Virtual PC is fast, however the
console is kind of screwed up.. Xenix uses a nonstandard screen mode
(well for virtual pc's bios that is).
I used to have Microsoft Word for Xenix... in the box and everything.
I'll be dammed if I know where it is. I wish I had managed to keep the
license cards.... :|
And no, outside of a picture from an ad talking about the PDP-11
version of Xenix, and one anicdote in USENET saying that any issues
they had were traced back to Microsoft additions to the system...
there is no trace of it.
But then who knows, maybe someone will post back with something.
