As long as you don't reuse tainted Unix source code in your job, you will
be ok. There are so many books covering the Unix kernel: Lions, Bach,
Goodheart, Vahalia etc., that any concerns other than source code reuse
are negligible.
That's my feelings, anyway.

I think this relates to a spectre raised during the USL/BSDI wars.
Somebody suggested that anybody who had been exposed to AT&T source
code was ``tainted'' and could thus not legally develop competitive
systems. Somewhere I have a button that somebody brought back to me
from a USENIX, with the text ``mentally contaminated''.
Jesper, I don't think you need to worry about the problem. That kind
of restriction would be unenforceable.

Ken Wellsch has just uploaded a set of RX50 disk images containing
2.9BSD for the Pro 350 to the PUPS Archive. You can find them in
Distributions/ucb/2.9bsd4pro350-kcwellsc
He says:
I believe the RX50 is actually 80 tracks with 10 sectors per track,
thus yielding 800 blocks per disk. I think the first track is
reserved and thus Venix would not let me at it. Hopefully I have
not also lost additional information here too.
All the 34 disk images he sent in are 790 blocks long. Can anybody
tell us if we will need to recover track 0 to make these images useful?
At the very least, I've managed to find the pcreg.h file out of the
images (cat */*.rx50 | less -B), so I'm getting closer at recompiling
the 2.9/Pro kernel.
Cheers,
Warren

Tjo!
I have a question that I hope someone can help me with:
I'm thinking about getting myself a SCO Source license,
but I'm worried that I might get "tainted" by this
since my day job involves writing operating systems...
My employer would not appreciate getting sued because of
my hobbies...:-)
Has anyone done research about this aspect of the license?
My goals are twofold, running an older Unix version on my PDP-11's,
and of course I want to peruse the source of the classic versions.

Yeah, I'm interested. Can you write up what changes the linux port entailed???

I'd be happy to add any changes etc. into the Tools directory in the PUPS

It's about time Unix could read the Unix filesystem again :-)

I assume you mean the standalone V7 FS program rather than the kernel V7
FS support ?
The code was written in old C, and from a modern C programmers point of
view, rather sloppily. The warnings from the compiler were terrible, so I
added function prototypes, and made the code more ANSI C like. Then I got
rid of a few bugs, in one place I remember a character pointer being
assigned to a character.
I then typedef'd the data types so I could use int8, int16 and int32 in
the code to make it more portable. I stopped using structure overlays onto
the raw data as that is messy and is not good for (a) byte ordering and
(b) structure packing. It also allowed me to stop using the original V7
file headers which would have made a public release of the code
problematic.
The data is extracted from the raw block data by using special
architecturally neutral functions into locally held structures. That is a
particular win with the block number in three bytes trick that is used in
the inode.
It has been tested on i386/Linux with both glibc 1.0 and glibc 2.0 and
Alpha/Linux, no changes were needed.
Then I added a few new commands to let me look at the superblock and
bootblocks and a few other bits.
Then I released it.
I have just sent a copy of the program to Warren for inclusion in the PUPS
tools section. Its not very big.
Work is progressing on the V7 filesystem in the Linux kernel. Anyone who
wants the patches for that should send me an e-mail. I hope to get it into
the mainstream kernel in the Linux 2.3 series.
Jonathan
Hello All
A couple of weeks ago I hacked the program v7 from the bostic_tools to
work under all sorts of different Unix versions. It worked great and
allowed me to snoop around the V7 file system images from native Linux.
Anyone who wants a copy can send me an e-mail.
Anyway I had a few hours spare today, and decided to try adding the V7
filesystem to the Linux kernel. Results so far are encouraging:

I am using the loop block device to allow me to mount a file as a block
device, this saves me having to add a new partition to my disc. There
should be no reason why it won't work with a true disc partition. The V7
filesystem under Linux is read/write.
Anyone interested ?

No, it isn't. The 68000 is the quad pack, and is smaller than either

What is happening is that `make depend' invokes a script which finds
#includes in the source code, and builds a make dependency. However,
it's not very intelligent, and doesn't ignore:
#ifdef INET
#include <stuff>
when INET isn't defined. :-) This bites on several C files.
You just have to hand-prune the Makefile after make depend :-)
This is 2.9BSD, BTW, ignore if you're not using it.

Really? I have a DELQA sitting right in front of me, and when I look at
it, the large chip definitely says M68000. What could that be then?

Hate to disagree with you, Alison. The the DELQA really is 68000, take a
peek inside yourself. It is a dual-width too...
And the DEUNA is T-11, while the DELUA is 68000.
I have never bothered plugging in any DEUNAs myself, since DELUAs are
pretty common, and they atleast are pretty good. Never had any problems
with any of them.

Having two Qbus VAXen and several Qbus PDP-11s it's old turf. Also I worked
for DEC Engineering. that and I've done a lot of hardware level work on my
systems (repaired dead boards) so the designs are more familair.

I'm not sure if anyone mentioned this, but you can build a working 2.9
kernel (sans network) from the sources by just commenting out the references
to the networking include files. I think there is an offending reference in
syslocal.c also.

I have a DEQNA in front of me. There is a micro and that is a 8751 8bitter.
The big chip is a LSI ASIC that is a linked list DMA controller. No t-11.
The RQDXn(n={1,2,3} uses a t-11. The DELQA also does not use a T-11.

My local computer junk store has a VaxMate for sale. I'm not sure of the
model -- It has a DB-25 serial port, 10-base-2 ethernet, and a phone-jack
like printer port on the back, as well as an internal ST-225 hard drive
and a 5.25 inch floppy drive.
Anyway, when I turn it on it tries to boot up -- the graphical slider
thing on the screen gets about 90% of the way across and it displays the
number 83, which I assume is an eeror code since the number changes if you
boot it up with no keyboard. Anyone know what the 83 means or where I can
get a list of VaxMate error codes? Also, how intelligent is this machine
compared to a terminal? Will it actually run a Vax operating system or
does it need a server?

It's my understanding that 2.11 will run on F11 systems (pro350 and 11/23)
if properly configured but the only binaries loose are for split I&D.
So if properly configured you can get 2.11 to utilize the user/system
spaces.

Hi -

> The F11 does not do I&D split but does have user/system.
Correct. Some systems also have an 18bit only MMU which restricts
memory to 248kb max (others have a 22bit MMU and can physically
have more memory).
> It's my understanding that 2.11 will run on F11 systems (pro350 and 11/23)
> if properly configured but the only binaries loose are for split I&D.
Not likely. The kernel won't fit in 48kb that I know of. And there
will be no networking support since that requires supervisor mode
which non-split I/D systems don't have.
> So if properly configured you can get 2.11 to utilize the user/system spaces.
The skeleton of a Makefile for non-split a kernel exists but it
will take much work (it is essentially just a list of file that may
or may not be 100% current) to kick into shape. Also, remember that
programs like 'csh', 'vi' and so on are not only split I/D but
overlaid - they will not run on a non-split machine.

I'm going to give up as I seem to remember nothing anymore... sigh.
Allison also sent e-mail saying the DEQNA is not T-11 based. I guess
I'm thinking of an RQDX3. I've had no place to unpack my old iron in
over three years and certainly miss being able to pick up the part in
question before foaming at the mouth spouting nonsense. Many apologies
for suggesting such major inaccuracies. -- Ken
P.S. Allison describe the DEQNA as a state-driven device with PALs
(I think) and that "big F" may the the gate array also mentioned.

| Just for the sake of being picky... the DEQNA is based on an Intel
| microcontroller chip (something 8085-ish, I think). The ethernet chipset
| seems to be Fairchild (it's certainly got a big F on it.)
