Greetings:
I've been playing with the mail system. Mailing to root brings up
can't find usr/lonex/xmail
This in itself is not a problem, as I only tried this to see what would
happen. However, I am curious as to what the lonex directory is (was).
It does not appear in my listing of the contents of tape 2.
Cheers!

Hi -

LONEX _was_ "Laboratory Office Network EXperiment" - a project
I worked on for many years (we started with V7) and which just ended
a couple or three years ago. We used 11/44s and 70s right up till
the end - by which point they were all running 2.11BSD. It was a
really neat system - had a common user namespace (YP before there was
YP;-)) amoungst all systems, a (for the time) spiffy text-mode menuing
interface to shield users from the fact it was Unix and so on.

The sendmail.cf as distributed in the 'GENERIC' system kit wasn't
cleaned up enough. That reference to a local mailer that I use
should have been removed.
Several things to note:
1) the sendmail.fc file does not exist - on purpose. You'll need to
perform step 2 and then do a "/usr/lib/sendmail -bz" to freeze
(pre-process for faster loading) the config file.
2) the sendmail.cf file is not suitable for use without customizing
(filling in the domain name, relay system, etc).
3) The aliases database (/usr/lib/aliases.{dir,pag}) are not present,
on purpose. You'll want to edit /usr/lib/aliases to suit local
tastes and then do "/usr/lib/sendmail -bi" to create the dbm
aliases database.

It's a directory I keep local works of art such as the local mailer
'xmail' which knew the details about routing mail within the "Office
Network" we ran.
> It does not appear in my listing of the contents of tape 2.
It shouldn't have been there at all.
You should have something like:
# Mlocal, P=/bin/mail, F=rlsDFMmn, S=10, R=20, A=mail -d $u
Mlocal, P=/usr/lonex/bin/xmail, F=lsSDFMmn, S=10, R=20, A=xmail -f $g $u
in sendmail.cf. Simply reverse the commented status of the two
lines to be:
Mlocal, P=/bin/mail, F=rlsDFMmn, S=10, R=20, A=mail -d $u
# Mlocal, P=/usr/lonex/bin/xmail, F=lsSDFMmn, S=10, R=20, A=xmail -f $g $u
And you'll be all set.

I just thought I'd share a few more of my experiences with you in the
hope that they may help someone out....
Over the weekend, I finally succeeded in ftping Tapes/Torsten/v7.gz -
version 7 as an RL02 image. (International ftp to the UK is terrible
at present!).
I have no RL02, so I booted the image on Bob Supnic's pdp11 emulator,
built a kernel to support both RL and RK05 drives and set about
transferring the vital parts of the system to an RK05 image, with the
kernel source, games and other non-essentials going to a second
image. The two RK05 images are pretty full!
I built kernels for the 11/40 (m40.o) and 11/34 (smch.o), to support
just the RK05, and added a second DL-11 as previously discussed on
this list.
Kermiting the root image to an RK05 on my 11/34 was no trouble. My
11/34 will booth the m40.o image just fine, but the smch.o image
caused much disk activity, but no console output. Version 7 thus can
be persuaded to work on an 11/34a, with a single RK05. The second DL11
is recognised and works as expected. Version 7 seems significantly
slower than version 6, when multi-user mode is entered.
Thus, I think I'd recommend version 6 for a small system ...
Cheers,
Bob.

As Warren says, you don't want to sync after an fsck run has made
changes to the disk. Simply turn off and reboot. One gotcha Warren
omitted was the process /etc/update, which is usually started at
boot-time from /etc/rc. This process does a sync every 30 secs
automatically. Before fscking a live filesystem, kill update first!
If fsck finds anything wrong, shutdown immediately without a sync.
Of course, fscking unmounted filesystems is far safer, but not always
possible for the root partition ...
Cheers,
Bob.

Hmm, while we're on the topic of fsck, the RL02 image of 7th Edition that was
given to me by Torsten Hippe had an fsck for v7 filesystems, but no source code.
Torsten did say that Johnny Billquist had the original tape, but Johnny says
he's not in a position to read the tape.
Anyway, does anybody have the source code to this or another v7 fsck? Any clues
as to who wrote it etc.?
Thanks,
Warren

What aborts? If by 'abort' you mean that the process of the system
coming up ceases and you get dropped into a single user shell then
that's exactly what should happen.

Ok - at that point if a manual "fsck /dev/rra0f" (and you should be
using the raw (rra) form of the device) works, then all you need to
do is hit a ^D and the system will finish coming up to a multi user
state.
Hmmm - I think we'll need some more information before hazarding a
guess as to what's not working right. The contents of /etc/fstab
and the current disklabel would be good starting points.

Well, yes, it will - by bypassing all filesystem checks. Usually
that'll work ok - but it's not something to do after a crash or
a power failure.

Hmmm - a bad block? Shouldn't be related to anything in ra0f unless
you've accidentally created overlapping partitions. If that were
the case though I'd expect massive and widespread corruption.
What was the error when the bad block was encountered? If this is
an MSCP disk you'll need to find the MicroPDP-11 Formatter and
see if it will revector the bad sector for you (BSD MSCP drivers
can not do this - probably just as well because I've heard it's
fiendishly difficult and if you get it wrong you've hosed your
drive).

I've recently been deluging the list with problems and obseervations
concerning the v6 kernel. Most recently, I discussed the putchar()
routine in /usr/sys/ken/prf.c, which prints messages only if the front
panel switches are set appropriately. I modified that routine by
commenting out an if, so the messages would always be sent to the
console regardless.
Having edited prf.c and rebuilt the kernel, I was suprised to find no
change in the behavior on bootup. Comparing the 'new' and 'old'
kernels (with cmp) showed them to be the same. The problem then is
that the kernel was not being rebuilt correctly.
Accordingly I removed all .o files, and the files /usr/sys/lib1 and
/usr/sys/lib2. I rebuilt again. The lib1 and lib2 files do not build
directly from the /usr/sys/run script, but rather use "ar r" to
replace the files in the libraries with the newly-built object
files. Thus I had to manually build the libraries. NOTE: it is
important to get the object files into the library in the correct
order -- I simply copied the order as for the distributed files...
I remember using tsort and lorder for Minix to determine library
component ordering, but I forget how that works ;)
Having rebuilt everything, not only did the messages print, but also
the second KL11 magically worked. Thus what I had been doing all along
was OK, but the kernel was not being properly built using all the new
object files.
Summary - to set up a second DL11 (configured as the first "local"
interface):
1) ed /usr/sys/dmr/kl.c
changing NKL11 to 2
2) modify /usr/sys/run to call mkconf with the additional
parameter:
1kl
3) Bob, so to speak, is your uncle.
Be sure everyhing is rebuilt.
I wonder if there is a bug in "ar r", whereby certain files fail to be
inserted into the library, so that old versions persist. Using the "ar
rv" verbose option may be wise ...
Hope this info is useful to those mad enough to want to use v6 ;)
Thanks for all your help.
Next project --- port the v7 shell to v6. Hmmmmmmmmm.
Bob

Greetings:
When I do a "reboot" the system declares that /dev/ra0f has an
undefined inconsistency (during fsck). It tells me to run fsck
manually, then aborts before starting the daemons.
I have dchecked, ichecked and fscked /dev/ra0f, and it seems to
be a happy partition.
ra0f starts on an even cylinder boundary. It has one file which
occupies some 54% of the space on it.
reboot -f brings everything up normally.
reboot worked at least twice without finding any faults prior to
this boo-boo. Looking through the man pages did not point me in
any yet untried direction. I did encounter a 'bad block' on /dev/ra0d,
the /usr partition, while doing a make clean in usr/src/sys, but this
turned out to be bogus, and did not involve ra0f. Coincidence or ?
All hints appreciated...

I've found out the reason for the non-printing printf's. The code in
prf.c only actually outputs to the console if the contents of the
switch register are non-zero... the code in question is the function
putchar() in /usr/sys/ken/prf.c
Still can't get the second DL11 going though ;)

OK, I'm still attempting kernel builds of v6 to support my 2nd DL11-W.
Thanks to everyone who's given me advice so far -- sadly it doesn't
work yet ...
I have two DL11-Ws, one as the console (CSR=0177560, VEC=0060), one as
the first local interface (CSR=0176500, VEC=0300). Under RT11, I'm
able to use both interfaces without trouble (using CONSOL.MAC to
switch from one to the other, since I haven't SYSGENed for
multi-terminal support). Thus I know the hardware works and is
correctly configured.
According to the docs in /usr/docs/start, all I need do to get support
for the second DL11-W is edit /usr/sys/dmt/kl.c to increase NKL11 from
1 to 2. (As far as the KL/DL driver is concerned the only difference
between the two types of interface is the base addresses, and it
happens to be configured so that the first KL11 other than the console
will have a CSR of 0176500, so I choose that one.) I can then rebuild
everything and run /usr/sys/conf/mkconf. At the mkconf prompt I enter
"rk", and "1kl", as stated in the docs. /usr/sys/conf/c.c and
/usr/sys/conf/l.s are built. Inspection of l.s suggests that the
correct interrupt vector of 300 is used ... Inspection of c.c implies
that the KL11 character devices will all have major device number
0. Looking at kl.c, it seems that:
c 0 0 Console 177560
c 0 1 1st KL11 176500
c 0 2 2nd KL11 176510
...
c 0 3 1st DL11 175610
c 0 4 2nd DL11 etc. 175620
I then finish building the kernel and boot from it --- no errors.
Creating the character devices as shown, I get:
echo fred >/dev/tty0 (the console) works fine
echo fred >/dev/tty1 (1st DL11) gives ...
/dev/tty1: cannot create
So I'm back to square one. As a test I set NKL11 and NDL11 to 4 and
ran mkconf with rk and 8kl. Still doesn't work. What am I doing wrong?
I'm out of ideas ...
Another interesting thing caught my eye as I was looking at the
docs. Apparently, the system should print out memory size as it
boots. Looking at /usr/sys/ken/main.c, I can see a whole bunch of
"printf"s which print out a copyright message and memory
details. Nothing is actually displayed on the console during boot!
_main is called from m40.s, and printf is a function defined within
the kernel code itself (of course ;)
Any ideas?
Cheers, Bob.

1. That little doc you sent out, Steven, made my day.
2. I got your note on the updates. Thanks again.
3. BSD2.11 is now running fine with a modified kernel. At this point
it is my pleasure to give you this Bug Report (or, what do I do now?)
a: The Netnix burps at link time. It says:
............. long list of modules...uipc_ustteq.o d.netnix.o
Undefined:
_arpresolve
_arpwhohas
_arpinput
It continues to build, but does issue a stop 1 (ignored) message.
At boot time netnix generates a bad magick number and fails to
load. I made the minimum number of modifications to the SYSYTEM
file to install the net.
Questions: Where do I look for the abovementioned symbols?
Do I have to run Netnix to go multi-user?
Unrelated questions: Will a DZV-11 (four line mux) work in place
of DZ-11? In my experience the Unibus and Q-Buss versions of this
board are 100% software compatible, but I'm failing to get a second
terminal going...
Now, the Real Doozie...
I have, to date, been unable to make any of the Games work. The message
is always "<name> not found". I tried worm, backgammon, wump, fortune,
others from the games directory. Binary dumps show what looks like valid
data in these files.
Spooky, huh?
The Saga Continues...

In my earlier I asked a question about DZ vs. DZV11 support. I am
glad to note that the distributed Kermit works quite happily on
/dev/tty0, the first line on the DZV-11.
I still can't log on to that line, but the night is young.

You have to enable a getty on the port before you can log in on it.
Edit /etc/ttys, adding if needed a tty00 line. There are numerous
examples in the file - it should be pretty easy to figure out what
to add or change. Then you need to tell 'init' about the change
by doing a "kill -HUP 1".
NOTE: ports are NOT bidirectional - if you're going to enable logins
on a line you won't be able to kermit _out_. And vice versa, if you're
going to kermit out you'll need to disable logins on that line. Yes
it'd be nice to have bidirectional ports - but someone keeps stealing
my copious supply of free time ;-)

I wager you forgot to select the 'NETHER' option in your kernel
config file. Setting NETHER to 1 brings in the ARP modules.

Hmmm, - the 'netbind' process gives an error about
undefined symbols. It sounds like that was ignored.
That's the signal not to run the kernel.
> At boot time netnix generates a bad magick number and fails to
> load. I made the minimum number of modifications to the SYSYTEM
That's because the netnix image was not successfully loaded - the
linker left the header set to something other than a valid a.out
header.
> Questions: Where do I look for the abovementioned symbols?
> Do I have to run Netnix to go multi-user?
In your kernel config file make sure that 'NETHER' is set to 1.
You could go multi user but you'd likely see a number of errors
as programs try to use sockets to communicate.
Best to have a valid kernel+netnix image set before going multiuser.

Firstly, thanks to Steven for a great email. Yes, add it to the docs NOW
before you forget! Secondly, most of what Steven said also applies to
2.9BSD, because it also uses overlays. However, v6 and v7 do not use
overlays, so you can't use these techniques with them.

I should have had another sentence in the paragraph above: the
kernel overlays must be between 48kb and 56kb. 56 is the max,
but the kernel also has a minimum BASE size of 48kb (but this is
all too easy to achieve ;-)).

That is most likely what happened - I'd made some changes to the
kernel just before creating the Rev 277 images (which is what was
entered into Warren's archive) and didn't double check that the
GENERIC kernel would build correctly.
I don't believe I've mentioned it on this mailing list yet but the
complete collection of 2.11BSD patches/updates are available via
anonymous FTP to the host FTP.IIPO.GTEGSC.COM in the directory
/pub/2.11BSD. There have been 4 updates released recently: 278 thru
281.
Cheers.
Steven

Hi Steve,
The most recent version (Rev 280) will build the GENERIC fine but previous ones
didn't. The makefile required tweaking. Maybe all he needs is the last few

Hi,
Well I havn't tried your mix but a DEQNA fits ok. What you need to do is do
a size on the unix file that has been generated and workout which overlays
are blowing the loader. If you add the size of the base code and any overlay
together they can't be more than 64k. Then just move things between overlays
and base until they work. You don't have to delete the modules that you don't
want, they don't add anything.
Good luck, it can be tricky but it does work after you have pushed a few modules
around.
Robin
Having given up trying to work out why v6 runs on my /34a, and v5
doesn't, I've turned my mind to the problem of trying to get a second
DL11 up and running so I can use a terminal as well as my trusty
teletype.
I've set up a second DL11 on CSR address 176500, vector 300. This
device is set for 96008N1, for what it's worth, and works just fine
under RT11.
I rebuilt the v6 kernel to enable a second DL11 interface. I have no
guide to the source, so all this is based on my guesswork. Needless to
say, it doesn't work, and I'm now out of ideas:
Modified /usr/sys/dmr/kl.c, the KL/DL-11 driver source. I'm assured
that the KL11 is an ancient serial interface ...
Extract from said file ...
/* base address */
#define KLADDR 0177560 /* console */
#define KLBASE 0176500 /* kl and dl11-a */
#define DLBASE 0175610 /* dl-e */
#define NKL11 1
#define NDL11 0
#define DSRDY 02
#define RDRENB 01
I simply changed the number of KL11's from one to two:
#define NKL11 2
A further comment in the code says:
* set up minor 0 to address KLADDR
* set up minor 1 thru NKL11-1 to address from KLBASE
* set up minor NKL11 on to addresss from DLBASE
What this is saying is that minor 0 will be 0177560 (my console, which
works fine), minor 1 will be 0176500 (which should be my second
DL11). The code even does what the comment says ... ;)
So I rebuild the kernel, reboot.
Now, /etc/mknod /dev/tty1 c 0 1
makes the device, and
echo Hi >/dev/tty1
gives:
/dev/tty1: cannot create
What is up? Naturally if I set up a login for that terminal by editing
/etc/ttys, the process loops and causes a great deal of disk
thrashing. Something is clearly up with the configuration of the
device drivers here ...
Does anyone know how I'm supposed to do this properly? Advice and
guidance would be much appreciated ...
*********************************************************************
On a completely different note, would someone be so kind as to give me
the source for a very small Bourne shell and accompanying utilities
(/bin/test etc...) that I could port to v6 without too much difficulty?

Bob.

That is strange. The GENERIC kernel should build with no problems -
efforts were made to keep the Make.* files in /sys/conf in sync with
the GENERIC system.
Alas, it sounds like I didn't keep the template Makefiles current
enough ;-(
I doubt there are any books out there that know anything about
overlays - it's a a lost art from what I've seen.
I'll follow up with a mini tutorial on how to build a kernel. One
note for now: it is 99.999% certain that after configuring a
non-GENERIC kernel you will get a size error from the linker and you
will have to adjust the overlay layout in your kernel build directory.

Greetings:
All I did was add 1 DEQNA, 3 DLV's (total 4), 1 DLV. Has anyone tried
this? The Makefile proceeds without errors until the final (massive)
link run. Then it says
too big for type 431
and exits code 2.
I tried playing with Makefile, deleted some modules, like the rk, which
I do not have, and moved a couple around. Same result.
Obviously I'm new at this. Any assistance appreciated.

Having got past the emulator stage now (and having had my RK05 fitted
with new heads after a _spectacular_ crash), I've been setting to the
task of resurecting UNIX on the system.
Thanks to John Wilson's excellent KSERVE Kermit server for RT11 I've
been able to transfer v5 and v6 disk images to RK05.
v6 boots just fine, and runs without any real drama. v5, much to my
suprise, does not ...
First off, my hardware is:
11/34a (no fpp, no cache)
124K word (248Kb) MOS
2 x DL11-W
RX11
RK11D
1 x RK05
1 x RX01
v5 boots to the '@' prompt. Entering the kernel name at this prompt
(this is the kernel for the RK05, obviously), causes a great deal of
disk activity - far more than for v6, in fact. The disk activity
stops, but no login prompt is presented. The processor is not halted,
but is executing a relatively tight loop.
Under emulation (using Bob Supnic's pdp11 emulator), v6 ran fine, but
v5 caused TRAPS every so often. It occurs to me that the behaviour
I've seen on the real 11/34 corresponds to a trap observed using the
emulator. The emulator can be 'continued' after a trap and all is
well. Since the 11/34 doesn't actually halt, but merely sits in a
tight loop, I can't see how to proceed.
Question is, is what I'm seeing a kernel panic? Since nothing is
output to the tty, after the '@' prompt, it may be that the kernel
doesn't like the look of my DL11 configuration? Alternatively,
everything may be AOK, and running, except that no login prompt is
produced on the tty.
Interestingly UNIX causes a UNIBUS reset as it finishes booting. This
is evidenced by the clattering of the RX01.
Naturally it's not necessary for me to get v5 going, since v6 is fine,
but it would be extremely interesting to find out what is going on. v7
seems to give a great deal of TRAPs on the emualtor, so maybe that
would not like the real hardware either judging from current
observations.
What do people think about this?
Cheers,
Bob.

First off, thanks to all the people who gave me info for the rk? and
rrk? devices. That now works. I now come to the question of tty
devices.
On v5 and v6, the single terminal device which is set up is /dev/tty8
(c 0 0). This suggests to me that the system is build with a DZ11 (or
similar) as tty0 to tty7. Am I correct in this assumption?
My system has a pair of DL11s, and one of them works happily as
tty8. I'd like to get the second interface up and running. I also have
a DZ11, if that is any help. (The second DL11 is set up at present and
works with RT11 using the CONSOL.MAC mechanism to switch ttys. I can't
remember the CSR/VEC, but it is the RT11 default for a second DL11).
Question is:
------------
o What is the device numbering (major/minor) for a second DL11? (and
what CSR/VEC should it have?)? Or need I rebuild the system for
support of a second DL11?
o Second, is the DZ11 supported by default, and, if so, what CSR/VEC

While I was hacking away at a tcsh-like shell for Minix (a 7th Edition clone
for IBM ATs), I came up with this truly bizarre method of job control. It
even works!
Warren
Seventh Edition Job Control
Job control can be achieved under early versions of Unix, such as
Seventh Edition, by using the ptrace(2) system call in a manner not
intended by its designers.
Ptrace() was designed to allow a parent process to trace the excution
of a child process, stopping the child under certain conditions,
examining or modifying the contents of the child's memory, and
restarting the child. The stopping/restarting abilities of ptrace()
can be used to provide job control.
To permit a child process to be stopped, it must inform the parent
that it wants its execution to be traced, which it does by
ptrace(0,0,0,0). Fortunately, this can be done after the fork()
and before the exec() in the shell.
When a traced process is executing, it is stopped under the following
conditions:
+ the process receives a signal, or
+ the process exec()s
If the shell is wait()ing on the child, it will be informed that
the child has stopped, and can determine the signal that caused
the process to stop (SIGTRAP in the case that the process exec()d).
It is then able, using ptrace() with various arguments, to terminate
or restart the process. At the same time, the shell can also deliver
the signal to the restarted process, or not deliver the signal (see
the manual for ptrace(2)).
Seventh Edition job control, thus, is not so much a matter of stopping
a process when requested to by the user, as ensuring that the
process is always restarted, except when the user wants it to stop.
Restarting stopped processes is straightforward. Stopping a running
foreground process, however, is difficult, as there is no terminal
key that, when pressed, will inform the shell to stop the process;
indeed, the shell is most likely blocked wait()ing for the process
to terminate.
Two keys that do affect the execution of a foreground process are
`int' (usually ^C or DEL), which sends a SIGINT to the process,
and `quit' (usually ^\), which sends a SIGQUIT to the process. The
latter cannot be caught or ignored by the process, and the delivery
of SIGQUIT causes the process to terminate, usually with a core
dump. However, when a process is being traced, pending signals are
not delivered; instead, the process is stopped, and the parent
informed about the pending signal. The parent can choose to terminate
or restart the process, delivering or ignoring the signal as
described above.
Therefore, with ^C being frequently used, and ^\ rarely used, it
is possible to reinterpret the meaning of ^\ and SIGQUIT to mean
``stop the process''. The SIGQUIT from ^\ is never delivered by
the shell, but all other signals (including the SIGINT from ^C)
are delivered. Users can then re-bind the `quit' key with stty(1)
to be the more traditional `stop' key, ^Z.
All,
It looks like this old PDP unix mailing list is going well, from all
the questions & answers going past. Does anybody know of software to archive,
catalogue, search and retrieve mail archives via the Web?
My v7 a.out simulator is now working pretty well. I still can't run
/usr/games/chess, but I can compile a kernel from scratch using v7 cc,
and I can also compile the /usr/bin programs using v7 cc. The latest version
is available at ftp://minnie.cs.adfa.oz.au/apout2.1beta.tar.gz
P.S If you know of anybody else who would like to join the mailing list,
please let them know about it. The more people we have helping each other
out, the better.
Cheers,
Warren

All,
I am still bashing away at my v7 a.out simulator, available at
ftp://minnie.cs.adfa.oz.au/apout_2.1.tar.gz. I'm having a *$(&(#(@ of a time
getting it to work 100% correctly.
At the moment, I can compile 30 to 40% of the programs in /usr/src/cmd. It
seems that the assember isn't being simulated correctly. Nearly all the
other programs work fine.
Does anybody have any PDP-11 asm programs (preferably v7 Unix .s files)
that give the user mode a damn good flogging, and catch instructions and
addressing modes that are not working correctly :-)
Thanks all,

Ah yes, the classic Catch-22...

Greetings:
Woe is me.
I have been trying to resurrect Unix (BSD) on my venerable PDP-11/73.
It had an RL02, which has gone west.
It is running RT-11/TSX off an RD-54, and I would much like to run
BSD2.11 instead, for several reasons.
Now, I have several components of 2.11, and I'm trying to build a
bootable TK50 tape to install from. The problem is that I cannot
seem to assemble the tape files onto the tape using RT-11. It has
no 'dd' facility. At least, I thought it did, but every left-handed
syntax variation I have tried has resulted in "You can't do that"
-type errors, so I have given up.
This is really a simple problem. I would steal another RL02 if I could
build the tape from BSD2.9, but it doesn't support MSCP. So what I
need is either:
1. Someone who knows the secret to doing an addressable variable-
block-length transfer to a TMSCP device with RT-11; or
2. A bootable RL02 image of 2.11, wwhich would be a feat; or
3.A bootable RD5X image of same; or
4.A TK50, preferably the distribution tape.
(Yes, I put eggs in my beer).
All leads appreciated. I *do* have surplus Q-bus hardware (except
for RL02 drives).
Cheers!

Hmmm - does RT-11 have the ability/utilities to write 512 byte
records "bits as is" to tape? No labeling, no nothing.

Can you, using RT-11 do the equivalent of:
cat mtboot mtboot boot > file
dd if=file of=tapedrive bs=512
Basically what you want to do is have two copies of the tapeboot
block followed immediately by the boot program written to tape
using 512 byte records. Perhaps catenating the data together into
1 temp file first would help and then write that file out all at
one time.
Once you have that data on tape you have a bootable TK50. The
other images (mkfs, restor, etc) can be put on separate tapes if
need be and loaded one at a time.
That will require some interpolation of the setup/installation
documents but it shouldn't be too hard to figure out.

Bletch (to eggs in beer) ;-)
TK50 tapes are excrutiatingly (sp) time consuming to write - I'm not
sure where the problem is (other than the TK50 being about as smart
and fast as a rock). Reading them isn't too bad, but to write a full
2.11 kit on TK50 took around 7 hours the last time I did it on a 11/73.

First, I want to complement you on the excellent docs for 2.11BSD.
Second, I want to flame the people at DEC who decided that the
TK-50 MUST have a directory of some sort, and that various commands
which will work with other mag-tape devices will NOT work on the
TK-50 (under RT-11).
I am now going to plan B. I am going to scrounge up a proper reel-
to -reel magtape.
Anybody know where I can find one ? :=)

Agreed, they are excellent, Steven did a wonderful job of continuing and
enhancing the docs that were completed for 2.10. They originally enabled
me to do a complete install, never having done one for anything other than
RSX and with zero UNIX experience. SO again, well done Steven.

Can you not write to the TK50 using system calls?. What you need to do is to
write a utility that does "raw" byte by byte writes to the tape. I can't
believe that this can't be done. If this can be done then images could be
written to the tape exactly as they appear on a standard 2.11 distribution
which could help you out.
Failing that, where are you?. Could one of the people close by who have 2.11
cut you a TK50?.
Cheers
Robin

Greetings:
I'm getting there. Now that I have a working(??) drive, more trouble.
The file size/# of records/block sizea aren't matching.
bytes, 512 -byte
Tape file Docs- #records, size PC RT11disk blocks
0 mtboot 1 512 512 1
boot 14 512 32462 64
1 disklabel * 23@ 512 or 1024 36191 71
2 mkfs 28 1024 31727 62
3 restor 27 1024 34066 67
4 icheck 26 1024 31356 62
* disklabel was quoted as two different bs in two different places.
I really think that my gunzipping is kosher- I do it in the PC
prior to ethernet-ing it to the PDP with no errors, and in fact
I unzipped one file on my unix host and beamed it down. It was the
same.
Anyway boot is too big or restor is to small, or something. Any ideas
whatis going on here?
Merry Christmas!

I'm not sure what you mean by "not matching" - the sizes you list
below are correct. 'boot' is 32462 bytes, 'disklabel' is 36191 bytes,
'mkfs' is indeed 31727, and so on.

ARRGH! That's a typo in the setup documents. Sorry 'bout that. I'll
updated the master copies and post a patch in comp.bugs.2bsd soon.
ALL of the executable programs (disklabel, icheck, mkfs, restor)
must be blocked at 1024 bytes per record on the tape.
> I really think that my gunzipping is kosher- I do it in the PC
Yep - it looks like the gunzip went ok - the byte sizes look correct.
> Anyway boot is too big or restor is to small, or something. Any ideas
> whatis going on here?
You lost me there - what is too big or too small about them? The
record counts mentioned in the setup documents are examples - the
counts were accurate at one time, but then if a bug was fixed or a
feature added to boot or restor the number of records would change
slightly.
The various programs change size over time and the documents are not
updated if the record sizes change a little bit.
Oh - you need to have 2 copies of the 'mtboot' file at the front of
the tape. Why (I hear you ask)? Some boot roms actually read the
2nd copy!
The format of a boot tape is:
mtboot
mtboot
boot
<TM>
disklabel
<TM>
mkfs
<TM>
restor
<TM>
icheck
<TM>
<TM> = Tape Mark.
the first file (with mtboot,mtboot,boot) is blocked at 512 bytes, all
the other executables are blocked at 1024 (ignore the typo in the
setup docs).
Good Luck!

Nobody, not even Dennis Ritchie, knows how to get a license for any of these.
Hopefully, when the Unix source finishes its current migration to SCO and HP,
we can ask them for an answer.
P.S Back from holidays, the machine minnie.cs.adfa.oz.au died (out of swap)
on Saturday, and I've just rebooted her, so the mailing list is back up.
I've also moved 2.11BSD into the ftp archive on henry.cs.adfa.oz.au. Thanks

My 11/34 is currently down awaiting replacement of an RK05 head which
crashed rather painfully on Monday (the 13th !).
In the meantime, I'm trying to sort out a new UNIX image for it, using
an emulator on the PC. I have an 11/73 emulator for UNIX (Linux) with
RK05s, and an 11/34 emulator (E11) for DOS, which looks great, but
doesn't support RK05 yet.
The 11/73 emulator runs the v5 and v6 images nicely. The question is,
will these images run on a *real* 11/34 without a floating point
board? The /73 and /34 MMUs are significantly different I believe.
Looking at the v6 docs, the system is claimed to run on the 11/40, /45
and /70, but the /34 was yet to be created at that time, so there is
no information about that!
I'd be very grateful of someone could either tell me of a /34 emulator
with RK05 image support, or confirm if v5/v6/v7 UNIX will run on:
11/34a
128Kw
1xRK05
no floating point
no sep I+D (I guess)
Cheers,
Bob.

Hi,
All of this is very installation specific. The major/minor numbers in the
device inodes need to correspond exactly to the entries in the devtab
structure in the kernel. This is probably something that can be divined by
running nm on the kernel, /unix ? (All this is from memory, my annotated V6
kernel listing is buried at home right now.) But, I'd be surprised to see a V6
distribution that didn't have the rk drivers built in. Another thing to
watch out for is the rk driver, er, device names/numbers that interleaved a
file system across multiple drives.
BTW, is there anywhere one can get a "legal license" to run V6, V7, 2.XBSD on
my pdp11/34's and 11/44?

True enough. The example I gave was correct for the V6 distribution
that Ken Wellsch donated to the PUPS archive, and in which the file
/usr/sys/conf/c.c (generated by 'mkconf' in the same directory) ends
up with the following for the default "rkunix" with rk, tm and tc
drivers enabled, as per the script /usr/sys/run:
int (*bdevsw[])()
{
&nulldev, &nulldev, &rkstrategy, &rktab, /* rk */
&nodev, &nodev, &nodev, 0, /* rp */
&nodev, &nodev, &nodev, 0, /* rf */
&tmopen, &tmclose, &tmstrategy, &tmtab, /* tm */
&nulldev, &tcclose, &tcstrategy, &tctab, /* tc */
&nodev, &nodev, &nodev, 0, /* hs */
&nodev, &nodev, &nodev, 0, /* hp */
&nodev, &nodev, &nodev, 0, /* ht */
0
};
int (*cdevsw[])()
{
&klopen, &klclose, &klread, &klwrite, &klsgtty, /* console */
&nodev, &nodev, &nodev, &nodev, &nodev, /* pc */
&nodev, &nodev, &nodev, &nodev, &nodev, /* lp */
&nodev, &nodev, &nodev, &nodev, &nodev, /* dc */
&nodev, &nodev, &nodev, &nodev, &nodev, /* dh */
&nodev, &nodev, &nodev, &nodev, &nodev, /* dp */
&nodev, &nodev, &nodev, &nodev, &nodev, /* dj */
&nodev, &nodev, &nodev, &nodev, &nodev, /* dn */
&nulldev, &nulldev, &mmread, &mmwrite, &nodev, /* mem */
&nulldev, &nulldev, &rkread, &rkwrite, &nodev, /* rk */
&nodev, &nodev, &nodev, &nodev, &nodev, /* rf */
&nodev, &nodev, &nodev, &nodev, &nodev, /* rp */
&tmopen, &tmclose, &tmread, &tmwrite, &nodev, /* tm */
&nodev, &nodev, &nodev, &nodev, &nodev, /* hs */
&nodev, &nodev, &nodev, &nodev, &nodev, /* hp */
&nodev, &nodev, &nodev, &nodev, &nodev, /* ht */
0
};
The major device numbers are the offsets (counting from 0) in these
arrays, so rk has major 0 for the block device, 9 for the character
device. I would assume that this holds for V6 in general -- if one
were to add device drivers, one would surely extend these arrays at
their ends, not insert anything into them... :-)

What's its copyright? I'd love it, but I'll check with Doug first.

Greetings:
I've been trying to reinstall BSD2.9 on my 11/73. Problem is that
I don't have any of the 'Classic' periperals anymore, like TU-10's
or RL-02's. (I do have an RL02 emulation which works fine on RT-11
but won't go with BSD or TSX, and no docs on it at all).
I have RX-50's, TK-50 and various DU's (RD52,53,54). If this were
a perfect world I would have a TK-50 distribution tape to rebuild from.
Does anybody know how I might be able to obtain?

The version of 2.9 I have dates from 1983 and lacks any support for
TMSCP and MSCP.
Support for those came later, the initial 2BSD driver is dated
September 1985 and has a comment to the effect it's based on the
4.3BSD UDA driver, so 2.10 was likely the first inclusion of MSCP
in a 2BSD kit.
By the time of 2.10BSD the MSCP driver was definitely present.
TMSCP support didn't make it in until 2.10.1BSD in 1989 - I know that
for sure 'cause I did the port.

TK-50 support didn't enter the picture until 1989 and it's a real
beast of a driver (not to mention the bootblock and standalone
driver).
> Does anybody know how I might be able to obtain?
Unless you can find some one with a later 2.9BSD system into which
the MSCP driver was hacked (doubtful but who knows) I think you're
out of luck. I seriously doubt you'll find a TK50 version of 2.9
since that wasn't added until 2.10.1BSD.
On a /73 you're probably _much_ better off installing 2.11BSD
(currently at rev #277) - it's due to enter the archive in Oz any
day now (when Warren gets back from vacation).

It has been suggested to me that since the 11/34a MMU doesn't support
separate instruction and data space, certain versions of UNIX are not
suitable. Does anyone out there have any idea which versions of UNIX
require separate I+D space?
Cheers,
Bob.

Steve Schoultz is really the one to answer this question, but I
seem to remember that BSD2.9 was the last version which worked
on non-I/D-space systems.

The last version of UNIX for the PDP11 which stood a chance of
running on a non split machine was 2.9BSD. I'd expect it to be
a very tight fit though because even on a split I/D machine we
ended up overlaying the kernel (but then even V7 took overlays
to fit - which we hacked into the kernel, at least in the environment
here). A long long time ago I did squish a V7 system into an 11/23 -
not a pretty sight, each command you ran caused the others on the
system to be swapped out (do a "ls -l" and watch the shell get swapped,
when the 'ls' finished then the shell would be swapped back in, etc.)
V6 would be a better match for a non-split (248kb max) machine. By
the time V7 was out the 11/70 was being used as the development
platform and split I/D was becoming more and more necessary.

sms(a)wlv.iipo.gtegsc.com
I posted this query to vmsnet.pdp-11 and alt.sys.pdp11, but following
Warren's complaint that noone was talking on oldunix@minnie I'll ask
you lot too ...
I have on my PC hard disk a couple of rk05 disk images (from Warren's
archive, naturally). Question is, how to get them onto a real rk05
... the real PDP beats the emulator any day after all ...
Naturally someone has workedout how to extract RK05 images to files to
put on the archive site. I'm wondering if anyone has solved the
reverse problem yet ...
I could split up the file into moderate sized pieces (say 250k, RX01
sized bits), boot the PDP (RT11) off RX01 floppy, start kermit and
transfer a file piece from the PC to the other PDP floppy drive. Then
I could mount a fresh RK05 pack, format etc. and run some crafty code
to write the file to the appropriate place on the 'raw' RK05 device.
What do you think?
Another correspondent mentioned that Kermit may be able to write to
"raw" devices directly, allowing me to transfer the file all in one
piece. I'm still waiting for confirmation of that -- seems a little
unlikely to me, but I've been suprised before.
My system is:
11/34a
1 x RK05 (2.5Mb removable type, RK05f I think - or is it j?)
1 x RX01
128Kword
As you can see, backing store is in short supply ;)
I'd sooner avoid writing too much Macro-11 at present, so if the
problem is already solved, I'd love to know how ...
Cheers,
Bob.

Dear All,
I have just had a note from someone who wants to get RK05 stuff on to his
system but might be in a position where his current setup can't do it.
This sort of stuff might be helped if people submitted a register of what kit
they have. This could allow people in reasonable geographic location to help
each other out. FOr instance, if some one had a unix system that an rk05 could
be plugged into then they could do this and then give the rk05's back once they
had the stuff copied over.
To start it off. I have:
1*11/73 (1.5MByte)
2*RD54
1*DHV11
1*TK50
Running 2.11 BSD.
I also have 1*Compaq 386 (486 Cyrix chip)
running FreeBSD
I live in Gloucestershire UK and am willing to help anybody in copying stuff
that I can. I can get access to 0.5inch mag tape RA60 and RL02 if necessary.
Cheers
Robin
