I don't have numbers for anything running under the emulator, but I do have
Dhrystone sources (and some figures for real PDP-11s of various sorts with
various operating systems and compilers). If anyone wants to try it, I can
post the source.

I'd be very surprised if factor used FP. My 7th Edition system's offline ATM,
so I can't check the source.

Well, it is one of the areas that causes trouble on different flavours of
PDP-11. Both DEC and Unix O/S's had all sorts of games being played in the
trap recovery code, according to which processor the O/S thought it was running
under. But AFAIK, that code only gets called if an instruction is aborted,
which I wouldn't expect would happen exactly the same way every time factor was
run (but again, I'm speculating without having looked at the code).

Yes, in the sense that you could perform random-access operations on it. I
used a PDP-8 that had twin DECtape instead of disks. It supported 4(?)
teletypes in a multi-user environment. But DECtape was not 1/2" tape, nor did
it use reels like the ones that later became standard.

Yes to all of those, though there are three standard recording densities
(80bpi, 1600bpi, 6250bpi) and several recording methods (NRZ, NRZI, PE, etc).
There are different standard lengths too: 600' 1200' 2400'.

Shouldn't be hard, unless it's suffered from print-through after 18 years.
It's probably 800bpi (NRZI) or 1600bpi (PE). Whether you can understand the
contents depends on the format of the data, of course.

You have to realize that disk storage on mainframe systems in the
1960's was usually quite small. Almost all "large-scale" processing
was from tape drive(s) to tape drive(s). If you find a really good
reference on sorting and collating (Knuth, for example) a lot of
effort is made on doing things with as little core and disk space
as possible. Most of these methods are still used today on really
large data sets (for example, FFT's on multi-gigabyte data sets
which are never entirely in memory.)

DECtape was very much different from other tape media of the time.
You didn't treat it as a disk in just some ways, you treated it as
a disk in all ways.
At the time of DECtape, the most inexpensive removable disk media was
the RK05 DECpack, which cost about $150-$200 per platter. DECtape was
created as a more affordable "disk-like" removable media so that
each user could carry his files around with him.

A 1600 bpi 2400 foot 9-track holds about 40 Megabytes if you use long
blocks. Other more recent magtapes (i.e. DLT's) hold 40-100 Gigabytes per
reel/cartridge. Some specialized optical tape media hold Terabytes
per reel.

Absolutely. There are ANSI standards for all of the above. Despite
what others claim, interchangability was always rather straightforward,
and the worst problems are the "concepts" not supported by some operating
systems (i.e. Unix lacks file support for anything other than a file that's
just a stream-of-bytes).

Absolutely. Part of my current profession is reading 9- (and 7-) tracks
that are up to 35 years old.

These uses aren't just historical - many of us still deal with datasets
that are Terabytes in size and which cannot be disk (or core) resident.

But in the 9-track world at least, 800 BPI was always NRZI, 1600 BPI
(and 3200 BPI) was always PE, and 6250 BPI was always a specific type
of GCR.
In the 7-track world, recording was almost always NRZI. One manufacturer
did make a 7-track PE system, but it was never a standard.

On a cow orker's 200 MHz Pentium Pro, Bob Supnik's emulator (compiled
with gcc and running under Linux) is about twice as fast as a real
11/73 for most CPU-intensive operations. Speeds for I/O based
operations can range from incredibly faster to incredibly slower
than a real -11, of course, and a lot of the interrupt and device
priority schemes seem seriously out of whack with how a real PDP-11
works. And speed also depends on whether the MMU
is enabled or not, too.
The same emulator running on a 7-year-old 133 MHz DEC Alpha is about
a third the speed of a real 11/73 (slow enough that a lot of 60 Hz
line-time-clock interrupts go uncounted under RT-11, for example!)

Dectape was an attempt to achive moderate amount of storage at low cost

Thats a typical one. Sometimes 4 drives were used plus maybe a disk
system. Two for source material, one for intermediate results, one or
more for programs and the last for final results. Some machines were
very limited in the local memory they had so programs often were broken
into small modules and loaded (chained) as needed on the fly. Imagine
processing 500k of data in a 16k memory where a portion was also used
for program code.

FWIW, I've used the latest (and not yet committed) version of the
Begemot emulator to run 2.11BSD for over a week. In that time, I
applied multiple patches to the system. I did have some as yet
unexplained problems with the assembler, which Steven Schultz
considers to be due to the emulator (more specifically, instruction
restart), but Hartmut Brandt (the principal author) thinks this is
unlikely. vi works as well as vi ever works.

It was a possibility - the only other thing which I've seen cause
similar problems was bad memory/cache. I presumed your memory
wasn't failing ;).
Programs suddenly dying for no apparent reason on otherwise healthy
"hardware" led me to suspect a problem with the emulator. The final
arbiter of course is a real PDP-11 :)
I take it then that the problems went away as mysteriously as they
arrived and that all is well with your system (no more assembler
or kernel recompile troubles)?
Not having any great need of an emulated PDP-11 I've not pursued
the (suspected) bug in Bob Supnik's emulator. Even on a PentiumPro
an emulated 11 is slower than a real 11/73 (and a lot slower than an
11/93 - which I should cease neglecting and stuff a SCSI card into
some day as I did with the 11/73).

Well, not quite. I finally got back to the real work I should have
been doing, and I haven't had time to look at it again since. But
they went into hiding when I tried to show them to Hartmut :-) I think
we still have a problem somewhere. BTW, Hartmut had already upgraded
to PL 40? before I tried to start, so I'm still not completely
convinced that it's not something I did wrong in upgrading.

Interesting. I was running this on an AMD K6/233, which should be
slower than a PPro, and I had the impression it was faster. Does
anybody have some benchmarks?

Briefly, Jean tells me the stuff I saw on his web page (early DEC support)
is called UNIX V7M RELEASE 2.1. There's a copy of _a_ V7M in the archive, but
I've asked Jean to look at his tape so we can compare contents.
John Holden, as you saw, also has a tape with lots of pre-built kernels.
I've asked John if we can get a copy of this tape too.
A few people mentioned Ultrix for the PDP-11. This is probably a dumb
question, but I assume DEC still owns these systems. Would it be possible
(and/or worth it) to ask DEC to make it freely available to licensees?
I guess we could ask Bob Supnik about it.
Thanks again,
Warren

All,
I've just received this reply from Bob Supnik on PDP-11 Ultrix:

I asked him if DEC would permit us to distribute Ultrix to LICENSEES ONLY,
if some license agreement was also distributed. Awaiting a reply....

More evidence of a bug is that 'vi' doesn't work right under Bob
Supnik's emulator, either. At one point Steven Schultz made some
private speculations to me about where the problem might be, but
I've forgotten the details. Is it possible that these two bugs
are both due to FP emulation? Does the 2.11BSD 'vi' even use
the FP registers?

Don't know about vi FP, I could go have a look at the source. No, vi
doesn't appear to use any floating point.
I asked Bob about the factor(6) bug in my Ultrix mail, he didn't mention
it, but he might at some stage. I'll keep people informed.
As for vi, what was the abnormal behaviour?

To the best of my knowledge 'vi' does NOT use any FP at all (other than
the usual 32 bit arithmetic that all programs do if they do any 'long'
arithmetic).
My speculation is that there's a MMU emulation bug somewhere. 'vi' is
a overlaid split I/D program. Overlays in 2.11BSD are done via
'page flipping' (altering MMU registers). Also 2.11 uses the 'expand
downward' bit on the stack (as well as relying on MMR3 - i think that's
the one - for instruction restart after growing the stack). If there's
a subtle gotcha in the MMU emulation that will cause problems
eventually. 2.11 is not alone in using the ED bit and instruction
restart - if the problem is MMU related it could show up under other
systems (V7). It would be interesting to know if 'vi' encountered
problems on V7 but V7 doesn't have usermode overlays so getting 'vi'
to run would be very problematic.

The 2bsd distribution in the archive comes with an early non-overlayed vi
which compiles on V7. However, I haven't got it to work correctly yet. I
suspect that the /etc/termcap entry I was using is not recognised by this
early version of termlib.
This is all irrelevant to the emulator bug, BTW.
Steven, have you mentioned your hypothesis to Bob?

Was dectape an attempt to remedy some of these problems? My

How much data can magtape hold? If magtape was a portable media,
does that mean that the manufacturers agreed on the width of
the tape, the density of recording, the method of recording bits,
etc.?
I have an old 9 track tape from a computer course I took in 1980.
For sentimental reasons I'd love to get a copy of its contents. Is
this possible do you think?

Is 'merge sort' an example of an application that required three tape
drives?

This is the word from Dion, as at 1st April:
Well, we have 12 licenses accumulated here and I haven't got any
"system" set up to deal with these. I will probably just send
you a list of the peoples' names and addresses by postal mail.
Hope that's not too primitive.
I asked if he could send me the list via PGP email, but he countered
that they were all on paper, and he didn't have the time to send me the
list. However, he did say:
I will just drop them into a DHL or similar express shipment
thing. Hopefully in a day or two.
Now, I'm not sure if this means:
+ he will ship the licenses in a day or two,
+ he will ship me the list in a day or two,
+ it will only take a day or two for the list to reach me.
However, the worst-case scenario is that the licenses will be posted
in a day or two, and they should reach you quickly after that.
I checked my bank account, and SCO removed $100 on the 24th March.
I take this to indicate that I am now licensed. I don't know if this
is of much help, though.
I am waiting in anticipation, as we all are.
BTW First person to announce their license in the mailing list wins.
Wins what, I haven't a clue ;-)

I was just browsing for web pages related to PDP-11s and UNIX, and I found:
http://idefix-45.cs.kuleuven.ac.be/museum/pdp/unix-E.html
which has a most interesting paragraph at the bottom:
Officially Digital Equipment did not support Unix. With the
maintenance technicians we made the agreement that the hardware was
OK, when their test programs did not produce error messages.
At the end of 1983 we found out that within Digital there was a
very small group which distributed Unix V7 with support and drivers
for all PDP 11 models and devices. Sources were distributed freely to
all source licensees of Bell labs. From then on we have used that
distribution.
Does anybody know what `distribution from within Digital' is being
referred to here, and how I can get my hands on it, for the archive.
Is this an early Ultrix?
I've mailed the maintainer of the web page in question for more information.

I have an Edition 7 distribution from DEC. The work was largely
done by Fred Canter, along with Jerry Brenner and Armando Stettner. It
had prebuilt kernels as follows :-
CPU Disk Tape
11/23 RL02 TU10
11/34 RK06 TE10
11/40 RK07 TU16
11/60 RM02 TE16
11/44 RM03 TS11
11/45 RP03
11/70 RP04
RP05
RP06
I have a 1600bpi tape, but haven't tried to read it lately.

Ah, I meant to mail that to the list. No matter, it got to where it was most
needed, obviously :-)
I'd suggest you recompile factor if you have the source, but add some
debugging. If you can't do that, you could try running it with adb (the
debugger, man 1 adb for details).

I suspect the FP emulation in Bob's Emulator, so it might be worth
watching the floating point values in the program. Bob mailed me during
the week, and I sent him a virgin binary of factor so he could verify that
there is a bug.

The PUPS mailing list seems to be getting busier. For those `lurkers' who
want to follow the list, but don't want to be pestered by incoming email
every 10 minutes, I've set up a digest form of the list.
The digest will be sent out every Monday and Thursday, or if the incoming
e-mail exceeds 40K in total.
To get the digest version, and to unsubscribe from the normal list, send
e-mail to majordomo(a)minnie.cs.adfa.oz.au with the commands in the message body:
subscribe pups-digest
unsubscribe pups
You still need to send mail to pups(a)minnie.cs.adfa.oz.au for it to go to
the PUPS list and to be included in the digest.

<Well, I've got uncompress working, but I thought having gunzip would

The question is why? Generally compression is a diminishing returns for
computational effort with 80% for the first 10% effort. I can see having
it if needed to gain access to software and the current platform is the
only one.
For sim to hardware transfers simple works better...

I looked at this several years ago and gave up at the save point as
Warren. I looked at compress using 16 bits and hit the same sort of
constructs. After a bit of thinking I believe there may be a way round
it but at the time I didn't know the algorithms used in compress or gzip
so didn't try playing.
The problem is that the compression algorithm needs a 64k space to do
all of its sums in, don't ask me why, if someone could tell us the
algorithm them I would understand a lot better.
These are defined as 64k address spaces which the data page isn't
holding cos they don't fit. If you write a virtual mem system then this
will work. This causes problems in the standalone world obviously but
steve wrote a vm lookalike for 2.11 that uses files, yes a lump of real
mem aka the partition concept with movable windows in RSX would be nice
but we can't have everything, but compress and maybe gip should be able
to be cooked into using such a system for vm. This would be slow but
what are we after?, an all singing all dancing system or something that
would work in the background whilst we get a beer and wait for the
system to install?.

You're right I think. At least compress -b12 works, and as you say, a bit
of extra wait isn't going to hurt too much.
Peter Chubb seems interested in fitting gunzip into 64K. I'll see how he
goes with it.
Thanks all for your comments,

Ok,
I debugged the thing yesterday, it works well. If you want to write
a PDP-11 disk image to a real PDP-11, you might like to look in:
ftp://minnie.cs.adfa.oz.au/pub/PDP-11/Vtserver
and at the file zcat.README there.
Current disk and tapes supported:
hp: RP04, RP05 and RP06 disks.
rp: RP03 disks.
rk: RK05 disks.
rl: RL01 and RL02 disks.
ht: TU16 or TE16 tape drive.
tm: TU10 tape drive.
vt: The Virtual Tape drive.
You can download from any tape to any disk. The Virtual Tape drive allows
you to download the image over a KL11 at 9,600 baud. Any type of disk image
can be downloaded, not just Unix ones.
You will need compress(1). And a bit of patience.
Let's hope someone tries this out!
Ciao,
Warren
P.S I plan on migrating to the 2.11BSD standalone stuff, which supports
more tape drives and disk drives. Sometime.

Well...
my cut-down zcat now works under Linux, and compiles and links
cleanly under v7 on the simulator. But the semantics are
wrong!
Big problem is the lack of unsigned char and unsigned long
types.
I'm gradually going through and finding places where left
shifts, or sign extensions are happening, and masking them
explicitly.
I'm almost sure that at UNSW we had a C compiler on Unix V7 that had
an unsigned long data type...
Anyway, there's progress. And if it all goes OK, then
on machines that have separate I&D spaces, the resulting zcat
will be compatible with gzip everywhere.

As you know, I wrote this list recently about a bug in Bob Supnik's
emulator which manifests when running factor (1).
I've had a chance to do some further research on this, and it seems
to me that the bug is definitely in Supnik's emulator. What do you
all think? Am I onto something? If so, what part of Supnik's code
is probably to blame?
Here's what I've learned so far:
1. factor on Supnik's emulator fails most of the time (see below for
examples).
2. factor works fine on Ersatz-11
2. On the off-chance that I munged the disk images and somehow
corrupted factor, I reextracted virgin images from the tar ball.
factor still fails while running on Supnik's emulator.
3. Peter Turnbull wrote me that factor running on under uv7 on his
PDP-11/23 runs the test case 'factor 6' without error.
Here's what factor does on Supnik's emulator for a variety of values:
factor 6
2
3
17
17 etc.
factor 257
263
263 etc.
factor 263
269
269 etc.
factor 1009 (works correctly)
1009

<There are certain areas of Unix that don't seem quite "done" to me.
<Printing comes to mind (compare Unix benign neglect with Windows'
<universal printer driver).
Most of magtapes short commings under unix are common across most OSs
and are assignable to the characterisitcs of the medium. Mag tape has
several things that make it difficult, one is old (late 60s and through
the 70s) drives had a difficult time starting and stopping without
breaking tape or resorting to complex(then standards) controllers. This
lead to things like large interrecord gaps (start, speed up read, stop,
backspace records, stop, read) due to the inerta of starting and stoping
the reels. Also fixed record sizes were used to make blocks about the
same length so blocks and marks could be differentiated using simple
timers.
Magtape was for the longest time the only portable media, which lead to
the ansi/EBCDIC problems (Evryone else and IBM/HP). It was generally
used for archival storage making file organized access excess overhead.
While often used as block oriented, many systems used it more as a stream
device where the high volume storage (relative to the disks of the time)
capability was available.
When processing was done on early system usually two or three drives were
involved as one of two were for reading and the third was writing results
usually due to memory size limitations of the time compared to the amount
of data. Alot of magtapes lore is a result of historical use.
FYI the idea of tar files had spilled over to CP/M (8080, z80) systems
back in the 80s for distribution sets. It was done usually by creating
an archive set of compressed files (.arc, .ark, .lbr). to get the most
out of limited space of floppies (under 300k) of the time and to keep
programs set and sources together.

I remember this. Somewhere I worked as a student there was a
tektronix box which supported some kind of microcontroller development
system and/or and in-circuit emulator (for things like 8048 / 8051,
though I think it had personality modules). It was a box which was
known to be a PDP11, and had a couple of tek terminals on it, probably
another box with stuff to support the emulators/PROM blowers & stuff,
and it ran Tenix. I had an account on it, but all I knew then was
that it was some kind of Unix. V7 sounds right -- perhaps it was
Tek's OEMd version of this, with (I guess) support for whatever HW
they had + some kind of development environment / x-assemblers & so
on. The box just might still exist somewhere -- I made an attempt to
get hold of it after I realised that PDP11s were cool, but it was hard
because it had been worth a lot of money once and the accountants went
all funny about it.

Hey,
does anyone know if LSX is coverd by the SCO source license? And where to
get sources for it? It was a version of Unix that I played with 15 years ago
on an LSI-11 system with dual AED floppy drives... it was nice in that it
woudl run on a pdp11 that was lacking memory mangaement i.e. a 28kWord
machine....
Shake those gray cells friends and let's see if we can scare this one out of
the woodwork... it would make a lot of ancient pdp11's much more useful.
Regards,
Milo

Well, I've got uncompress working, but I thought having gunzip would
be good as it gives better compression results.

I did use something called "Mini-Unix" on a PDP-11/10, which was a single-
address space machine. It worked, sort of, but had some problems - like,
pipes were implemented as temporary files, so the shell broke things apart
into individual sequential commands... and printing with lpr generally
froze the machine up. There may have been later and better versions, though.
(This was around 76/77, as I recall).

That reminds me. Why can't the 11/73 boot the unix RL pack directly from
console boot dialog? The system boots RSTS and RT-11 packs. Is the boot
block munged/missing? I might add it boots fine using boot/foreign from
rt11.
It's a curiousity as having RT on floppy or HD is not a big thing for me.
But if it can be fixed that would be an improvement.

The 11/73 firmware bootstrap expects the boot block to conform to certain
standards specified by DEC in the early/mid-80's. In particular, the
bootstrap must begin with a NOP, but there are some other requirements
I don't recall at the moment.
The toggle-in bootstraps that DEC supplied didn't do any such checks (who'd
want to toggle tha check in everytime, anyway?), they just read block 0 to
location 0 and jump to it (well, some also assume things about the SP
going somewhere reasonable, and sometimes certain register locations set
to certain things.) And RT-11's BOOT/FOR doesn't make any such checks,
either.

You can either rewrite the 11/73 firmware to not do the check, or you can
rewrite the V7 boot block so it conforms to DEC's standard. The RL02
is a particularly stupid device and requires an inordinately large bootstrap,
so there may not be a lot of free room in the V7 boot block. You can also
stick a "toggle-in" RL02 bootstrap into RAM via ODT and execute that. But
I've decded that for me, the solution of RT's BOOT/FOR is the best, just
as you seem to have :-).

Tenex was a PDP10 (aka DECSystem 10/20) operating system.
Some 10s had 11s as consoles.

The Tektronix manuals say "Tektronix Unix" and "TNIX". Looks like I've
to boot the box and have a closer look at the actual software. I'm
quite sure that it is some kind of v7. Unfortunately, it's just
binaries. I don't think this should be confused with Tenex and/or
PDP10s which had PDP11s and PDP8s as I/O processors in different
places.

Started to get 2.11BSD working on emulator and 11/70. So far:
Started emulator taken from:
ftp://haba@minnie.cs.adfa.oz.au/Boot_Images/2.11_on_rl02/
Made kernel on emulator which supports the actual hardware:
DELUA at non standard addr, RA81, RL02
Moved boot RL02 to 11/70 with RSTS/E
Made bootable RA81 on 11/70
Untar:ed usr from
ftp://haba@minnie.cs.adfa.oz.au/Distributions/ucb/2.11BSD/file6.tar.gz
....And now the binaries from that tar file crash with "unknown system
call" However, the binaries distributed in the disk images work. Any
clues?

Greetings -
No, there is only 1 2.11BSD (in the sense that there are NOT
competing versions or distributions).
What happened I believe is that the Boot_Images/2.11_on_rl02 is older
than the files in Distributions/ucb/2.11BSD.
I have not looked at the Boot_Images/2.11_on_rl02 files to determine
when they were created (what patch level, etc.). On your RL02 system
what do the first two or three lines of /VERSION?
Anyhow, between the time that the 2.11_on_rl02 images were created
(I did not create them) and December-1997/January-1998 several new
system calls were created _AND_ the entire system was recompiled
and relinked. That is why you can NOT use binaries from the
Distributions/ucb/2.11BSD with earlier kernels. There is UPWARD
compatibility (old binaries can run on new kernels) but not backwards
compatibility.
What you need to do is build a 'tape' (using 'makesimtape' if you
need to use Bob's emulator) from ALL of the files in Distributions/ucb/
2.11BSD.

Hi all,

I've looked everywhere I can think of on the PUPS site, but couldn't
find 'makesimtape'. I couldn't find it among the source of Bob's
emulator. Where can I get a copy of this program?

I don't think Bob's latest emulator has got this. I've hacked at another
program to do this, and I'll make it available tomorrow.
Bob has asked me to submit this to him for inclusion in his simulator.

It's in /usr/src/sys/pdpstand. Look in file7.tar.gz from the 2.11 part
of the Distributions and it should be somewhere in there.
makesimtape is a hacked up version of 'maketape', the syntax and data
file are the same so if you know how to use 'maketape' to create
bootable tapes you're all set.
The program is short enough I'll include it here. It should compile
and run with minimal tweeking on any 'BSD'ish UNIX system.

Ah, I should point out to the readers of the mailing list:
The PUPS Archive is NOT what you get by going to
ftp://minnie.cs.adfa.oz.au
as anonymous. Obviously, the archive has to be password
protected, and so the anonymous ftp on Minnie isn't the Archive.
I suspect Ed has been walking thru the anonymous area, which is why he
could only find Bob Supnik's emulator.
Anyway, Steven has provided a solution. Steven, could you put in
#ifdefs for particular endian architectures???
Cheers,
Warren

Thanks!
I was just a plain old user during my college days, so I've never had
much contact with magtape.
But since magtape seems the easiest way to get data into and out of
Bob Supnik's emulator, I've been fooling around with (simulated)
tape a lot lately.
To me (or maybe I just don't know what I'm talking about) it seems
like magtape has a number of deficiencies:
No filenames or directory structure: just an ordered series of
bytes. Which would seem to imply that people must've used tar *a lot*
to get these services. True?
Padding of files to a multiple of the block size. Yuck! If I have
a 312 byte file, I do not want to save it and then retrieve a (to my
eyes anyway) different 512 byte file which has been padded with
200 bytes I didn't put there. Did this padding of files ever have
any bad effects?
So I was wondering, what *did* people use magtape for on these old
Unix systems?
Here are my guesses:
Bad Old Days What we use now
================================
Archival storage (tape, CD-Roms, Zip drives, floppies)
Application Software distribution (WWW, CD-Roms, ftp, email,
floppies)
System software distribution (CD-Roms, ftp)
Backups (tape)
Transfering a little data (Floppies, email).
Transfering a lot of data (CD-Roms, Zip drives, ftp, tape)
Have I left any significant use for tape out?

All,
I've had a few people ask the question:
I have a PDP-11, you have disk and tape images for old Unixes. How do get
the images onto my actual disk/tape so I can install Unix?
If anybody has sucessfully done:
image -> tape -> install to disk -> working PDP-11 UNIX
image -> install to disk -> working PDP-11 UNIX
or any other variant, using any intermediate system (e.g KSERVE & RT-11),
could they please drop me a note with some _details_ of what they did.
I'd like to add this to the FAQ, as I suspect this is going to be a
popular question as people receive their SCO UNIX licenses.
Thanks in advance!
Warren

Most (non-Unix) minicomputer OS's had built-in support for
ANSI labeled files, which do have filenames (and header bytes to
specify record sizes and number of records). Folks who used Unix
either made their own labeled tape facility (e.g. Ultrix and
OSF/1 "ltf") or just used "dd" and a lot of hard work.
The lack of a record structure that is built-in to the Unix filesystem
really makes things like tape transfers quite irritating. The rest of
the world isn't always just a stream of bytes!

Now far for me to be defending 9-track tapes on UNIX systems, and I'm
the first to admit I've not encountered *all* the various methods used
everywhere to write tapes, but it took no time for me years ago to write
a program that would pull blocks off a tape (by trying to read the max
limit block size) and recording the actual block size read. Oddly enough
when matched with a program that read this "raw format" info, it was sure
trivial to reproduce the tape... but I'm sure I'm missing something.
Luckily on my UNIX systems I am unencumbered by someone else's potentially
proprietary or undocumented "file structure" - both by the system and
by the media. -- Ken

All,
I spent some time last night adding stuff to my virtual tape server.
I have to test it today, but essentially:
Box with serial line PDP-11 with
tape server -----------> uncompress & dd
+ disk_image.Z (bootable)
In other words, you can boot to an uncompressing dd, and suck over
any disk image, without actually requiring an operating system.
With this approach, you obtain an existing disk image that will work,
or you use one of the PDP-11 emulators to create a disk image with a
Unix kernel configured for your system. You then compress it, and
suck/splat it to your real PDP-11 via the serial line.
Now, what I've currently got will cope with -b12 compressed files. Can
someone tell me if it would be feasible to fit a gunzip into 64K?? Even
if it could only cope with gzip -1 files.
Cheers all,
Warren

Well,
I'm currently sucking a .Z compress RK05 disk image over a 9600 baud
DL11 port; it seems to be working. Pity -b12 gives such low compression, but
I guess any saving at 9600 baud is worth it.

If my understanding of 'gzip' is right then the alogrithm works on
32kb blocks of data and the '-N' level has little to do with the
memory consumption. Rather, as the -1, ... -9 level increases the
amount of work that gzip puts into the compression increases (the
difference between -6 and -9 is only a few percent in final output
size but the length of time taken is quite a bit higher).
Of concern would be getting the gzip sources to compile with a non-ANSI
compiler on a non-32bit machine (sizeof (long) == sizeof(int) is an
endemic assumption I wager). Well, ok - there is the worry that
you will grow old waiting for it to compress something ;-) Gzip is a
lot more cpu intensive than compress.

I'm only thinking of implementing gunzip on the PDP-11. I've got
uncompress -b12 running standalone right now, but gunzip would be a big
win: you gzip -9 on a 32-bit system (higher compression) and gunzip
on the PDP-11.
I just don't know if the gunzip would fit. Isn't there a gunzip for MS-DOS?
Surely we could leverage something from it?

I think Steven described the main thing: will it run in 64K? I've popped
some mail off to Jean-loup, who was involved with writing gzip.
If we can get gunzip running in 64K on V7, I can then move it to a
standalone program with minimal effort: the V7 standalone library
provides open, close, read, write, printf, exit.
Cheers!

I've done a little bit of playing around with gzip 1.2.4. It works on
16 bit MS-DOS platforms with a bit of tweaking, and I got all modules
to compile under 2.11BSD. Unfortunately, I ended up with a couple of
undefined references on linking, and I haven't had time to look at it
in more detail. On the whole, though, it looks as if it could be made
to work, maybe with a little tweaking.

There are certain areas of Unix that don't seem quite "done" to me.
Printing comes to mind (compare Unix benign neglect with Windows'
universal printer driver).
My understanding is that the Unix philosophy was to provide raw and
cooked drivers for all the devices. That way you could have access
to the hardware if you needed it, or cushy operating system services
if you didn't. Only the cooked mode for the tape devices doesn't
seem to do much more than the raw mode.
Seems to me that they could have easily added file system services
for tape drives to the kernel, just like they did for hard disks.
Was support for tape another area that the Wizzards at Bell Labs
neglected in favor of other more urgent needs?

I don't know whether this is a bug in the factor (1) program (which
seems unlikely) or the emulator. Can someone try factoring numbers on
a real pdp-11 and tell me what happens?
On the emulator when I type in a number, factor prints out the
prime factors, followed by an infinite series of 17s. So, for
example
factor 6
2
3
17
17
....
I might add that I had bc running on the emulator calculate pi to
30 places and the results were identical with gnu bc on my linux box,
right down to the last digit. Very impressive.

Are gzip and gunzip comparable in size? I'm curious if the
decompression is more 'address space' hungry than the act of
compression (or vice-versa).

It's actually 56kb or less - have to leave room for the stack and

I would be very surprised if this was a bug in the emulator.
In any case, I tried it on the begemot emulator, running 2.11BSD:

2
3

I haven't looked at the process images on systems on which they run.
I suspect it wouldn't relate directly to 16 bit platforms anyway,
since they have a slightly modified algorithm.

OK, I've found the problems with gzip, and they're not encouraging.
It would appear that the undefined references are undefined because
they refer to data which is too large. Here's the preprocessor
output:
uch inbuf[ 0x8000 + 64 ];
uch outbuf[ 16384 +2048 ];
ush d_buf[ 0x8000 ];
uch window[ 2*0x8000 ];
# 194 "gzip.c"
ush prev[ 1<<(16-1)];
ush tab_prefix1[ 1<<(16-1)];
uch and ush are uchar and ushort respectively. Obviously there's no
way of fitting this into a 64 kB address space. Possibly there's a
way of shortening the buffers, but it would take more time than I have
right now. Sorry for raising your hopes.
There are other zip-compatible programs out there, such as unzip.
Maybe somebody should look into them.

There were several tape handling programs that were standand from edition 5
onwards, including tap, tp, dtp, itp, tar and cpio. The only major tape standard
around at the time (other than IBM) was ANSI, and several programs (not from
Bell) were available to handle these. The ANSI tape structure was very
inefficient with tape usage, since it used small record sizes and lots
of tape marks. TAR did a better job (for Unix) and only lacked labels
to name the tape.
Putting tape filesystem handling into the kernel was definately against the
original 'small is beautiful' philosophy. In any case, tape handling was
very easy via the raw interface.
As a side issue, Plan 9 has the ability to mount a tape as part of the
namespace and only reads the file contents if the file is opened.

You need to decrease the window size -- try setting it to 8k (instead
of 32k)
There should be a
#define WSIZE 0x8000
somewhere.
It may be worth playing with a decompress only version -- compression
will take more space than decompression (you need two windows rather
than one, for a start). inbuf can be smaller, too. Try 512 bytes to
match the disc record size.

Correct. Unfortunately, it's not as simple as that. Here's the
definition:
#ifndef WSIZE
# define WSIZE 0x8000 /* window size--must be a power of two, and */
#endif /* at least 32K for zip's deflate method */
> It may be worth playing with a decompress only version -- compression

Yes, that was really what I was thinking of doing with unzip, rather
than excising the unzip part from gunzip.

Sure, once I get into serious modifications I can try a number of
things. The trouble is, I just don't have the time. I thought it was
worth 15 minutes to see what it would do, and the first attempts
looked encouraging. Unfortunately, the second attempts didn't :-(

You are correct. I works.
Now I have four systems running some form unix (Linux, Venix, Ultrix, and

they might as well be from different worlds. Granted, they are different

So is the DECUS C compiler, I hear. Is there any native C compiler
for the PDP-11 which isn't derived from V6/V7?

You need to fetch the Xinu distribution. I haven't got time to unpack the
compiler sections right now, but you can get the whole tarball at

Hmm, that's what I'd heard. Perhaps the person who told me this was wrong.
Can anybody tell us the correct origins of the DECUS C compiler?

I had this idea for a t-shirt to celebrate the release of the SCO PDP-11
licenses. The front says:
I am
LEGALLY
CONTAMINATED
by UNIX
The back has as much kernel source code as you can print on a t-shirt.
Near the middle is the comment /* You are not expected to understand this */
Sound good?

Yes, of course you will. You will also have to kill anybody who attempts

Hmm, how can we rectify this?
How about a list of versions covered by the SCO License, arranged randomly
around the `I am LEGALLY CONTAMINATED by Unix' on the front?

# Hmm, that's what I'd heard. Perhaps the person who told me this was wrong.
# Can anybody tell us the correct origins of the DECUS C compiler?
One thing I can tell for sure: the DECUS C Compiler and the K&R CC are
completely different in their origins. I'm about 90% sure the DECUS XCC
is written in MACRO-11.
The reason I'm so sure is because we were looking at a suitable C compiler
to run on our 11/34 back in 1989 and we first mungled with the DECUS XCC.
But this one had several deficiencies, among them I remember lack of blocks
within functions, local variable initialization, difficulties with typedefs/structs.
Maybe, Harti could tell more.
We were looking into Johnson's pcc, but this one turned out to be a too big
piece of work and to slow to run on our 128 KWord machine.
Harti tried to port the Whitesmith CC from RT11, and it ran, but there were
deficiencies with the RT emulation, so we dropped that.
Finally, we took the K&R UNIX CC and reworked it so that it would pass the
DECUS XCC to produce the stage one. We wrote our own unix assembler supporting
the RSX object file format from scratch. Later, we recompiled the K&R CC on
RSX with itself. This system became our workhorse for the next 2 years, the
compiler is still amazingly fast, both in terms of runtime and the code being
produced. (Quoted: Harti)
So here are the 4 different original sources of C compilers for the 11, though,
admittedly, 2 of them would run on DEC's original OS, not on UNIX, which I guess,
makes them somewhat irrelevant to PUPS. Am I right here ? (Where do we draw the
boundary ?)

I should say (and Joerg reminds me) that he & Harti sent me a t-shirt
a couple of years ago with a copy of boot/login sequence of V7 on the
front, and the section of the V6 kernel with the comment above on the
back. I wear it quite a bit, and my fiancee likes it too, but probably
for other reasons.
Thanks Joerg!

The /* You are not expected to understand this */ is also on the second
page of Peter Salus' A Quater Century of UNIX, explaining a lot of folklore
behind the UNIX history, including things like "a tape was found on the
street to contain ...".
The "contamination" term is (as far as I can tell) originated at Berkeley.
When USL sued UCB for violating AT&T UNIX copyrights, it became apparent,
that anyone ever having had a look at the original sources would be "infected"
and be disallowed to distribute code that vaguely resembles anything in UNIX.
Kirk McKusick then showed up with "Mentally contaminated" stickers for everyone
attending the 4.4BSD Kernel Internals course at the Winter 1993 USENIX
Conference, since he would present us - guess, what - source code! (of 4.4BSD)
I still have the sticker somewhere in my collection.

Yes, I'd love to lay my hands on the `50 bugs' tape. For those who don't
have Peter Salus' book (get out there & buy it!), this tape had fixes to
V6, but the lawyers prevented Bell Labs from distributing it. So, someone
`found' it lying in the street and that's how the patches found their way
out of the Labs.

I got one of the `Free the Berkeley 4.4' t-shirts. Good stuff.
Kirk's the guy who is working on making the 4.xBSD releases available on CD.
Please don't hassle him about it; I'll do that 8-)
I've informed him that the SCO license covers 32V. Therefore, a lot of
people will soon become eligible to receive 4.xBSD.

I think I have the RX driver somewhere. Might take a while to find, though.

Someone can correct me if I'm wrong but ISTR that the dateset at startup does
just set MM/DD HH/MM and relies on reading the year last written in a file
somewhere. If you run 'date' as root once the system is up, you can set the
year as well.

Mine has a script which includes a umount (you won't strictly need that for a
single drive) and a sync or two, and a little message. It might have a 'kill
-1 1' to take it to single-user mode. Other than that, just halt it after a
sync.

The probability source license is currently low, that cost is currently
out of my reach. The other problem with only a RL02 I doubt there is
compile space enough. The need to compile to get a bigger device is
hampered by the lack of a bigger device. A built kernal would be
desireable. In the mean time I can do a lot of learning off this one.
My wish list is MSCP disks, RL02, RX02, DLV11j, TK50 support and
networking. That's likely too much.
I'd be happy if I could mount a RX02 or MSCP disk even if I can't boot
off it.
That reminds me. Why can't the 11/73 boot the unix RL pack directly from
ODT/console boot? It does boot RSTS and RT-11 packs. the boot block
munged?

Well v7 binary runs seemingly well on my 11/73 with the kitchen sink
(the extra and unusable accouterments). It doesn't use much though!
The Rl02 disk does have about 5mb space.
One thing I'd like to do is have some additional storage other than the
one RL02 drive I have. I figure that could easily be a RX02 but it's not
obvious how to add that (to V7unix that is). The RQDX3/RD52 would be
nice but I'll settle for a RX01/2.
The other is the date is 1988... month and day are setable but year?
Is there any way to get it to stay in 8/n/1 (my system(s) default) rather
than 7/e/1.
The last one bugged me some... there is no shutdown! To kill the system
all I could do was make sure there weren't any excess processes running

The kernel you got probably doesn't have much else. I could build another

# man date
DATE(1) DATE(1)
NAME
date - print and set the date
SYNOPSIS
date [ yymmddhhmm [ .ss ] ]
DESCRIPTION
If no argument is given, the current date and time are
printed. If an argument is given, the current date is
set. yy is the last two digits of the year; the first mm
is the month number; dd is the day number in the month; hh
is the hour number (24 hour system); the second mm is the
minute number; .ss is optional and is the seconds.

What serial devices do you have? I think V7 expected hardwired things
like KL-11s.
Anyway, here's some of the stty(1) manual.
SYNOPSIS
stty [ option ... ]
DESCRIPTION
Stty sets certain I/O options on the current output termi-
nal. With no argument, it reports the current settings of
the options. The option strings are selected from the
following set:
even allow even parity
-even disallow even parity
odd allow odd parity
-odd disallow odd parity
50 75 110 134 150 200 300 600 1200 1800 2400 4800 9600
exta extb
Set terminal baud rate to the number given, if
possible. (These are the speeds supported by the
DH-11 interface).

I think that's all you could do.

Thanks to a member I now have V7 (supnik) Binary on RL02 to try out.
Several questions:
What hardware does it expect (besides RL02)? This is so I can configure
the 11/73 or 11/23 as it expects.
When I boot it on the 11/73 (1mb ram, RLV21, RX02, RQDX3(rd52/RX33),
DLV11j currently) using RT-11 BOOT/FOREIGN I do get a "@" and it's
not ODT. What commands do I issues to get going from there?

A good idea, but...
I hate to appear obtuse, but this doesn't tell me either. Are you
saying I should sign where it says "By"?

No, just fill in the top section. Leave the `by' section alone, as you
ARE your own representative.
The only time you'd fill out the bottom section is if you were buying
a license for a company, e.g
Sproggs Inc.
5 Looney road,
SPOTSWOLD. NSW. 2001
by
Warren Toomey
etc etc etc.
Hope this helps.

Subject: RQDX3 problems
Sender: owner-pups(a)minnie.cs.adfa.oz.au

Hi pdp people!
Few days ago I wrote about my hardware problems and asked
for hardware guru. Now I've solved some of them -
I checked my backplane and it was 18-bits I wired
insufficient A19-A21 signals and my CPU acessed memory and
now it runs ok. But! I still do not know what happens to
my RQDX3!
I know that this question has little relation to UNIX
and apologize for that.
I hardly suspect circuitry fault but may be some
other reasons. It looks like this:
-My RQDX3 is now connected to simple 5-inch floppy drive
when I power up the machine I see no activity on ANY
pin of RQDX3 to RQDX SIG. DIST. 50-pin connector! I mean
there is no triggering signals hence my floppy
also does nothing. When I try to execute bootstrap or
simply debug RQDX3 registers from console it looks like this:
RESET
CLR @#1772150
<checking 1772152 - it holds 5500 - kinda normal>
MOV #100000,@#1772152 ; controller passes INIT step 1
; no ints enabled, no vector specified,
; UDA OWN bit set. Rings are zero length
<checking 1772152 - it holds 10000 - step one passed>
MOV #xxxxxx,@#1772152 ; controller passes INIT step 2
; specifying low address bits
<checking 1772152 - it holds 20000 or something alike -
no error bit is set - I'm sure- step2 passed>
MOV #0,@#1772152 ; controller passes INIT step 3 - specifying
; high address bits>
<here we can wait for eternity!!!!!!!! Step 3 will never complete>
Does anybody know what does it mean? I also have TMSCP TQK70
controller but no tape drive for it. When I try to run it there
is absolutely similar situation - I think this happens each time
[T]MSCP controller tries to powerup without any drives connected to it.
So I'm looking for help from somebody who can give a hint
about which signal should i check to assertain in absence of hardware fault.
I have no drawings for RQDX3 neither user's guide. It can even be caused
by wrong setting of switches/jumpers - I dont know.
Stacy.

Greg,
Since none of the responses seem to really answer your question,
here's what I did:
I signed my name on the very first line where it says "Name".
I then printed my name on the line where it says "Print or Type Name".
If this is incorrect, I guess I'll get it back!

I'm trying to set up a cross-development environment for 2.11BSD
(running under 4.4BSD), and I've run into trouble because the
assembler's written in, well, assembler. It would be Real Convenient
if I could find an assembler written in C. Does anybody know of one?

Tim Shoppa I believe is familiar with the "chip" or "sunchip" tar bundle

Vaguely. I'll try to track down the exact reference - I'm not
sure whether your referring to the DECUS C package or not.

I seem to recall that the DECUS C compiler is written in MACRO-11 assembly -
and pretty much a straight translation of the V6/V7 C compiler - but
with different run time libraries for RSX and RT-11. Does
this ring a bell? Or am I completely on the wrong track?

Taking a quick look at the DECUS C package, I see that isn't the answer.
There's an "as"-style assembler there written in MACRO-11, though :-).
I think you were referring to the XINU-11 package available by anonymous
ftp from sunsite:
ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/xinu
in particular, if you look in
ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/xinu/
unpacked/src/cmd/as11
you'll find the "as11" sources in C, specifically written for BSD4.3 on
a VAX.
I have to admit that I'm not fully aware of the copyrights regarding
the XINU package. If research shows that this is freely distributable,
is this something we'd want to distribute through the PUPS archive,
Warren?

Tim,
No, the DECUS C compiler is a very different kettle of fish. Sorry to
be so vague - I can only go by memory now as all my archived info is on
CD-ROM's at home. Back in the mid to late 80's a few folks made available
a bundle put together by the folks at Purdue I think - I believe it was
related to Dr. Comer (sp?) and the Xinu stuff - but this bundle was
intended to provide a compiler environment on SunOS systems of the mid
80's to teach lower level system stuff - I've forgotten if it related
to simulating an 11 or was instead just for a cross-compiler environment
to build Xinu mini-kernels on faster platforms to then download to the LSI
11 testbed. One place I picked it up (via FTP) called it "sunchip.tar.Z"
or similar, while another I think just called it "chip.tar.Z."
I mentioned you only because I do remember grabbing it from your sunsite
archive while you were still at Caltech and later sending e-mail WRT the
licensing thing.

Xinu is freely distributable, as long as it's not sold as a competing
product to Doug Comer's book. It's in the archive.
Another solution for a assembler in C is some stuff I've got from a
Russian, who `ported' either cc or pcc to a Sparc, as a cross-compiler.
Greg, have a look in .miscfiles. If someone can make some order out of
this, I'll put it in the archive.
To the PUPS readers, there is a whole lot of stuff I've got but I haven't
added into the PUPS ARchive as yet:
+ System V (SCO license doesn't include it)
+ copyright stuff I haven't cleared it's release yet
+ unsorted jumble Someone has to categorise this
I could put the unsorted jumble into the PUPS Archive. Yes or no?
P.S Woke up to a barrage of email today. Wading thru it....

That would cerainly put it well into the v7 era 9by thre years). But there
were several differences, as I'm sure Tim knows, and some people didn't change.
I'd guess this one has back-ported some v7 stuff onto what was otherwise a
'legacy' system.
I think the RL02 drivers were written in Boston for v7 (or am I thinking of the
RX02 driver?). Maybe v7.h has something to do with allowing this driver to be
used?

I don't know, but if anyone else does, please tell! My 11/23 system has a
kernel panic if I try to run it on an 11/73 (by swapping out the CPU board).

Well, this is what V7.h says:
#DEFINE V7CODE 7 /* IF COMPILING V7 COMPATIBLE CODE */
#DEFINE V7 (U.U_SYSTEM == V7CODE)
and this is what a config file looks like:
# CAT CONFIG.MLAB

CONSOLE
SYS
MEM
RL
RX2
ROOT RL 0
SWAP RL 0 19000 1480
CPU 23
FPU
DL 5
LTC
It also looks like there's support in the sources for 11/34's and 11/45's,
in addition to the 11/23:
# CD CONF
# LS
ADEVS C.C DATA.S L-MLAB.S MAKE-MLAB

Maybe it is the CPU and not the memory that's causing the problem - I was
probably a bit premature in jumping to the conculsion about the memory
(perhaps my 2.9BSD experiences aren't applicable here.)

Sure. Warren's already moved the RL02 image to Boot_images in the PUPS
archive, and at some point someone (me? Warren?) might find enough
copious free time to strip out the sources.
The big problem with this V6 system at the moment is that I can't find
the 'mount' executable. I suspect that the system manager might have removed
or (more likely) renamed it as a security precaution. (Security? Unix?
well, you can try...) I'd like to mount one of the user disks on a
second RL drive, but without 'mount' this is hard. Anyone have any ideas?
"/dev/rl1" is real and works fine, as I can "od /dev/rl1" without a problem.

Many thanks to Pete Turnbull, who pointed me towards /etc/mount.
Some of the "user" disks appear to be corrupted. Anyone care to tell
me where to find fsck?
Tim.

Tim,
fsck doesn't exist yet in the V6 world. you want icheck and dcheck... they
need at least one argument which should be the name of a raw device
containing the filesystem you want to check. (Using the block device anme
will work but be much, much slower.)

Guys,
Just got this in from Dion re the license. No word as to date of
availability yet, I did say `we're waiting....' though.
I sent Dion a draft set of instructions on how to get the license.
Part of his return email goes:
> 4. For AUTHORIZED COUNTRY, I suggest writing:
>
> All countries not excluded by Section 5.2
Yes, very good. I have no idea how to find that damned
govt list. I think our reference is out of date but who

No, it doesnt say that. It says that on our request, you must
furnish the list, but we dont demand it up front. In practice,
I doubt we will ever ask anyone to furnish this, much less
do an on-site visit. Of course, it might be a fun way to
win a trip to Australia if I volunteer to go on a tour to
see that our highly valuable intellectual property is
being treated right... ;-)
That sounds good to me.

Subject: PDP-11 UNIX Src Licenses Available
Hello, you are receiving this mail for one of the following reasons:
+ you signed a petition urging SCO to make source licenses for
PDP-11 UNIX available
+ your filled in a survey detailing what you wanted in such a
source license
+ you are a member of the PUPS mailing list
I am glad to announce that, as a result of the petition, SCO have made
source licenses available for most versions of PDP-11 UNIX. The essential
details of the license are:
Covers research Editions 1 to 7, and 32V.
Covers derived versions of UNIX which ran on PDP-11s.
Specifically excludes System V onwards.
Full source code, binaries and documentation.
Personal, non-commercial use.
Exchange of sources and modifications to other licensees.
Non-disclosure to unlicensed people.
The cost is US$100. Details on how to obtain the license are available at
http://minnie.cs.adfa.oz.au/PUPS/getlicense.html
SCO will not ship any media with this license. The PDP-11 Unix Preservation
Society has a number of volunteers who are prepared to cut CD-ROMs and tapes
in order to distribute the PUPS Archive of old Unix software to licensed
people. Details about this archive are available at
http://minnie.cs.adfa.oz.au/PUPS/pupsfaq.html
We would like a few more licensed people to volunteer to create CD-ROMs and
tapes, to take the load off the existing volunteers.
Finally, none of this would have been possible without the immense support
which we received from Dion Johnson within SCO. He battled with the legal
eagles over a period of 18 months or so to make the license available. If
you can, please send Dion a thank you card at the address
The Santa Cruz Operation, Inc.
400 Encinal Street
Santa Cruz, CA 95061-1900
United States of America
Attention: Dion Johnson
This will be a surprise for him, but I'm sure he will appreciate your
thanks.
In turn, I would like to thank you all for your support. Without the
signatures on the petition, none of this would have been possible.

Most of you on the PUPS mailing list should have received notice that SCO
are now selling the PDP-11 Unix source licenses we have been waiting so long
for. If not, details are on the PUPS web page, and at:
http://minnie.cs.adfa.oz.au/PUPS/getlicense.html
We only have 6 volunteers ready to write media (CDs, tapes) holding the
archive of PDP-11 Unix material. Anybody else want to volunteer?
SCO will let us set up password-protected ftp sites. I will set up the
PUPS archive here for password-protected ftp. Would anybody else be prepared
to mirror this and also provide password-protected ftp? I'd like one
in the US and one in Europe.
Cheers all,
Warren

You probably don't need to change anyhing on the RQDX3 -- they're usually set
up correctly (because they'e not often changed :-)

During init, the RQDX3 probes the disk(s) to see what's there. For a floppy,
it checks for an RX50 by selecting the drive, finding track zero, and then
switching the side select. On a real RX50, which actually behaves as two
separate single-sided drives, this turns off the track zero signal; but not on
any normal drive. There's a way to fool it, but you need to modify the drive
or add a little circuitry. However, if you can find an RX33-compatible drive,
that would be more useful anyway.

Big problem: BSD2.9 doesn't support your disk (RQDX3) or tape (TQK70)
controllers. I'd suggest BSD2.11, but it doesn't run on your CPU.

The best place to ask about these things would be the usenet newsgroup
vmsnet.pdp-11.

That's almost two problems :-)
It might be possible to retrofit [T]MSCP support into 2.9 but it would
be a lot of work and a system with both MSCP and non-MSCP devices
would be required.
Swapping out the cpu card for a KDJ-11AB (M8192 if my memory hasn't
completely faded) wouldn't be too expensive and would speed things
up too. Hmmm, might need a MXV11 bootrom card. Perhaps a KDJ-11BB
would be a better way to go.

I just got V7 to load on my 11/83. Killes 2 hours playing wump.
Who says you need grpahics for games?
:)
Anyway, I know there's no source liscense yet, but can I get someone to
build a kernel for me? I wouldn't have to see source... It'd be real neat
to hang this off a termserver and allow telnets... I'm gonna do that
with my RSTS box real soon, the only limitation here is that V7 is only built
with support for the console.
I have the V7 image downloaded from DEC. I kermitted it to the 83, and did
COPY v7.DSK/FILE DL0:/DEVICE
It truncated something, but FSCK says the pack is fine.
I have to load RT-11 from the MSCP, then say BOOT/FOR DL0: to start V7, though
because if I tell the ROM to load DL0, it dies saying the disk isn't bootable.
But at least it runs!

Hello,
I'm trying to revive a PDP 11/04, but not having much luck at the moment..
I got a serial terminal hooked up to it, and upon bootup, it gives me the
following on the display:
<triangle sign><triangle sign> 177777 177776
$
apparently, $ is some sort of a prompt. It only accepts two characters,
and after, it seems, any pair of characters, will go on and give me a new
prompt.
Is this some sort of a ROM debugger? What can I tell it? I think I've
tried almost every combination of 2 letters without any success..
Some info about the PDP:
It's a 11/04, with a dual 8" floppy drive and some big cage made by MTS,
with nothing in it but a large number of slots. Has some buttons saying
'STATION 1 DUMP', 'STATION 2 DUMP', and so on.. The floppy drive has two
8" floppies in it, one of them appears to be some sort of a system floppy,
the other has no label.
Does this look like even remotely salvageable? :)

Commands available at this prompt include:
L<space>nnnnnn<CR> - to set an address
E<space> - to examine the address set with L
D<space>nnnnnn<CR> - to deposit at an address set with L
S<CR> - begin running at the loaded address
The console ROM is very picky; all letters need to be in upper case,
and you need to type <space> and <CR> in exactly the right places.
It's also very stupid, in that if you try to Examine or Deposit to
a non-existent address, the only clue you get is that the RUN light on
the goes out and you have restart it from the front.

It'll never run a modernish Unix, but it will run RT-11 just fine.
Is the floppy controller a DEC RX211 (M8256) or RX11 (M7846) or some
third-party clone? Are there any boot ROM's on the M9312? The RX01
boot ROM is 23-753A9, and the RX02 boot rom is 23-811A9. If you've
got a third party RX clone controller, it may have the boot ROM on that
board. Try examining addresses 173000, 173200, 173400, 173600, and
171000 to see if a boot ROM might be living at any of these addresses.
As this is very non-Unix related, you might want to ask any other questions
you have on a more general PDP-11 related forum, such as the Usenet newsgroup
"vmsnet.pdp-11".

About formatter..
The VAXstation 2000 can format iron beds.
You plug in 'any' mfm drive and if the enter TEST 53.
If the machine does not recognize the drive, it will prompt you for drive
parameters.

I've been sorting through some RL02's that came with a 11/23 system
that I bought at a UBC SERF sale a year or so ago. On these RL02's
there is at least one bootable V6 system, apparently generated
specifically to be run on a 11/23. This ought to be of some interest
to folks with real 11/23's with RL02 drives, as the other V6 systems
that I'm aware of don't have RL02 handlers.
Here's the question: this RL02 apparently has kernel sources in
the directories /sys/ken and /sys/dmr. Does the presence of these
files mean that I can only distribute images of this RL02 to those
with source licenses?
A non-legal question: the system identifies itself as "v6" when it
boots, but there is a "v7.h" header file in the /sys directory.
Is this maybe really a V7 system? Or maybe from an era when the
trnasition from V6 to V7 was being made? Datestamps on the files
are from 1982.
For those who are listed, a log produced while running in single-user
mode from a copy of the RL02 pack.
Note that although the system was generated for a 11/23, it's
running on a 11/73. The fact that it has more memory than "max" seems
to confuse the system horribly when it goes into multi-user mode. Short
of doing a lobotomy, is there any way to get around this?

All,
I'm starting up a FAQ on the archive of PDP-11 Unix stuff and how to
use it. What I've got so far is at:
http://minnie.cs.adfa.oz.au/PUPS/faq1.html
but not yet linked to the other pages.
I'm happy to take other questions. I'm _very_ happy to get answers! Answers
will have attributions of course. This is a back burner thing, but I'll go
back through the mail archive and see what I can come up with.
Also note: I will add a table of contents to the top at some stage.

NIkolai!
Your problem MIGHT be because somebody shuffled the cards for you!
There are some classical caveats when it comes to the UNIBUS based system.
a) There must be an uninterrupted grant chain all the way and no holes.
b) There are two types of slots. DMA (also called a MUD or Modified
Unibus Device) and NON DMA. Default is non DMA. To enable DMA you cut a strap
on the wirewrapped backplane. (*cringe*)...
This suggests that there are also two types of GRANT cards. One resembling
a dual QBUS grant card but with green handles and one very small "playing
card type" single card with no handle that can be (with force) inserted
backwards and thus burn the bus.
c) There must be a terminator card in the last position of the chain.
I am at a customer site right now and do not have access to my library so
I can not be more specific.. If you have any documentation handy, you should
be able to use above information and find the exact information you need.
If not, you should be able to locate the faulting device by "shortening"
the bus. You start with CPU and a mem card and install the terminator
directly after. See if you can deposit and examine stuff into RAM. Then
put in the device directly after the last MEM card and test it and so forth.
Eventually the system will fail and you have located the problem.
Either remove the problem or get back to us. =)
Note: With no documentation of the devices in question you have more problems.
Some UNIBUSes are standard UNIBUSes. Others are special UNIBUSes for special
device configurations.
The UNIBUS PDP11 (or VAX) is a challange for the technically interested
person. =)
Oh yes... You can bypass devices by using the UNIBUS cable (a long stiff
white flat cable with UNIBUS connectors in each end). Each UNIBUS sub bus is
connected with the previous with a UNIBUS continuity card that consists of
a short UNIBUS cable and two dual cards joined together to form one unit.
If you want to bypass a device, take out the continuity from the start and
end of the device, install a UNIBUS cable at the last position of the
previous sub bus system and the first in the sub bus after the bypassed
device.
UNIBUS cables, continuity cards and grants (and also the terminator) all
go in the same position across the bus and in no other place.
One error here and it is BURN baby BURN! =/

Kermit would be running under RT-11 the all I'd be doing is copying a
tar.z file over or make the detar'd files over to files under rt-11
structures. I need more on genning a bootable image from RT-11.
While I'm comfortable in a lot of systems unix generally is not one
save for user level activity.
The only unix I have running currently is xenix on pro350 and linix
on PC. I can't say how useful either would be to this project.

Hi dear PUPS!
It is about one week gone from the mome I got
sufficiently powerful PDP-11. Before this I ran LSI-11/02 under RT-11
and couldn't think about unix. Those new machine is the
main reason for joining to this list for me.
It includes: KDF-11 CPU, RQDX3, DHQ11 8 line async option,
TQK70 tape controller, 1.5Mbyte of memory etc. etc.
I also have the complete BSD2.9 source distribution
in tar file and like to run all of the above.
Currently I've started KDF11 and it seems to be ok.
Problems are: It has lots of switches (the same for MSV-11 boards and
RQDX3 and all of that) and have very little docs about
how to set it correctly. When I tried to bring up the KDF with memory
at once KDF said : no memory :-] but it runs ok with
little 32K memory board from LSI-11/2 ! Seems to me that my MSV-11 boards
have wrong starting address settings or something...
Same story with RQDX3 - currently I have no RDx disks so I thought
that boot my system from RX50 is not a bad idea... I've plugged
standard 5 inch floppy to RQDX3 sig. dist. connector labeled "RX50"
and fired up the machine. Got nothing. I tried to investigate
what happens to bootstrap. I've detected that during init of
mscp controller it successfully undergoes steps 1 and 2 ( or maybe even 3)
but in next step it returns 0 in SA and bootstrap waits for eternity
when controller will enter next step... Looks like hardware fault, ha?
Then I tried to check my TQK70 board. It had nothing connected to it,
and I traced it's initialization sequence the same way. IT ALSO RETURNS ZERO
in 3rd or 4th init step!. Can anyone help with the above?
Sincerely yours - Stacy.
