I don't know what the problem with Ultrix is but I suspect
your trouble with System-III is similar to what I wasted a couple
days on eons ago
Spent a fruitless couple days trying to get Sys-III going on a 11/44
only to have it dawn on me that Sys-III didn't have *any* UMR support
except for the DH-11 - thus an 11/70 with MASSBUS devices was the
only thing Sys-III would run on.
As far as I know no effort was put into Sys-III to deal with 22
bit machines that didn't have a MASSBUS (a la 11/70). PERHAPS
that is what is biting you? Feels likely. I know that no effort
was put in to supporting UMRs on 22bit systems such as the 11/44.
The Supnik and Begemot emulators offer up a ~kdj-11 (11/53, 73, ...)
and not an 11/70 so it could be that Sys-III is trying to do
something 11/70'ish that KDJ-11 based systems don't offer.

Hi ,
Im interested in a PDP-11 assembler that has the MACRO-11 syntax,
I got a book, "Introduction to Computer Systems using the PDP-11 and
Pascal" by McEwans, Thought it would be nice to have the assembler to
check out. I hope the assembler is a load and go assembler cum simulator.
I want to check out some PDP-11 assembly on my linux machine.
Does anyone remember a program called "apout" I think that might work for
cross development (learning).
Bye

Yes, I wrote Apout. It runs user-mode programs from V5, V6, V7, 2.9BSD
and 2.11BSD. So if you could find an assembler for any of these systems
which met your requirements, and produced .o files which could be linked
using the normal Unix linker, you'd be okay.
However, I haven't heard of a Unix assembler with MACRO-11 syntax, and
Apout only runs PDP-11 Unix binaries. So you probably would be better
off with a full emulator running a DEC OS with MACRO-11.
Cheers,
Warren

Has anyone successfully booted either the System III
(...Distributions/usdl/SysIII/) or Ultrix (...Distritutions/dec/Ultrix*)
tape images? I don't have a real PDP-11 any more, however both the
Begemot P11 and the Supnik emulators produce the following on a
generated boot disk:
#0=unixhptm
ka6 = 1535
aps = 141774
pc = 1476 ps = 30010
trap type 0
ka6 = 1535
aps = 141666
pc = 113444 ps = 30300
trap type 0
panic: trap
The Ultrix images both fail to actually boot from tape, as they
quit after reading the first boot block. Thus I am unable get as
far as being able to generate a disk image for booting.
I'm somewhat confident that my tape image booting and system generation
procedures used with the Supnik emulator are working properly, since I
successfully generate disk systems from both the V7 (Bostic) and
the 2.11BSD boot-tape images.
Any info and interest of others gleefully appreciated :)

Hi.
I have been given a Bull DSP 2/300 system. The machine is running B.O.S.
version 02.00.12. The machine boots and runs fine and I cal login as Root
and look around the system. The problem I have is that the B.O.S. operating
system is a Unix look-a-like and I can find no-one who actually knows
anything about the box. Most Unix commands work but, being a VMS guy, I
can't run the machine like my Digital MV 2's. Does anyone know anything
about these machines? I particularly want to have a bash at programming the
machine. It appears to have C (This should be fun. I've not touched C for 12
years!)
Also. I have two Digital Micro Vax 2's. The both have hardware problems in
that a) One machine has a system disk which will not come up to speed and b)
The other has a corrupted system_primitives.exe on VMS 5.5-H and so I can't
run either of them! Anyone know where I can get spares which are pre-loaded?
I really would appreciate any help or advice/ pointers etc that anyone can
give.

Hmm.. I seem to remember, from when I was thinking about rolling my own
11 OS a few years ago, that the /34 differs from most of the other
mid-range
11s in automatically restoring the CPU registers on a page fault. I
think I
picked this up from the differences table in the /04, /34 & /60 CPU
handbook.
(This was unfortunately no use at all to me, as I've got a /40 not a
/34.)
Of course, that was a while ago and I might be wrong.

It's not the automatically restoring that is the problem - the /34, /40
(/60, etc) lack the MMU registers that record by how much the cpu
registers have incremented/decremented at the time an instruction has
faulted. SSR1 and SSR2 located at 0177574 and 0177576 respectively.
From the module which handles the instruction restart (mch_backup.s):
* 11/40 version of backup, for use with no SSR1 and SSR2. Actually SSR1
* usually exists for all processors except the '34 and '40 but always
* reads as zero on those without separate I&D ...
What is a dozen lines of code if those registers exist turns into
over 300 lines and even then there is no guarantee (fortunately the
C compiler does not generate the sequences that can not be handled)
it will work.
What's instruction restart used for? The most common case is growing
the stack. The stack for a process starts out small and then kernel
will automatically extend it downwards IF an instruction faults when
accessing the stack area:
sub $N,sp
mov $xxx, XX(sp)
mov -(r4), X(sp)
for dealing with local variables in a function. The other case
is when calling a function:
mov (r0)+, -(sp)
mov $xxx, -(sp)
jsr pc, function
If the reference to (sp) is made and the instruction faults the
kernel will determine if the current stack needs to be extended. It
will then restart the faulted instruction - but to do that it needs
to know what other registers ('r0', 'r4', etc...) might have been
already changed so that it can back out those changes before
restarting the instruction.
In the case of the 11/44, 70, 73, etc there are MMU registers that
will record the fact that "R0" or "r4" or whatever was changed by
2 or not. On the /34 and /40 that capability does not exist and
the kernel can not _always_ guarantee things will work. MOST of the
time it will but...
Interestingly enough there is a difference between the KDJ-11 (11/73)
family and the other 11s which have the SSR1, and 2. From the
bug report and fix for 2.11BSD (update #150):
"The problem is that the KDJ-11 processes the double word store
of the 'movfi' differently than the 11/44 or 11/70. On other
systems (such as the 11/44) the first word is stored successfully
at 0175000 then the program faults when trying to access 0174776
but SP is left at 0174776 with SSR1 (memory management
status register 1) indicating that 'sp' was decremented by 4. The
kernel adjusts 'sp', grows the stack and restarts the instruction.
The 'movfi' then completes successfully.
On a KDJ-11 cpu the story is different. The fault is generated
as expected BUT 'SP' IS STILL 0175002! The kernel sees that 'sp'
is still within the "valid stack region" and DOES NOT grow the
stack at all. SSR1 indicates that no registers were modified
so the kernel does no adjustment of 'sp'. The instruction is
NOT restarted and a SIGSEGV signal is sent to the program.
The problem appears to be only when doing FP instructions, fixed point
operations do not experience any difficulty. The instruction
"cmp -(sp),-(sp)" for example is handled correctly."

I _think_ I know what the problem is...
While the /34 (and /40, etc) can run a stripped down V7 (the necessary
mch.s code exists for example) the kernels that come with the
distribution are split I&D kernels. /hptmunix, etc are all split I/D
executables. Thus you'll be able to toggle in the bootstrap and
get /boot loaded but then fault when loading and/or trying to execute
the kernel.
As I recall the usual way to get Unix on to a /23, 34,etc was to
have a 11/70 around to do the build on, then stage/create the media
(usually an RL02 or similar) on the 70 and sneakernet the pack over
to the /34.
At least that is how it was done when we shoehorned V7 into an 11/23.
Of course we "cheated" in that we had a fellow around who made the
necessary changes to the assembler/compiler/linker to handle kernel
overlays (preceeded the use of them in 2BSD by several years). Thus
we could run a larger kernel than a pure/stock V7. It was an
"interesting" experience running V7 on an 11/23 (maxed out with 248kb
of memory which was fairly expensive at the time). There was just
enough memory left after the kernel was loaded for a couple user
processes. Thus as the '#' prompt you would run "ls" the shell ('sh')
would get swapped out, the 'ls' would run, and then 'sh' would get
swapped back in. Uh, slowed things down just a _little_ bit :-)

I'm 99% sure, that it's V7 which I have running (for lower values
of running, because one drive is dead and the power supply needs
to be replaced) on my 11/34A with 128kB RAM and two RL01. I think
I wanted to install V6, but installed V7 because of the RL01 drivers.
I stripped V7 down, so I only needed one RL01 disk pack (I have only
two.) and transfered the disk image via kermit.
I want to install 2.11BSD on my M70 with 512kB RAM (No, more RAM is
to expensive here. 1MB for over US$500.) and a 120MB ST506-type disk,
but had not much time. I want to avoid the way of the disk image,
because I have no BSD installed for the emulator and don't know,
if the transfere of slices of the disk image would be successfull.
(The RT-11 only handles 32MB "disks".) I think the best way would
be to boot from a 2.11BSD floppy and install it via serial port.
(TU-58 emu? Are there 1.2MB 2.11BSD floppies somewhere?)

Sorry for the delay Kirk. It could be that the V7 bootstrap expects
split I/D, or a different I/O mapping then what's provided on the /34.
I'll punt this to the PUPS mailing list. I have a suspicion that
you won't be able to install V7, but you should be able to install V6
or 2.9BSD instead.
Cheers,

I once had Ultrix-11 3.1 running on a dual RK05 11/34. What I'd call a
very minimal system ;-) But it ran

Hi -

I will be doing some more research on this when I get home from
work tonight.

That is because DEC put the extra effort into supporting non-split I/D
machines. The "stock" V7 really wanted a 11/70. In fact there was a
chapter in the back of one of the manuals/books detailing what it took
to get V7 running on an 11/40 (it was a non-trivial project).
Several things conspire against V7 and later on 11/34 (or 35, 40, 60,
etc). The two most notable ones are the limited address space,
everything (drivers, data structures, general kernel code) must fit
in 56kb instead of 120kb - (8kb reserved for the I/O page) and lack
of instruction restart on MMU faults.
I'll take a look at the V7 layout later but my memory is that it
wanted an 11/70.

Here's the policy for the machine holding the PUPS Archive:
+ People with UNIX source licenses can get at least
guest FTP access to the archive, with S/Key as the
authentication mechanism.
+ People with UNIX source licenses, and who either
help to maintain the archive, or who have volunteered
to distribute the archive, can get ssh access to the
machine.
+ No telnet access, no e-mail. The box runs with `reserved
tolerance' from the real system administrators :-)
If you fall into either category, and can prove you have a UNIX source
license, then I can either PGP e-mail you, or fax you, the access
details.
Apologies for the cross-post to the 3 old UNIX-related mailing lists!
Cheers,
Warren

Actually, your email made me think: if I collect _erverything_ offered to
me, then I _will_ run out of room soon.
So, how about the idea of a register? You tell me what you have & your
contact details. I put up a web page with the stuff, your name, and
your contact details if you are happy.
Then, if people want access to them, they can contact you. Or, if you'd
rather not have your contact details on the web, they can contact me.
And if you feel like getting rid of them, you can email me and I'll see
if anybody wants them.
Let me know what you think. P.S I'm cc'ing this to the PUPS mail list
for similar comments.
Cheers,
Warren
