Hello,
I am getting the following error when I try to boot my PDP. The Card
details for the CPU and the Memory Board are as under.
Here are the details of the Various cards.
Slot 1(ABCD) KDJ11-BB (M8190)
Slot 2(ABCD) MSV11-QA(M7551)
Slot 3 (AB) M3107
Slot 3 (CD) Blank
Slot 4 (AB) Solna prinitng machine card
Slot 4 (CD) BIT Scandiavia card
Slot 5 (AB) Blank
Slot 5 (CD) M7555
Can some one please guide what I can do besides replacing the old card
with a new card.
Regards,
Shroff

Ah ha! For moving filesystems dump+restor or 'afio' need to be
used. Dump+restor also have the advantage of preserving the
file flags (see chflags(2) and chflags(1)) - other utilities do
not preserve that metadata.
The other thing that dump+restor (or afio) handle correctly is
the special files in /dev. 'tar' does not know how to archive
files such as "/dev/rp0a".
Mmmm, I wonder if the problems you were having were caused by
/dev not being correctly populated.

Yes, they do look (more than a little bit) strange.
On my system here (a P11 based emulated PDP-11 - I have a real 11/73
but it is only powered up when I'm actively testing):
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/xp0a 8228 3163 5065 38% /
/dev/xp0h 155328 84188 71140 54% /usr
What patchlevel did you mention the system was at? There were a lot
of patches issued after the ' 2.11_rp_unknown' image was created.
One thing, which probably will not make any difference, to try would
be to recompile 'df' (and possibly 'libc') and see if the problem
changes. Looks like it's a math error of some kind so either
the compiler/libraries are broken or P11's having a problem doing
arithmetic.

This didn't work either.

No, tar. I tried again with dump and restor and now it works! Thanks
for the hint! I seldomly use dump/restore.
Now there's enough space in /:
$ df

Btw, the capacity values look a bit strange?

It might be necessary to use the '-s' option . "fsck -s" will
unconditionally rebuild the freelist.

Did you use dump+restor?

The boot block, /boot, /unix, /netnix and /etc/init, /bin/sh are
intact since the system got as far as printing the memory numbers.
After the memory stats the '/etc/autoconfig' process should be
run ('init' runs it) and the device probes should take place.
The only thing I can think of (and it's a wild guess) is that the
"clock" isn't running - thru the boot process clock interrupts
aren't used but when 'init' goes to run 'autoconfig' the system nees
clock interrupts in order to drive the context switching. Either
the clock isn't running or /etc/autoconfig got corrupted somehow
in the copying.

Yes, but it didn't help :-(
What can this be?
I tried something else, I copied the contents of the root fs
elsewhere, newfs'd the root partition and copied the contents back.
But now booting stops when it normally starts init,

I post this message with hope that someone out there can help me with a
problem I have at hand.
My company recently bought a preowned printing machine, which uses a
PDP11/73 BA23
connected to a VT240 terminal to control the functions of the machine.
Needless to say that we are unable to make the PDP run since we have no
knowledge of the machine and have no one to look upto for guidance..
While we are able to power on the PDP, the VT240 is dead.
Looking for help I came across your site and got the feeling that you
might be able to help me out of my current deliema.
While I have the original program disks, I have NO operating disks or
knowledge of what OS is on the PDP. The printing machine is controlled
by the PDP thru 4 serial ports (TT0 thru
TT3), the machine has a total of 8 ports, 4 are left unused.
PLEASE HELP.

Shroff

It might be a corrupt freelist. If that is the case then running
fsck will detect that fact and reclaim the space by rebuilding the
freelist.
> Where is the missing space?
My guess is it's "missing" - that can happen if the system's shutdown
(or the emulator terminated) prematurely. In that case the freelist
metadata might not have been updated.
I see Greg mentioned running fsck. That sounds like an excellent
suggestion.

Hi,
I'm running above image with the p11 emulator, and the root partition
is almost full.
I tried to clean it up, but I cannot find where the space is used.
df says:
--------
# df
Filesystem 1K-blocks Used Avail Capacity Mounted on
root 7816 7030 786 10% /
--------
but looking at files, I only see 2MB+ in use:
--------
# du -s /
2702
--------
This persists over reboots, so it doesn't seem to be a large deleted
file which is still in use.
Where is the missing space?

chris

I've just sent some mail to Tim Shoppa, asking if he would be willing
to read the tapes for us.

Hi,
I've been lurking here for a week or two, reading the
archives on porting v7 to x86, etc.
On a lark, I downloaded the v7 sources and started to
"upgrade" them so the userland can build and run on top
of modern OS kernels such as Linux. The bulk of libc
is the same (warts and all), with the "sys" layer replaced
with modern syscalls.
Perhaps it is a bit "sacrilegious", but I believe it makes
the code more accessible for experimentation, and it
should solve the "how do we get a PDP-11 compiler"
problem: we use the original hosted on top of a modern
kernel as a cross-compiler.
Check it out and let me know what you think. Most of
the libraries have been upgraded, with a handful of the
simpler command-line utilities.

Cheers,
Rhys.
