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 Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/xp0a 7816 2658 5158 04% / /dev/xp0g 151625 117599 34026 08% /usr $ Btw, the capacity values look a bit strange? regards, chris

Do I have to consider something else when I > newfs the root partition? 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. Steven Schultz sms(a)2bsd.com

[pups] PDP 11

by Nutech

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. Regards, Shroff repro(a)nutechgroup.net

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. Cheers, Steven Schultz sms(a)2bsd.com

[pups] missing space in 2.11_rp_unknown

by Christian Groessler

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? regards, chris

v7 upgrade

by Rhys Weatherley

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. http://www.southern-storm.com.au/v7upgrade.html Cheers, Rhys.

Legal ramifications putting certain things on my web site?

by Derrik Walker v2.0

I've started porting some of the old UNIX programs to Mac OS X. I've got about 1/2 the games, that should be ok, but I also have other things like crypt and makekey. I'd like to make these available in binary form, but I don't want the men in black knocking at my door either... Any thoughts? On a side note, I simply can not believe how easy it is to compile this old code under Mac OS X. for some of it, it's proving easier than porting Linux code ( if you've only known how long I worked on linux's fortune, and the old one just compiled no fuss, no problems ). Also, if your wandering why ... that's easy, because I can. Thanks. - Derrik firebug(a)apk.net http://junior.apk.net/~firebug --------------------------------------------------------------------------------------------------- The number of UNIX installations has grown to 10, with more expected. -- The Unix Programmer's Manual, 2nd Edition, June 1972
