That sounds like an excellent > suggestion. 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, ------------- : unix Boot: bootdev=05010 bootcsr=0176700 2.11 BSD UNIX #1: Fri Feb 15 18:47:18 PST 2002 chris@pdp11:/usr/src/sys/PDP11CPG attaching qe0 csr 174440 qe0: DEC DEQNA addr 08:00:2b:07:82:6c attaching lo0 phys mem = 2097152 avail mem = 1647872 user mem = 307200 ------------- ... and here it hangs. Do I have to consider something else when I newfs the root partition? regards, chris

[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

I don't think it's been well tested, but support exists in current versions of binutils and gcc. http://pdp11.nocrew.org/ there's also support for the m68hc11/12 which are 16-bit. it seems like support for 80{,1,2}86 in gcc should be possible; it just hasn't been done yet. another compiler that might be worth looking at is SDCC http://sdcc.sourceforge.net/ which is currently targeted towards 8-bit MCUs. of course bootstrapping via the original K&R compiler would be the "classic" way to do it, though. ;) -- Aaron J.
