[pups] Fwd: Re: Concurrent Pascal, Solo OS, et al

by Wesley Parish

I asked Per Brinch Hansen recently about Solo and Concurrent Pascal, for use on the PDP 11 simulators, et al, and I received a reply today. This is it. I am wondering, does anyone have any clue as to where these copies of the system might be squirrelled away? How many might've seen it at their Universities?

At Caltech we prepared a distribution tape for the PDP 11/45 with the source text and portable code of the Solo system, including the Concurrent and Sequential Pascal compiler. The system reports were supplemented by implementation notes. By the spring of 1976 we had distributed the system to 75 companies and 100 universities in 21 countries. Later, other people moved the system to the Interdata 8/32, NCR 8250, Modular 1, LSI 11, IBM 370/145 and many other computers. Sad to say, I no longer have a copy of the system (and I don't know who does). Per Brinch Hansen ------------------------------------------------------- -- Mau e ki, "He aha te mea nui?"

Looking for obscure unix information

by Apostolos Koutropoulos

Hi to all, I stumbled on your mailing list and I thought this would be a good place to pose my question. I was looking around for information about several little known (to me) unix derived Oses. AMIX (Amiga Unix) RISCiX ArchBSD Lynx Inferno Helios What I am looking for is basically what versions existed and when they were released, and also from where did they originate. For instance I know that RISCiX originated from BSD 4.4 but that is all I know. I also know that inferno grew out of the research for plan 9, but what version of plan 9 it evolved from I don¹t know. Anyone know the above info? If not any idea where I can look for further info? Thanks :)

[pups] Tektronix 8560 with PDP-11/23 CPU running TNIX (UINX)

by Jochen Kunz

Hi. I got a "Tektronix 8560 Multi-User Software Development Unit" together with a Tektronix 8540 in system 68k CPU emulator. The 8560 is based on the DEC M8186 PDP-11/23 CPU module but that card is the one and only DEC part in the machine. Everything else is from Tektronix. There is a 35 MB 8" disk and a 8" floppy in the 8560 and it runs some flavor of UNIX called TNIX. I am trying to break into it currently, as I have no passwords. I can't get it to single user mode and I have no distribution media nor no stand alone tools. Has someone heared from this machine bevore? Has someone distribution media or stand alone tools? -- tschüß, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

RE: [pups] Restoring volumes

by Gregg C Levine

Hello again from Gregg C Levine Yes, Ian. That's exactly what I mean. Of course I was thinking of RL02 images, rather then a RK05 image. Which one did you choose? And can you post something explaining the steps? And your response was the simpler form, which is what I wanted. David's comment was a bit obtuse, but I got it. By the way? Are you a WB fan?

I don't remember the details in my head and I'm also typing this on the go, but in 4.3BSD fsck does work on the block device and then you reboot with, well, reboot, and it works. MS

Re: Re: [pups] 2.11BSD device config trouble

by Norman Wilson

Carl Lowenstein: Isn't this really true of Unix systems of any age, when doing fsck on a mounted root file system? Some middle-elderly BSD systems--4.1 and possibly 4.0-- managed the buffer pool in such a way that the super-block of a mounted file system was kept in the original buffer, with device and block number correctly stored in the struct buf header. Hence if fsck wrote to the block device rather than the raw one, the super-block came out right even when checking a mounted file system; in particular there was no need to reboot. This convenience was abolished in either 4.2 or 4.3 (I am travelling right now and cannot check manuals and sources). I never quite understood why, though I never looked at the source code in the later systems. The scheme found in most current systems, in which the root starts out read-only, is a better idea anyway.

[pups] Restoring volumes

by Gregg C Levine

Hello again from Gregg C Levine Just for the sake of an argument, has anyone actually managed to restore a volume from the collection on the ftp server, back to an originally sized disk pack? Or for that matter restored a system so that it behaves as advertised under E-11? No, folks that machine I "have on order", has not arrived. Once again I am searching for information for a future project. One that might be happening sometime this week, or even later this month. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

Yes, it does. A bug in the parsing. Why it does not affect all the lines is unknown. Perhaps some trailing whitespace caused the parser to exhibit the bug. > But if I try to use /dev/ttyl1 I get a message about a unknown interrupt > and the output of /dev/ttyl1 hangs after the first character. What is the exact message? I did a "strings /unix" and could not not find a string that looked mentioned unknown or interrupt. That would seem to indicate that the device is interrupting but not at the expected vector. It is possible to use 'adb' to look at the contents of the vectors. adb -k /unix /dev/kmem 0344/o will show the contents of the 0344 vector. The value there should be equal to 'cnrint' (or cnxint - I forget which comes first). > I have a M3106 DZQ11 that I can use instead.

I am really not used to Unix stuff of that age. :) I did the the same thing - wondered why I could never get a clean file system. Then I realized what was going on. Cheers, Steven Schultz

Newer systems mount the root filesystem read-only while running fsck. After the filesystem is verified as clean then it is upgraded to read-write. Older systems such as 2BSD can't run with a read-only root filesystem that I know of. At least not easily/happily. Might be possible (the ability to upgrade a ro mount to rw is present) but it's never been a priority to look into it ;) Cheers, Steven Schultz
