It should print the unlabeled diagnostic, but then proceed rather than fail. I just double-checked the standalone driver source, and it does provide a default label for RA82, as long as the MSCP controller actually returns RA82 as the MSCP disk ID. Does it give you an error message about disk type (some hex humber) not supported? If so, SIMH's MSCP emulation must be lacking in quality. > If only ra0 is > configured for simh, it takes the kernel a long time to decide that ra1, > ra2, and ra3 are offline.

Well, obviously this doesn't happen on real HW, since on real HW it works (I'm typing this message on a MicroVAX 3+ running 4.3BSD-Quasijarus). But I will grant the possibility that the kernel is not w/o fault either in that perhaps it's going south (dereferencing a garbage pointer and crashing) when the MSCP controller (in this case SIMH's poor emulation) is doing something it doesn't expect. If this is so, it should be fixed, since even w/o emulators (which I refuse to support on principle) real HW can be broken and return garbage on reg reads, and the kernel must handle it gracefully. I'll look into it. MS

Hello (again) from Gregg C Levine The RPM file provided didn't build correctly. Remember I did say that I use Slackware. I don't have a running instance of Red Hat here. However, I was able to build a copy of SIMH straight from the current source code. One thing does get to me, though. This creation moves a lot slower on SIMH/VAX, then NetBSD, which worked well enough. I'm guessing that this is indeed a populated pack you have here, but do you have any idea as to why it's practically moving slower then a tortoise? This is running on a Pentium 100. As to your question, yes they are working on it, moving through the 2.4.2x series of kernels. It isn't pretty, but it is working. If you want to join the list to offer complements, or comments, or just lurk, go to their website, and tell the list-manager that I sent you. He'll give you a good seat. ------------------- Gregg C Levine hansolofalcon(a)worldnet.att.net ------------------------------------------------------------ "The Force will be with you...Always."

Re: 4.3 BSD version in the Unix Archive

by Joseph F. Young

From my experience, you need to have a recent release of SIMH in order to run 4.3BSD. A few months ago, I managed to build "working" Quasijarus and Reno disk images (Quasijarus appears to work fine for me, but Reno is as buggy as I remember it being on real hardware). I had to use Ultrix and Netbsd to do the bootstrap/install; I could not get the tape boot to work at all. Here's my SIMH ini file for Quasijarus: --------------------------------------------------------------------------------------------------------------- set cpu 32m set cpu conhalt set tto 7b set tti 7b at rom ka655.bin at nvr nvr.bin set rq0 ra82 at rq0 bsd43q_ra0.dsk set rq1 ra82 at rq1 /dev/null set rq2 ra82 at rq2 /dev/null set rq3 ra82 at rq3 /dev/null set tq0 locked at tq0 BSD43Q_TAPE.tap set dz 7b at -m dz0 4501 at xq eth0 set lpt dis set ts dis set rl dis boot cpu -------------------------------------------------------------------------------------------------------------- Here's an example boot log for Quasijarus under SIMH: >>>boot dua0 (BOOT/R5:0 DUA0 2.. -DUA0 1..0.. loading boot Boot : /vmunix 327204+103384+130352 start 0x23a8 4.3 BSD Quasijarus UNIX #0: Sat Oct 2 22:15:38 CDT 1999 msokolov@luthien:/usr/src/sys/GENERIC real mem = 33521664 SYSPTSIZE limits number of buffers to 80 avail mem = 31697920 using 80 buffers containing 655360 bytes of memory MicroVAX 3000, ucode rev 6 tmscp0 at uba0 csr 174500 vec 774, ipl 15 tms0 at tmscp0 slave 0 tms1 at tmscp0 slave 1 uda0 at uba0 csr 172150 vec 770, ipl 15 uda0: version 3 model 3 uda0: DMA burst size set to 4 ra0 at uda0 slave 0: RA82, size = 1216665 sectors ra1 at uda0 slave 1: no disk label: ra82, size = 1216665 sectors ra2 at uda0 slave 2: no disk label: ra82, size = 1216665 sectors ra3 at uda0 slave 3: no disk label: ra82, size = 1216665 sectors dz0 at uba0 csr 160100 vec 300, ipl 15 dz1 at uba0 csr 160110 vec 310, ipl 15 dz2 at uba0 csr 160120 vec 320, ipl 15 dz3 at uba0 csr 160130 vec 330, ipl 15 qe0 at uba0 csr 174440 vec 764, ipl 15 qe0: delqa, hardware address 08:00:2b:aa:bb:cc Changing root device to ra0a WARNING: clock gained 91 days -- CHECK AND RESET THE DATE!

Of course, it may well be that applying a hex editor to the disk > image will suffice. Arghh, why don't people just f-ing get it! Standalone format is what is known as low-level format in the PeeCee world (magnetic level stuff, certainly not needed on an emulator), and it has absolutely nothing to do with disk labeling. 4.3BSD-Quasijarus0[a] does not have standalone disklabel, but RA82 is known to the compiled-in tables and thus will work unlabeled. Also Ultrix' disk labels are not useful for 4.3BSD-Tahoe/Quasijarus, since the labels are stored in a different place in a different format. (Berkeley and DEC developed pack labels independently. BSD stores them in the boot block, Ultrix stores them in the root fs superblock, which has the disadvantage of requiring you to create some dummy root fs before you can write a label, even if you want a root fs of different size.) > Am I correct that Quasijarus supports RA82 disks (using the ra type) and the > TK50 tape (as a tms)?

Any unix for MicroPDP-11?

by Matthew E Hoskins

Greetings all, and forgive me if this was answered prevously, but i didnt see it when i grepped the archive.. Are there any *nix versions in the archive that will run on a MicroPDP11 model 630QZ-AX? Currently it is running RSX-11 /w what looks like a seagate MFM/RLL type HDD. It has only dual floppy for removeable. But i might be able to get my hands on a TK50/70 and qbus adapter for it.

Michael > Sokolov should be able to send in some notes on the tools required. Yes, for political reasons I needed to make the 4.3BSD-Quasijarus compressor a version of compress, not gzip (can't have any GNU), but I wanted to have the higher compression ratio of deflation, so I created a new version of compress that supports deflation in addition to the original LZW algorith. You can find the new compress in components/compress.tar either on my FTP site or in Warren's archive in the 4BSD area. > > Is there a set of 4.3BSD-Tahoe Vax distribution files that's complete? > > Not that I know of. "4.3BSD-Tahoe Vax distribution" is an oxymoron. Berkeley released the Tahoe tape with Tahoe binaries, no VAX binaries. I was the one who compiled the Tahoe source for the VAX, and the result was 4.3BSD-Quasijarus0. OTOH, you may be referring to the fact that the Tahoe distribution in the archive is broken. Yes, it is. Unfortunately there was an unrecoverable tape read error. > > Finally, do you know of any 4.3BSD version that will install and run on > > simh?

ctcompare 1.2 is up

by Warren Toomey

Hi all, It's probably bad form to release a new version of a program 24 hours after the last version, but version 1.2 of my C comparison tool is now available at http://minnie.tuhs.org/Programs/Ctcompare. The speed has been vastly improved by using the Rabin-Karp string comparison algorithm, and thanks go to Roger Willcocks who pointed me at the algorithm. There are no other bug fixes, and I shouldn't bring out a new version for quite a while now. So if you have access to any restricted C source trees, maybe you can send me the ctf file of the tree so I can do some comparisons! Cheers, Warren

All identifiers, (variable names) are reduced to a single token. Actually, that's not true. The meaning of the names is removed an replaced with numeric identifiers that are unique to each file.
