I've assembled some notes from old manuals and other sources on the formats used for on-disk file systems through the Seventh Edition: http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html Additional notes, comments on style, and whatnot are welcome. (It may be sensible to send anything in the last two categories directly to me, rather than to the whole list.)

What to look for in a PDP machine?

by rdkeys＠unity.ncsu.edu

Interesting, there may be a PDPsomethingorother machine come available in surplus here. A quick glance at it showed it to be in a 1/2 height rack, with some custom name that meant nothing to me. But, it had two rack cabinets about 6 inches high each, with definite looking DEC cards, 4 wide cards, with an interconnecting cable between the two cases. The thing had a half gig scsi drive and scsi tape (60 or 150mb). Alas, I was able only to make a quick glance at it, before I had to leave. What might such a critter actually be? It had half a dozen RS232 terminal lines out the back, and a wyse terminal sitting on top of the case. It is not the kind of thing the PeeCee mongers are going to dive into, so it might go for a song if I wait a couple of weeks. It was not DEC badged, but definitely had what I would interpret as DEC boards inside. Bob

Why mix-and-match the wonderful classical hardware with > crappy bloated "modern" software? This list is definitely geared towards people running classic OSes on classic systems. I actually really enjoy having lots of the bloated modern hardware running on my VAXen. So much contemporary software compiles and runs right out of the tarballs under NetBSD/vax. And honestly, a lot of it performs quite admirably on even my humblest of MicroVAX II's. I see nothing incompatible with loving modern OSes running well on ancient hardware. :-) -brian. --- Brian Chase | bdc(a)world.std.com | http://world.std.com/~bdc/ ----- All math equations have a fistfight on at least one side. -- K.

Yes, it will run UNIX, the timesharing system by Ritchie and Thompson, Berkeley VAX version thereof, the current version of which is 4.3BSD-Quasijarus maintained by me, the WWW page for which is: http://minnie.cs.adfa.edu.au/ Running UNIX requires a UNIX source license (True UNIX never had, doesn't have, and never will have a concept of "binary only"), but these days SCO gives them out for FREE! You have a tape drive, so you will have no problem with installation. I have supply you with the boot tape, but you'll have to reimburse me for the tape and shipping. > How do I hook up the Console to work on it. For that matter, what does > the console look like? You need a standard RS-232 terminal. The console port connector on the MicroVAX is of a rather odd standard, though. A DEC BCC05 or BCC08 cable will connect it to a standard RS-232 DB25M terminal. If you want or have to make your own cable, I've got the pinout for the MicroVAX console port connector somewhere. > [...] nothing on 'where and > how the cables go on the back (bulkhead). The I/O distribution panel on the back provides external connections for all Q-bus modules you have. You'll have to tell us what Q-bus modules you have so that we can tell you what external connections they need. You obviously have the CPU, which has one external connection: the console port which I just told you about. > I need to know how, why and > when to turn the knobs on the back. On the CPU module bulkhead there are two knobs and one switch. One knob selects the console port baud rate. I think this one is obvious. You can use any of the baud rates printed around the knob, but 9600 baud is standard. The other knob selects between normal operation (the arrow icon), console language selection (the talking face icon), and console port loopback test (the T in the circle icon). I always leave it on the arrow icon. Finally, the switch selects between maintenance mode (halt enabled, stay in the console on power-up) and production mode (halt disabled, boot the OS on power-up). These correspond to the dot- inside-the-circle and dot-outside-the-circle icons, respectively. For now leave the dot inside the circle.

Yes. port-vax is the right audience. (I am part of it. ;-) ) There is an excellent site with information about VAX hardware. http://www.vaxarchive.org/hw/index.html mirror at http://vaxarchive.sevensages.org/hw/index.html There you can find a link to the KA630/MicroVAX II page http://www.telnet.hu/hamster/dr/ka630.html This will answer most of your questions.

Of course, since I don't have call waiting or voice mail, that is to be expected :) I've actually thought about trying to acquire an MSCP<->SCSI card and using one of the SCSI drives I have lying around, but the 19" rackmount stuff is too cool (unfortunately, my spares cabinet is full of dirty laundry and ruined CD-R media at the moment), though I suppose an RA92 would suffice (anybody got one? :) though my budget is henceforth nonexistant -- $300 wouldn't break the bank, because they wouldn't give it to me. Don't know about the RQDX3, either, but more likely the KDA50 (which drives my RA81 -- the RQDX3 is for RXen, no more). The '81 was up all last night, so I don't have error numbers yet; I'll try to repeat the RX50 problem sometime this weekend. The only FS, I have, is yours, though I've started reading through it. Though the SCSI spec is thousands of pages long, it's pretty easy to program; I just finished some raw-tape-read routines for Hewlett-Packard CS/80 tape drives, that was even simpler. In both cases, however, I do have documentation (exhaustive documentation in re: SCSI -- again, work related). I take it from your reply that such docs aren't to be had for MSCP? At any price?

You do not need to "reblock" the files - they already have the correct sizes. What you do need to do is run a program to add the record length information for the emulator. The emulator needs to have "virtual" file and record mark information added. If you look in the "usr/src/sys/pdpstand" directory you will find a source file "makesimtape.c". This is a slightly modified version of the 'maketape' program which 2.11 uses to create its own boot tapes. The modifications consist of changes to add the virtual tape marks for Bob's emulator. I will include a copy of makesimtape.c below in case anyone has trouble finding it in the source tree. makesimtape should compile on almost anything (I've used it on 2.11BSD, BSD/OS, and I think FreeBSD). Compile that program. Then create a small file (maketape.data) containing: mtboot 1 mtboot 1 boot 1 * 1 disklabel 2 * 1 mkfs 2 * 1 restor 2 * 1 icheck 2 * 1 root.dump 20 * 1 file6.tar 20 * 1 file7.tar 20 * 1 file8.tar 20 *1 Then "makesimtape -i maketape.data -o your_tape_file" will create the virtual tape file in 'your_tape_file'. Actually to make sure things work (and the tape is bootable and can run the standalone programs) all you need are the files up thru root.dump - that is enough to load the root filesystem. With a real tape drive you use the "maketape" program that comes with 2.11 of course since it wants to issue ioctl calls to place real tape marks, etc on a tape. > It's like the bootstrap code isn't working. Or possibly I've completely > misunderstood the proper way to build a tape image. Is there a better > way to go about it? Hopefully the method described above will be closer to what's needed. it has been quite a while since I've actually created a simulated tape so I might have left out a step or something. Good Luck!

Hello and thanks!

by Jason T. Miller

After about a week of work (mainly due to a dying RA81 ... see below), I have successfully installed 2.11BSD on my 11/83. First and foremost, thanks to a) Steven M. Shultz for so carefully maintaining and updating (!) CSRG's PDP-11 code to work with hardware such as my MSCP drives and TMSCP TK50 and b) everyone involved in prodding SCO to release free Ancient UNIX source licenses. After dealing with a crippled binary-only Micro/RSX lack-of-a-kit, and as a FreeBSD user of five-odd years, I decided to bite the bullet and see what UNIX was/is like on a PDP. Thanks to the work of Steven and a cast of thousands, it's pretty damned impressive. The only problems I've been having seem to be coming from disk controllers without media. More specifically, I get a hard error, followed by an endless loop of error indications if I try to access one of my RX50s (on an RQDX3 controller), and the only recourse is a reset. Okay, so the solution here is simple: don't do it. The bigger problem comes with my flake-job of an RA81, which, FWIW, is the only fixed disk storage I have. It has a strange habit: the "A" light goes off and the controller can no longer access it. If I soft-restart the PDP (under either RSX or UNIX), the driver connects back to the drive without a glitch. And this gives me the same loop-of-errors syndrome as an empty RX50. Anyone have any pointers or sage advice? I figured I may try to modify the MSCP driver to re-init the controller on a hard error, and try again. But the MSCP code is fairly complicated, and I know nothing of the protocol. Anyone have any MSCP documentation which I could beg, borrow, or steal? I'd give the specific error codes, but I haven't written any down yet and I'm at work. Also, I am willing to provide a Good Home for any 19" rackmount MSCP drives in the midwest. Let me rephrase that: any one or two; I have a one bedroom apartment, and I'm saving a bit of floorspace for a (yet to materialize) VAX. Also Qbus thinnet or SCSI would be nice, whilst on cloud 780...

Unfortunately, they're binary only and System-V based, so I can't just throw 'em in the archive. But when the game is up on the System-V codebase, I hope these CD-Rs are still around. They are: - SCO XENIX 286 2.2, complete OS with development system and text processing ([tn]roff, etc) - Microport System V/AT Development System (runtimes say both 1.3 and 2.3, development stuff says 1.3 - don't know, never booted this one) All the floppies read without errors, and I've actually booted and run the XENIX (used it for a tape conversion job a couple years ago) - works as long as you have a 5.25" floppy drive and reasonably old hardware - I ran it on a 386 but it doesn't grok VGA. Also, I have the ability to write TK50 tapes along with a wide range of other formats (my employer makes tape conversion equipment and software); no TK25 (unless the old IBM Tandberg VarBlock format is identical - don't know) or TK70, but just about anything else (need PDP UNIX on an HP 9144A cartridge tape; a) why? and b) I can help*!). I'd be happy to cut PDP UNIX tapes for media and shipping. Finally, anyone ever used the mtools package to read MS-DOS disks from an RX50 from a DEC Rainbow? I'm working on it (no Rainbow, but I've got a box that writes Rainbow disks) and I'd be glad to help anyone interested; I'm also working on R/W RX50 on FreeBSD. Jason T.

I've just have a Z8000 SystemIII system being donated. I'm happy to take donations, but they may not be moved into the main archive because I don't want to have my butt sued off.

Do you also have Harti Brandt's P11 ("Begemot") emulator? That is a _work of art_! Has an emulated DEQNA so you can place the "PDP-11" on a LAN, the timeskew problem has been fixed (the emulated pdp-11 keeps good time), and it also has a TOY clock now.

I've got the > eight bitplane graphics card and no terminal available. Two RD54s? At least one of them must be external then, as there's only room for one full-height device in the VS2K box itself. I'm going to assume that you have the standard DEC configuration with one RD54 internal and an expansion adapter (pizza box) at the bottom with the 2nd external RD54 connected to it. Hey, except for the lack of TK50Z, you've got pretty much the maximum configuration from DEC for VS2K: maximum memory, maximum number of disks of top-of-the-line type, expansion adapter, and top-of-the-line graphics card! On your expansion adapter, right next to the connector for the external RD54, you should see a 50-lead Amphenol (aka Centronics) SCSI connector. It is indeed real SCSI, but the boot ROM, VMS, and Ultrix only support one SCSI device on it, the TK50Z. > I also don't have a TK50 or any external storage, Note that if you can get hold of a TK50Z (a box just like your external RD54, but with a TK50 drive and a TK50-to-SCSI adapter inside), you can readily plug it into the connector I just described. I don't think a TK50Z would be that expensive. Here in Dallas, TX, USA I get bare TK50 drives for $75 apiece and TK50 drive + TQK50 controller (for Q-bus) pairs for $100 apiece, and I don't think a TK50Z would be much more expensive. > so it looks like I'll be netbooting.

If you have VMS running on one disk, you can use it to install Ultrix on the other.

Installing an OS on my little friendly VAX-11.

by Jeff Johnson

Hey guys. I've got a VAXstation 2000 with 12MB of RAM, and two RD54 drives, one of which is developing bad sectors (the secondary). I've got the eight bitplane graphics card and no terminal available. I'd really love to get a copy of Ultrix 4.2 installed on this machine, but from what I can tell it isn't available. I also don't have a TK50 or any external storage, so it looks like I'll be netbooting. The machine currently has OpenVMS 7.2 on it which I can re-license and get running if it would help for an install. I've had almost no success with NetBSD either. The only kernel that would boot was a 1.3 snapshot release. All of the 1.4 kernels crap out immediately upon booting, and nobodys seems to be able to help me. Also, if anyone has a source for additional expansion for this machine, I'd be grateful. Thanks very much for your time. I really want to get this machine up and running again. -- Jeffrey H.
