I've aquired a copy of each: MVII DIAG MAINT TK50 AQ-GM5AN-DN MV DIAG CUST TK50 AQ-GL5AP-DN I'm going to try using dd to generate an image for duplication tonight. If I can make a bootable duplicate from the image, and if there are no licensing issues, I'll make the images available. Any interest or comments? Doc

DEC RC25 docs

by broth＠heathers.stdio.com

Does anyone have hardware docs for a DEC RC25 dual drive? I just received a couple and was planning to install one of them in my 11/725 but the power connectors are different. Any help would be appreciated. I am also looking for a spare CPU set for an 11/34. I'll be out of town until Sun so thanks in advance. Brian.

Not with the boot tape, DEC has screwed that up (not supporting their supported hardware for the boot tape, duh!) The key to success really was SIMH. With SIMH I could install ULTRIX on an RA90 image. Then I simply ripped the "a" partition as a binary image (3.5 MB zipped) and moved it to the VAX 6000/VMS. The move was greatly helped by Brian Wheeler, who gave me an uVAX-II and Isildur, who gave me a TK50 for it. Although I found out a trick by which one can drive the console port of the VAX6000/VMS up to 38400 bps (simply boot the machine and VMS with NO terminal attached, not finding a signal, it bumps up the speed to 38400 and keeps it there. This allows moving 3.5 MB in a bit less than 30 minutes.) Then I simply copied that image onto the disk mounted /foreign, booted the disk and voila! First time I got it up I was so excited that I messed up the unit numbers and accidentially killed both my VMS 7.2 system and my new ULTRIX disk! Luckily I had a spare VMS 5.4 disk in reserve. In a way I'm happy I blew my VMS 7.2 disk, because its DU0 and that should become ULTRIX anyway. Now I don't need to think about backing the VMS stuff up any more! Folks, this feels sooooooo good. I have been muddling for almost one year for this moment! The next questions are, since Evi Nemeth et al. unfortunately neglect ULTRIX in their otherwise excellent book, where do I learn about such things as ULTRIX 4.5 kernel configuration? I need to build a custom kernel, but when I tried it with my 4.3 BSD knowledge of how this is done, it failed because it didn't find sources and stuff. Can someone give me a few hints? Do I have to manually copy the .o filed of the BINARY directory into my own kernel directory? There are a few options in the config file that I don't understand, is that described anywhere? Also, does anyone have experience actually building the 4.2 sources? My next steps are: - make custom ULTRIX 4.5 kernel - build the ULTRIX 4.2 system from sources - get the CI working to the MTI StingRay and the HSC90 - load a bunch of software, especially GNU stuff, gcc, emacs, bash, less ... - Install PostgreSQL - try building the JDK - get a VAX 6660 and hack support for it into ULTRIX 4.2 - load NetBSD sources and build as far as it gets and add support for XMI, KA64A, etc. and for the other machines, get the MFM drive for my uVAX formatted (need to produce a diagnostics tape for that.) Start up my VAX 11/780, turn it into a 785 and make a dual CPU machine from it. Install the PDP-8/A rack and make it going. Final question for today: is there a program that rips an exact tape image from a physical tape (TK70). I have that diagnostics tape on a TK70 but need to move it onto TK50. The TK50 drive is not happy on the TQK70 controller (or VMS isn't happy with it.) So, I need to make a binary image, move it to laptop, boot uVAX-II/NetBSD and write it on TK50. Thanks so much for all your help and advice without which I wouldn't even have started getting the VAX 6400 ins the first place, much less making it boot ULTRIX. -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

Disassembling a Vaxstation 2000

by groovelists＠yahoo.com

Afternoon, all! :) I've had a Vaxstation 2000 sitting around here for a bit, but I've just gotten around to tinkering with it. Alas, the poor fellow seems to have an ill hard drive. I've managed to get the case open, but... well, this is rather embarassing... I can't quite seem to figure out how to get the drive itself out. I don't believe it is open at the moment, but I think the layout inside is something like this : ____________________ ----Motherboard----- -------------------- PS | Floppy | RD32 HD ____________________ The drive is held in by at least a screw or two on the right-hand side - I can remove those, but it is still held in by another seeming inaccessible screw and / or the cabling hooked up to the back of it. Any help or recollections anyone might be able to provide would be very much appreciated! :) Thanks very much! Cheers, Andy __________________________________________________ Do You Yahoo!? Yahoo!

Configuring ULTRIX 4.x kernel (was: Re: VAX 6400 booting saga: SUCCESS!)

Well, yes except that it's binary only, which doesn't just work as expected. But I found out, /etc/doconfig is an interactive script that does all the magic for you. I hate to do this interactively, but at least it got me going. And it's a script, so it can be seen what it does (among others ln -s ing the BINARY/*.o files to MYKERNEL/.) But I noticed two other stange things: (1) The GENERIC kernel configuration is really neat, it just says things like (off the top of my head, don't blame me on detail errors) controller kdb50 at vaxbi? nexus? controller kdm70 at nexus? controller klesib1 at vaxbi? nexus? disk ra0 at mscp disk ra1 at mscp ... tape tms0 at mscp ... which indeed is very generic. On the other hand, the config file that doconfig builds for me is very different, having knowledge about every bit of bus, cables and unit numbers: controller kdb0 at vaxbi13 nexus3 controller uq4 at kdb50 disk ra8 at uq4 drive8 controller kdm70 at nexus11 controller uq24 at kdm70 vector uqintr disk ra0 at uq24 drive0 disk ra1 at uq24 drive1 ... controller klesib0 at vaxbi14 nexus3 controller uq22 at klesib0 vector uqintr tape tms0 at uq22 ... Why would I want to take the above kind of genericity away from and lock myself into a kernel that only works for a certain configuration of cards in slots, such that whenever I should swap a few cards, I have to boot from a reserve GENERIC kernel and rebuild? If ULTRIX can deal with "nexus?" "vaxbi?" and "mscp" kinds of generic designators, why would I, why would it want to use those overly specific ones? And what is 'uq' anyway? (2) The other little thing is that (a) ULTRIX is not Y2K complient: I haven't convinced date (or anything else) to accept a century for setting the clock and it insists on "02" being rounded up to 1970 :-). (b) I noticed the VAX 6000 has two or three AA batteries (rechargeables) in its console assembly, would they by any chance keep a real time clock running such that resetting the date isn't required all the time (yes I know about time and ntp but I don't have a reliably on machine at home nor a standing internet connection.) cheers, -Gunther - Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

MVII Diags Chapter 2

by doc＠mdrconsult.com

OK, Friends & Neighbors. First, I'm starting to think that the original tape is damaged. The cptape utility suggested by Jochen seems to be Doing The Right Thing, but gets errors. dd has no qualms at all as long as the TKZ50-GA is set to a variable blocksize, but errors out on file #7. If I set "conv=noerror" for dd to ignore read errors, it saws away forever at the same file. And, if I boot the uVAX from either the original or the one "probably good" copy [1], sometimes it sees the RD53 disks as RD51. Not consistently. When it does, it hangs solid on a custom format. I'll be putting the -GA on a VMS box this evening and try the VMSTPCE copy. It makes sense to make the tape in its native OS. [1] I did get a good set of files with the TUHS cptape. Problem is that AFAICT the partner program, maketape, only understands 512*N blocksizes. The diags tape has a lot of files in 80B blocks. The good copy was made with dd, setting blocksize file by file. 82 files, that is.... Anybody remember the Bash test statement for [ FILE <larger-than> FILE] ? It would come in REAL handy, and I'm having a brain-fart. Doc

by skate＠ao.net

I have the same hardware as on this message but again I no idea where to start. Can anyone help me/point me as to where to start so I can start experimenting with this box?. Freddy Zapata skate(a)ao.net

VT-320 Hack+Tip for Smokers

by ajp166＠bellatlantic.net

Ok, The LK201, 301 and 401 are interchangeable, regardless of the cpu used internally. There is NO VAX, Decmate, Pro version or rainbow version save for different colored key caps. I regually swap LKx01 where x={2,3,4} keyboards with any VAX, Decmate, VT220, 320, 330, 340, Pro3xx and friends. They all used the same cord set. I happen to prefer older LK201 for keyfeel, and later LK401s for the sculptured layout. The LK250 however is a TOTALLY different animal and uses different keycoding to be compatable with PCs or VAXmate (a sorta PC). There are several different cordsets for this one.

DEC RRD43 terminator

by alan.pearson＠cramer.com

Been googling for info on the DEC RRD43 CD drive with little success over the last couple of days. So, a couple of questions for the DEC gurus out there: Does anyone know what the various jumper settings are? I'm trying to work out how the thing is currently configured. There are two "centronics-style" connectors on the back. Do I need a terminator for one if the other's plugged into a VAXstation? What does it mean when the yellow LED flashes? At the moment I don't have a cable to hook it up so I switched it on standalone just to see what happened. The yellow LED flashes and the only way I can open the CD tray is to stick an unfolded paperclip into the release hole :-) Is this something to worry about or just due to the drive not being hooked up to the VAXstation? TIA Al.

VT-320 Hack+Tip for Smokers

My manuals all say 'North American' version of something similar. I suspect a common case, and maybe a different circuit board for those folks on the other side of the pond. Any confirmation?

With the LK201, blowing out the dirt is about the extent of it. The keyboard assembly is such that you can not easily disassemble it to do a good cleaning. I had a couple that were really flaky, so I decided to try an experiment. I soaked each of them in a solution for a few days, hoping to dislodge some of the deep down crud. No success. I salvaged the keycaps and disposed of the rest. > I can find better PC keyboards new for around $4.99. If you mean as in 'Wintel', they are not compatable. > What to do. 1) I got a stack of untested LK201's. Stop by (Indiana) and pick a couple up. 2) Try an LK401 instead. Being newer than an LK201, I have only ran across one flaky one. The nice thing about the LK401 is that you can tear down, clean, and reassemble one in a reasonable amount of time. > Well, I cut off > about 3/16" of a cigarette filter (with the paper on) > and put it in the tube above the torn dome connector. > I trimmed it a bit after testing the feel of the key, > and it works rather well, especially for my typing > style (not particularly speedy and somewhat ham-fisted). An imaginative fix! Ok folks, let's empty our ashtrays and ship our butts off to Steve. ;^) Mike
