VLB SCSI?

by mhstein＠usa.net

Well, I'm not sure that the S-100 "standard" was all that rigidly adhered to either, not to mention that everything else was proprietary at that time (not to mention IBM's infamous Slot 8, PS/1's and MCA, non-standard memory modules, etc.)... New PSU fans are still abundantly available up here in Toronto; if ya really need one, or a complete PSU (especially an odd-sized one) or anything else for an old PC, drop me a line. mike -----------------Original Message--------------- Date: Sat, 27 Oct 2001 17:19:50 -0600 From: "Richard Erlacher" <edick(a)idcomm.com> Subject: Re: VLB SCSI? <snip> because IBM no longer provided a firm ISA-equipped standard that everyone else could clone, there was nothing but chaos, and that's the way it's been ever since. The whole concept of "standard" was corrupted in the course of this evolutionary step, and it was a step into the quagmire we're all swimming in today. <snip> <snip> BTW, if that "bulky old PSU" still works, I'd happily relieve you of the fan and PSU board, and pay you for the freight, except for where you're located.

How to disassemble an HSC90?

by gunther＠aurora.regenstrief.org

Hi, has anyone of you ever disassembled an HSC cabinet? I am looking pretty stupid right now. It's not the first piece of DEC iron equipment that I have moved in pieces, I did two VAX6000 and one TU81+. But this one is different. While being half-height like the TU81, it's quite a bit deeper. The side-walls appear to be just locked at the bottom and then hooked such that one can lift it up and off, like the TU81's side walls. However, they do not move no matter how hard I try. I don't find any screws holding them, though. And with the sidewalls on, I cannot remove the top-cover either. So, I was hoping I could at least take it into two pieces by moving the whole core out in one piece. Apparently that central unit is just screwed on the front, like a rack-mount device. Indeed I can move it out quite far. But then it stops at a protruding piece of the backplane circuit board! There seems to be no way to move that core all the way out other than by removing the backplane circuite board. And I'm not going to do that. Other DEC equipment was quite straight forward to disassemble, but this one beats the auto-assembies in difficulty level. I appreciate every advice. My suspicion is that the sidewalls are indeed removable, but mine are just stuck. Someone seen it? regards -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

first step getting VAX 6000-400 booted ...

Each attempt at rewiring and rebooting costs me >about one hour for the VMS to boot from TK again so I need >to keep this minimal. OK. If standalone backup does not see the drive before you get to the $ prompt then something is clearly wrong (it should report a set of available drives, one of which should be DUAn: where n is the unit number). Check the drive first. Press the TEST switch - the TEST light should come on. Press the FAULT switch and *all* lights should come on. Now you know the lights work - press the TEST switch to leave test mode. You can run a set of drive tests as follows: - Power up: you'll setle with a display of R AB - Deselect A & B - press TEST - press Write Protect Now the display is T 00 with the rightmost 0 flashing - Use A & B to select a test number - Start the test by pressing Write Protect The display changes to S NN Once the test has finished the display changes to C NN - Stop the test by pressing A or B - Press TEST to leave test mode. One suggested set of diags is: - Spin *down* the drive - Select T 60 - Press Write Protect to start the test - The display does something like: S 60 LOT C 60 T 00 - T 60 has not done anything - it will simply loop the next test. - Select T 00 - Press Write Protect This will run a set of diags repeatedly. Leave to simmer for 5 minutes. Repeat the above with the drive spun up. (It performs a different set of diags). If all that uncovers no fault, there is a good chance that your drive is OK. You have tried a KDB50 and a KDM70 - assuming those are installed according to the manual, and the processor can see them, then that leaves just the cabling. If you have a KDM70, I would try to use that rather than the KDB50 since that way you do not depend on a working VAXBI bus. >Do we know the pinouts and signal patterns of the SDI (and >BTW the KLESI) so that I oculd use my scope to detect if >the wiring is O.K.? I didn't find pinouts and signals in >the KDB50, RA9x user manual (or the KLESI user manual >respectively). I've never come across a broken SDI cable, but it may be worthwhile doing a simple continuity check - each should be eight cables (four differential signals IIRC). Antonio

Do we have a VAX organization?

by Innfogra＠aol.com

One of the big problems that I see is Storage. Paul Pierce had to buy a building to store his collection of big iron, it will become the museum in the future. Big Iron takes space, dry space, with a concrete floor and a loading dock to handle comfortably. Does anyone have extra space. I know of good cheap space in Portland, OR but, as we know rented space is very expensive in the long run. I think it is a good idea to plan ahead for machine deinstalls. They often do come out of service in large batches. Not only are they much less common later but parts and manuals often become very scarce. How about a concrete slab/steel building in the dry part of the South West. Anyone have property or a building for long term storage. I am willing to help with my shipping skills anywhere in the Northwest. Paxton Astoria, OR

VLB SCSI

by mbbrutman＠magnaspeed.net

I've never had a problem with two Adaptec 2940AU cards, an Adaptec 1542, or 2 Adaptec 1520s. The drivers leave something to be desired once in a while. My 486 VLB system runs a Buslogic BT445S SCSI card (Fast SCSI II) and an ATI Graphics Ultra Pro. The Buslogic has been a wonderful card; it's been in service 7 years now under OS/2, DOS, Winblows, and now Linux. Too bad they were bought out by Mylex, and eventually disappeared into oblivion. Any other Buslogic owners out there? The ATI card was marvellous at the time - 1280x1024 in 256 colors with a 70+ Hz refresh rate. It's a little flakey now - the system requires me to hit the reset switch before it will boot. Replacement ATI VLB cards have been DOA ... apparently they don't age too well.

Having just dropped a rackmount Cromemco System 3 in the process of moving it, I can assure you that it's (relatively) big and there's lots of iron in that PS transformer... and IIRC, it can support around 32 terminals or so running UNIX with the right cards. --------------Original Message-------------- Craig Landrum skrev: >Also, having just joined this list, it would appear to be >dominated by primarily big iron types instead of us IMSAI >and S100 junkies.

Peter Wallace wrote: >Something I remember on RA81s is that you have to go from >controller --> cable --> bulkhead connector --> cable --> disk > >if you go directly from controller to disk, you end up with pins swapped >and things dont work (but nothing hurt) I think the rule is you have an *odd* number of connecting cables - since each cable swaps. So in a MicroVAX 3600 you can go directly from KDA50 controller to RA7x internal drive. Or you can go from KDA50 to bulkhead, bulkhead to bulkhead on next cab (e.g. storage array) and from there a third cable goes internally from bulkhead to final drive. In the case of a 6000 typically you go from KDB50 (or KDM70) to bulkhead on 6000 chassis. Then 6000 chassis to Storage Array chassis. Then internally there is a cable from the Storage Array bulkhead to the drive itself. I don't know how the wiring was done for those later kits that allowed RA9x and/or RA7x drives to live in the bottom of the VAX 6000 chassis. Antonio

Tadpole Sparcbook 2: need bootable software

Greetings all, I wonder if anyone can help me out here. I have a Sparcbook 2 I am trying to resurrect. One of the disks crashed several years ago. I have finally got around to finding a replacement, but now my backup tapes are unreadable, and the CD-ROM I have (NCE 2.0 for Solaris 1.1.1 Version A.2.3) turns out not to be a bootable OS installation CD at all :-( So, I am in search of a CD-ROM of the appropriate kind, or downloadable images of the relevant "stuff" so that I can boot this sucker across a network. I would appreciate a direct reply to my e-mail address so I don't overlook such a reply in the mass of stuff on this mailing list :-) Thanks, Bob. -- Bob Bramwell Snail: 60 Baker Cr.

Even though the scaling row is usually left unused in robot apps (but it still is used for computations in the IIT FPU), thus producing some inefficiency, the built-in 4x4 was still much faster than a 3x4 matrix multiply algorithm. carlos. -------------------------------------------------------------- Carlos E.
