Almost on topic - Cassette I/O

As to the cassette drive, I wasn't entirely serious in suggesting it; it's a very non-standard Burroughs interface and I think it would be more work interfacing that than your whole computer project including the cassette interface. But if you're looking for a *real* challenge.. The PPT stuff also uses proprietary parallel interfaces, Burroughs and SCM (CDC?), but that would probably be a lot easier to do. Looks like the AC-30 may be spoken for. Did you get enough info on interfacing the cassette, or want me to scan something for ya?

Apple II SCSI card

by paul＠orchard.wccnet.org

Rich Beaudry: You have an Apple II Rev C SCSI card, not the High Speed card. Below is a comp.sys.apple2 post with more details about the card, including some limitations. I have one in my IIgs. I also have the original manual and software, but the Chinook SCSI Utilities (CSU) software is better (see below). I can provide you with copies of this stuff. I can point you to online sources of disk images if you can handle them. For others with Rev A or Rev B versions, I can make Rev C EPROMs. Paul R. Santa-Maria Monroe, Michigan USA From: David Empson (dempson(a)actrix.gen.nz) Subject: Re: Apple II SCSI Card rev C - Latest Revision? Newsgroups: comp.sys.apple2 Date: 1998/09/11 Brian <brwiser(a)xmission.com> wrote: > I just acquired an 1996 Apple II SCSI Card revision C, for my ROM 1 > IIgs.

The ROM should be labelled "341-0437-A" if it is revision C. Revision C is the last release of the firwmare for this card. > Are there any problems I should be aware of? Many. Where should I start? 1. The card is not terminated. If you are connecting more than one device, you must place a pass-through terminator between the card and the first device (or internal termination in the first device), as well as after the last device on the chain. If you are connecting a single device, it should have internal termination or a piggy-back terminator. 2. The card does not supply termination power. There is a single diode modification that can rectify this. Another option (my preference) is to make sure that at least one of the connected devices is able to supply termination power. 3. The firmware is limited to seven logical partitions. These partitions may be spread over as many as 7 SCSI devices connected to the card. Under ProDOS-8, this gives a practical limit of 224 MB accessible over all volumes. Note that you need to be running ProDOS-8 2.0.1 or later to be able to access more than 4 partitions, and this requires at least an enhanced IIe. Under earlier ProDOS versions, you can only access 3 or 4 partitions if the card is in slot 5. The seven partition limit does not apply under GS/OS, which uses its own drivers. 4. The firmware doesn't fully support removable hard drives, including devices like ZIP drives. The problem is that if you switch disks, the firwmare does not update its saved copy of the partition table. This can easily result in corruption of the new disk if it is not partitioned EXACTLY the same as the previous one (right down to the starting block number and number of blocks in each partition). This problem doesn't affect GS/OS, and you can work around it under ProDOS-8 by rebooting if you need to change disks. Note that if you boot via GS/OS and then get into ProDOS-8, quitting to GS/OS and relaunching ProDOS-8 might not be sufficient to reinitialize the firmware (I haven't investigated this). 5. The firwmare only supports SCSI hard disks and CD-ROM drives. CD Audio operations are only supported with Apple's original CDSC, CDSC+ and CD-150. This isn't likely to be a major issue. 6. The card is slow. The Apple High-Speed (DMA) SCSI card is a lot faster (as long as DMA can be used), and the RamFast is even better. 7. The partitioning software that comes with it is pretty limited. If you didn't get the disk, this isn't an issue. A much nicer 8-bit alternative is Chinook SCSI Utilities, which is now freeware. (I don't know of a source for it off-hand.) You can also use Advanced Disk Utility under GS/OS. -- David Empson dempson(a)actrix.gen.nz Snail mail: P.O. Box 27-103, Wellington, New Zealand

Do we have a VAX organization?

by gunther＠aurora.regenstrief.org

Hi, I usually hate organizational issues, but I think us VAX collectors need at least a semi-formal organizaton. Why? - Most importantly this could help convince those that either decomission or scrap VAX hardware to give it away instead. (Yes, the last wave of decommissioned VAX 6000-600 and 7000/10000 is coming up, plus the tail of older models that might occasionally still be in use.) Also think of all the overpriced DEC hardware suppliers who soon have to get rid of their stocks that no business customer needs anymore. - Second this would give one point where we could organize trades and consolidate shipment issues ("VAX trecks") - It could help us negotiate good truck rental rates. Penske has perhaps the best rate you can get, but not everyone gets the best rate (i.e. 10 cents per mile) because that's for business customers only, normally. But usually with an organization (and a little ad on the web-site) you can get good deals on vehicle rentals. And it goes on. - We could promote semi-public collections like little private museums that some of us are building. - Finally it could help in right out fundraising for covering such expenses as electricity and internet connectivity for cyber- museums and public use VAXen. We don't have to start all over but can take something that already exists. (I'm also not looking to become a chairman of anything, one of the typical incentives for people suggesting new organizations :-) For example, I think this can start with a web site. Some of us already have vax related domain names which we can use, like Isildur's vaxpower.org. So, a www.vaxpower.org could be it. There's also the VAX rescue squad, put in my several futile attempts to sign up I realized that this project seems rather dead. I don't know if this should be anything tightly connected with DECUS, because DECUS is (a) too COMPAQ or whatever.com oriented, (b) too VMS oriented, and (c) seems to have too much overhead (organizational structure, membership fees, unrelated agenda items). But I could be wrong about that. Another question is if this should not be a DEC/VAX only group but rather a vintage computer stuff group, like Sellam Ismail's site. May be this could be it. What's important is that this site would help accomplish above-mentioned goals, and that it would be a showcase of our VAX collections and simply an address book of the kind that the VAX rescue squad wanted to be. Something you can point to when negotiating with a source. A network of friends you can call up and ask for help in rescuing someting in an otherwise remote area. Also a set of rules of conduct dealing with shared hauls, (like what if: you agree to help with a haul from a friend accross the country and agree on keeping certain things, but suddenly a PDP-8 shows up in that lot? These are things that could help maintain friendship and integrity and reduce grief.) So, what do you think? 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

Are you talking about a MS Windows box here??? As a PC builder I must say that if I were into serious gaming I would absolutely buy a game console. Say you buy 3 pricey, high-quality games for your PC. Chances are one of them won't like your video card. Or the version of DirectX you're running. Or the gamepad you're using. Or the motherboard's chipset. Or it'll step on another game by replacing DLLs. Or it'll change the sound settings so the other games have problems. Not my idea of *fun*. On the other hand I suppose you could consider the "real" game to be getting more than 3 high-quality games to run on the same Wintel box ;>) Glen 0/0

first step getting VAX 6000-400 booted ...

by gunther＠aurora.regenstrief.org

Hi, after my pretty good VAX treck last weekend (more details coming up on my project web site at a later time) I finally have SDI disks. I hooked one up last night and did all the checking as per the RA9x manual (yes I have one plus many more, will scan those at some time...) and it seems to be O.K. (even though it was pretty messed up stored in a barn among lots of birds for many years). Here is one para about where I am at and then I have some specific questions for Geoff Roberts or Ragge or anyone who has had experienced any luck with getting a 6000 up to operation. I have bootable tape for Ultrix 4.1 and VMS 5.3 both TK50. None of them work. I seem to have no luck with the TK70 and I have no way finding out what's wrong. I tried to boot from that RA90 disk, even though I don't know what's on it. It has unit #0, so I thought it might be a system disk. But that too failed with some I/O error very early in the process. I also have a TU81+ and VMS bootable tape on 9-track, maybe that's more reliable? Tonight's project is to move the TU81+ into the basement and hook it up. I'm afraid I'll get stuck there too and what then? Network booting? Here's some more detail and questions: The TK50 boot proceeds for quite a while, although it never shows any message on the console about where it is at before it halts due to some unspecified error. However, about one or two minutes into the tape running the system-panel's FAULT light comes on and at the same time both yellow and green LEDs on the TKB70 board extinguish. That's for about a second or two. Then the lights go back to normal and the fault light turned off. Another 30 seconds to a minute tape streaming and the same light-spiel happens again: fault on, TKB70 LEDs off, and back to normal. Now a shorter time (like 10 seconds) of tape streaming and again. From now on that repeats for about 4 or 5 more cycles and finally the system is halted and console says: system halted due to previous error. However, no error message is being printed. I have no idea where I am in the process. I have tried cleaning the TK70 read/write head of course. I have tried a different copy of that Ultrix tape. It's always the same. Is this bliking of fault and shutting off of both TBK70 LEDs normal for media read errors or does it indicate something more serious? How can I tell where in the process I am? Is there an error flag somewhere in memory that I could EXAMINE to find out what is wrong? BTW: at first I had my CIBCA cards in and the boot process would halt earlier: system would say "insufficient memory for CI" and "10% or more of the memory is bad". Who is checking memory there? I could not find anything in Ultrix 4.2 sources that would generate such a message. And why would it anyway, because my system check tells me that I have 512 MB of memory OK. Or does it speak of 10% of the CIBCA's internal memory? Is there a boot flag that I could turn on that would cause the loader etc. to be more verbose? Has anyone tried booting Ultrix over the network? I am going to try that but all I have is Ultrix on TK50 (that doesn't work) and sources without any VAX running to compile them on. Is there a cross compiler suite? I'd like to compile with the DEBUG flag set.

Power off. 2. Turn the nylon catches on the card cage cover 1/4 turn each and pull cover up and out. 3. Swap modules to taste. For removing the rear door: 1. Open door. 2. Release hinge pin by pulling down on release lever. 3. Slide door out and lift up: do not bend bottom pin. I've never (knowingly) seen an HSC6x or HSC9x so all I can say is that it sounds pretty easy so I assume you are doing something other than swapping modules? The IPB suggests that the side panels "hang" on the sides and, once the top is off, will slide upwards until they are clear of their "hooks". There may be some obvious screws involved too (it's not immediately clear whether this is a different cab variant/rev or not). Antonio

TU81+ spooks (was: Re: first step getting VAX 6000-400 booted ...)

> Gunther Schadow wrote: >I did try MUB0 (because that's how VMS calls it for me), but >that doesn't work. I just like VMS calls my disk DUA0 but to >boot from it I have to call it just DU0. So MU0 it should be. >The CSA1 is weird, because it's really MUC6 for VMS, and it >should be another MU. The console's idea of a device name and VMS's idea of a device name will not always agree. For MSCP SDI disks (like your RA90) the device name will usually be DUAn:, where n: is the unit number you have given it. OpenVMS will sort out how to get from that unit number to a specific path to the device (possibly hanging off a CI rather than on your local machine!) The console usually does not bother with such shenanigans. It wants you to tell it how to find the device. For example, on a VAX 82x0/83x0 box you would boot as: B DUsn: where s is something like the VAXBI slot number in hex, and n is the unit number (also in hex IIRC). Of course if you put your KDB50 in slot ten then you can do: B DUAn: but that just hides the difference :-) Once VMS boots you can do: $ MC SYSGEN A A /L (that's AUTOCONFIGURE ALL /LOG) and it will go off and find most things. Then SHOW DEVICE D will list the disks (really any device that starts with D) and SHOW DEV M will show the Magtapes. The Console Storage device (CS) is generally not visible without being explicitly made so via SYSGEN, so it will generally not show up. >Yes, that would be the crucial question?

If someone could test >copying a bootable TK to TU and then try TU booting? I don't know whether the VAX 6000 can cope with booting from TU81+, nor do I know what, if any, controller support it expects for a device to be bootable. (I don't know how much of a boot driver is implemented in the console and how much needs to be provided by the controller). If you do want to backup your system disk, the steps are as follows: 1. Install standalone backup on the system disk. $ @SYS$UPDATE:STABACKIT SYS$SYSDEVICE: This *should* (if I've remembered it correctly) create a standalone backup in root SYSE (i.e. $ DIR SYS$SYSDEVICE:[SYSE] should now have something in it ... don't mess or delete any of this though, most of it is effectively symlinks to stuff that matters!) 2. Boot as normal but with R5's top byte set to E, typically /R5:E0000000 should do this for you. 3. Standalone Backup should come up in a few minutes rather than a few hours! 4. $ BACKUP/IMAGE/VERIFY/IGNORE=LABEL SYS$SYSDEVICE: mua0:SYSTEM.BCK /SAVE mua0: is whatever the tape device wants to be called (MUB0:, MUB1: CSA1:, whatever). SYSTEM.BCK is just the saveset filename /IGNORE=LABEL means "I don't care how valuable that tape is, I know what I'm doing so wipe it!!" /VERIFY means it will take twice as long but there is a possibility that you may be able to restore the data one day :-) It's been a while, so this probably won't work first time.

Do we have a VAX organization?

by mhstein＠usa.net

Maybe not just for VAXes? >From another perspective: A friend and I were both selling & supporting Cromemcos in the 80's and early 90's and, although neither of us is a "collector," as time went on and they became obsolete, we took them all back & hung on to them, first for parts and then because we didn't have the heart to throw them out. A few years ago we decided it was time to clear out the space and get rid of them, but could not find anyone seriously interested locally or on the 'Net at that time (mind you, being in Canada does make shipping a little expensive), so we hung on to them a little longer. Recently we both needed space again; he decided that it wasn't worth the time and trouble to find a good home for them and tossed most of his into the dumpster, while I thought that surely there'd be lots of people who'd give their eye teeth (and maybe even a couple of bucks) for this stuff. I did get a few inquiries for a card or two, and several people wished that I were in California or Minnesota (or that they were in Toronto, although, at least for the Californians, that's less attractive as winter approaches :). And yes, I was contacted by a couple of local collectors who will probably take a few of the systems. But on the whole, so far it has indeed not been worth the time and trouble, especially since (unlike HP & DEC) there's not much of a user community (knowledge base) out there and people prefer them to be assembled & working instead of a pile of chassis and boxes of manuals & untested cards. All this to say that it sure would have been nice if there'd been a central place with the organization & resources to arrange and/or pay for shipping the whole lot and a few bucks on top, and then dole them out to interested individuals. As it is, unless someone local actually wants it all, most of it will have to be scrapped. Thanks for the tip about the value of scrap, BTW; believe these boards & connectors were still goldplated... mike

Apple II SCSI Card Questions

by r_beaudry＠hotmail.com

Hello all, I just today received an Apple II SCSI card (NO docs), and I have some questions... First, a description of the card: Typical sized Apple II card, has a ribbon cable with one connector soldered to the card, and the other terminating in a female 25-pin "D" shape connector. There is a 40-pin chip labeled "NCR/5380" on one line, followed by "C476217", "6-1082073", and "8810S" on separate lines. There is also a 27128 EPROM, labeled "341-0437-A, (c) Apple '87". Aside from some glue logic, there are also two PALs, an 8-position jumper block, and a 6264 SRAM chip. The card is silk-screened "607-0291-B (c) 1986 Apple II SCSI Card", and carries the FCC ID "BC66DSA2B2087". Questions: 1) Is this the High-Speed SCSI card I hear about every so often? 2) Will this card work in a IIgs? 3) Are there any limitations to what SCSI devices I can attach? Ideally, I'd like to add an external hard drive and CD-ROM (Or maybe a Zip drive). Could I do this from this card? 4) Does anyone have docs they could copy and send to me? I'd gladly pay postage. 5) Are there updates to the EPROMs available somewhere? Not that I suspect problems, but if Apple released updates, I'd like to make sure I have the latest code... 6) Does anyone have drivers (if needed) that they could copy and send to me? Again, I'll pay postage. Thanks! Rich B. P.S. I get the digest, so if you could CC: me privately in your replies, I'd appreciate it. I'm a bit anxious to know what I've got here...

How to disassemble an HSC90?

VAX6460: VMS 5.4 how to move on?

by gunther＠aurora.regenstrief.org

Hi, O.K. I am delighted! I did boot VMS 5.4 from that RA90 labeled as unit 0. I changed the system password and am now copying ULTRIX filed off the TK50 tape onto disk in order to write them on 9-track trying to boot from there. Of course I will have all sorts of grief because of the weird VMS blocked file formats. For instance, what I read from the tape should look like this on UNIX: -rw-r--r-- 1 operator 17408 May 12 03:44 file0 -rw-r--r-- 1 operator 2091208 May 12 03:45 file1 -rw-r--r-- 1 operator 6594560 May 12 03:47 file2 -rw-r--r-- 1 operator 727040 May 12 03:47 file3 -rw-r--r-- 1 operator 8826880 May 12 03:48 file4 -rw-r--r-- 1 operator 3143680 May 12 03:48 file5 -rw-r--r-- 1 operator 2007040 May 12 03:48 file6 -rw-r--r-- 1 operator 522240 May 12 03:48 file7 -rw-r--r-- 1 operator 665600 May 12 03:48 file8 -rw-r--r-- 1 operator 286720 May 12 03:48 file9 -rw-r--r-- 1 operator 2949120 May 12 03:45 file10 -rw-r--r-- 1 operator 2160640 May 12 03:45 file11 -rw-r--r-- 1 operator 1249280 May 12 03:45 file12 -rw-r--r-- 1 operator 1024000 May 12 03:45 file13 -rw-r--r-- 1 operator 1495040 May 12 03:45 file14 ... -rw-r--r-- 1 operator 276480 May 12 03:47 file38 and what I have copied from TK50 so far looks like this: $ dir /size Directory SYS$SYSROOT:[GUNTHER] FILE.000;1 0 FILE.001;1 0 FILE.002;1 12880 FILE.003;1 1420 FILE.004;1 17240 FILE.005;1 6140 FILE.006;1 3920 FILE.007;1 1020 Total of 8 files, 42620 blocks. O.K. seems like we have file sizes reported in 512 byte blocks. But file 1 didn't come up right. May be that was because of this read error that keeps the tape from booting? Anyway, before I go to bed I will have copied the first set of filed to disk and back to a tape. Either a TK70 or a 9-track and will try to boot. It looks like I'm making progress, finally. However, I ask myself what to do with that VMS 5.4 system disk. Should I keep it and get another drive downstairs for my Ultrix attempts? Should I rather keep this running 5.4 VMS or should I make a fresh install of a VMS 6.1 of which I have tapes? I am a curious person, so I could first dig in the disks for interesting stuff, but then, I rather want to get away from VMS and onto Ultrix and finally NetBSD. So how much are old filesystems worth keeping? I don't have enough tape to back it all up, and even if I had, how would I do this? How can I find UCX on this VMS 5.4 filesystem? It appears as absent. Is there something like find(1) on VMS? Did UCX not exist for VMS 5.4? Could I install it from a VMS 6.1 bin tape? Do I have any chance of using my ethernet for anything like file transfer or NFS without having UCX? thanks much for helping me accross the VMS river :-) 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

Classic Gaming OT and OT / Re: OT: Playstation 2 opinion?

by mythtech＠Mac.com

>So how many people collect gaming environments? I can't say I "collect" them, but more I have a collection of them (and more units gravitate to me from time to time). I have things like an Odessey (the original one with the littel card edge cartridges, and the screen overlays), Atari 2600 (one market one, one prerelease prototype), Intellivision, Stunt Cycle, Odessey 500(? the newer one), NES, Playstation (1001 model with mod chip, and a 9000 without), and an assortment of stand-alone non TV interface things (like a Donkey Kong, Tron, Crazy Climber, and a heap of space war or driving things). I HAD a colecovision (prerelease prototype unit) and an ADAM add-on (also prerelease), but a friend "borrowed" it many years ago, and it never came back (along with half my atari 2600 carts, the prick!). I was supposed to get a Turbo-Graphix 16 and a Turbo Express, but both fell thru (the 16, the owner forgot and threw it out, and the Express, I turned down because it was a Japanese prototype so I couldn't play it, hind sight I have kicked myself ever since, it HAD been one of 3 in the US at the time, and one of 10 in existance! ARGHH!!) I have not yet begun to aquire Arcade Machines, as I just don't have the room, but I did go half on a Tron with my sister (she stores it at her house). -chris <http://www.mythtech.net>

VLB SCSI? (really 64-bit PCI & 100Mb ISA)

by ken＠seefried.com

Wrapping up a few things here... > <Re: 100Mb ISA cards> 3Com 3C515. Of course, you don't get full bandwidth out of it, but if you really, really have to get an ISA-only box on a 100Mb network, it does work quite well. And there's a Linux driver :-). FWIW...the HP ISA 100Mb card is probably a 100baseVG card, which requires a special hub. > A typical example is the 64-bit PCI. I've seen several desirable > cards offered for the 64-bit PCI, yet I've not seen even ONE advertised > motherboard that actually supports 64-bit PCI. Hmm...there are a bunch, actually. As far as motherboards (as in, not systems) that you can run out to web sites and buy: - Intel boards based on ServerWorks and i860 have them, and they showed up occasionally on earlier Xeon boards - Sun ATX form factor UltraSPARC boards have them - Later Alpha ATX form factor boards have them - At least one version of the Motorola MTX PowerPC ATX motherboard has them (well...okay...this one is pretty obscure) - Finally...my odd/rare Galileo MIPS-based system has them...:-) > From what I've read, 32-bit PCI boards work in a > 64-bit slot, yet nobody seems to be offering that feature in their > advertisement. I'd guess that's because it's cheaper/easier to > diverge slightly from the published standard in making these products, > hence they don't make claims about compatibility. Umm...not sure what you are trying to say. As far as I know 32-bit & 64-bit interoperability *is* part of the the PCI standard, and works vice versa. In fact, I'm pretty sure per the standard, there is interoperability between 33MHz and 66MHz cards. You really only get locked out with 5v v. 3.3v issues. In other works, a card that claims PCI 2.1 compliance will interoperate. Ken

email/browser for DOS or C64/128?

I know I've seen many things on this in th epast but wasn't paying attention. I have some free time now and want to do some tinkering. Are there browsers and email agents for the Commodore 64/128 series and DOS (2.11 through 6.22). I prefer a free or shareware one to be able to test it to see if it's a POS or not. I want to use the DOS version on a few platforms from an 8086/8088 to a 386. I have a 286 portable NEC that I'd like to try it out on first. Thanks in advance.

ATEX?

>This wouldn't happen to have been the Bergen Record... >Used to work for one of their papers as a reporter back before I got into >PDP11's at DEC. Why yes, yes it is the Bergen Record. Right now my project has been put on hold. My friend asked the IT staff about a manual this morning, and they swore up and down that it doesn't matter, the newer version of ATEX will be going online in January. He doubts it, as it seems EVERYTHING they promise is about a year late before it actually gets in place. But until he can find a better person to talk to, there isn't much more I can do. However, I will keep my ears open, if I understand the Atex systems from their web site, the new system will no longer use the PDP-11 that the current one is based off. So one (or more? Atex implies that there may be multiples chained together) may be available soon. I don't have any pull down there to get them, but maybe I can get my friend to find someone I can talk to that does have some say in their disposal. -chris <http://www.mythtech.net>

VLB SCSI?

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 ...

I recall him saying that he has an RA9x in the bottom of his 6000 but I do not recall him stating that he used an even number of cables to do this. >So, the swapping issue seems more complicated than just >an uneven number of SDI cables!

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
