don't hook no RA90 to the internal power plug on the VAX6000

by gunther＠aurora.regenstrief.org

Hi, I think I haven't heard from Geoff of Oz for a while, are you still around? Came to think about Geoff because I have now blown two fuses of VAX 6000's internal 110V power hookups (the main power box has three what looks like standard 110V receptacles.) But not all of them are equal, so it seems. The one that's not reachable from the outside seems to be protected by a low-rated fuse. I suppose now that this is where the backup battery is to be hooked up an nothing else. I tried to drive an RA92 from there and it always burned the fuse when the drive spins up. I'm releaved now because initially I thought I might have destroyed the drive (some inner short because of dust and dirt.) But it's just that fuse. Too bad that I can't power the second external receptacle. It's this weird 3-phase conversion issue where you have to use the phase that connects to this internal receptacle but not both of those that connect to the two external receptacles. How did you, Geoff, hook up both of your RA9x down in your VAX6400? thanks, -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

RA90 not releasing session on port B? How can I reset the drive?

by gunther＠aurora.regenstrief.org

Hi, I cleaned up my laundry/computerroom real nice. The two VAX6450s now want to talk to each other (and not just stand side-by-side :-). I have the star coupler attached to the wall, at a nice angle under the staircase, which makes it really nice to connect the CI cables. Can't wait to do IP over CI between the two. So, I copied my Ultrix disk's / and /usr partition to another drive and having connected the second VAX6k to that other drive on SDI port "B" I could actually boot it with the generic kernel and so forth. Then I found I was missing something, so I wanted to get back to the first VAX and mount that drive again to add something to it. But fron then on every attempt to mount or write to the drive from port "A" causes the WRITE PROTECT LED to lite up quickly and then the OS comes back with an I/O error on writes and a write restricted error on mounts. I can't even do mount -r that drive. I tried shutting down, spinning down, resetting, powering off and everything I just can't get the drive responding to write requests from port A any more. What is the magic here? These drives seem to have a memory that lasts even when powered off. Once I turned off the main breaker before the drives were spun down. It does sound ugly, but they all work nicely still. And I noticed that they remembered the "R" status when I powered them on again. So, how can that memory really be cleared? thanks for your help, -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

Performa 476 Problem

by appleone＠mac.com

Brian: How about the motherboard backup battery? I've seen a couple of Macs that wouldn't display that worked fine after I replaced the battery. Check the voltage on 'em. Of course, another known working monitor would be nice for testing too. And even with no hard drive you would at least get the "flashing question mark disk" icon. Steve

Diagnosing a non-working Mac Performa 476?

by Innfogra＠aol.com

Not being an Apple person this might not be germane. I have found differences with the cables that attach the monitor to the computer. I had one cable that plugged in but did not work. It was lighter in weight and IIRC was missing a pin. I think it worked on an IIGS but not on a LCIII I was testing. I needed the heavierweight video cable with no missing pins to get the LCIII to come up. Both came up in color but needed different cables. Don't know why. As I said I am not an Apple person, although I would love a G3 or G4 to play with. Paxton Astoria, OR

the haunted VAX6000 has been exorcized!

by gunther＠aurora.regenstrief.org

Yes! It was very much like Antonio suggested, a good deal of previously strangely behaving XBIA and XBIB boards were still working fine given the proper environment. I replaced the backplanes/cages for both XMI and VAXBI. I figured if nothing else, the set I put so neatly into boxes last year would be less exposed to dust and grime over the last year, and I did remember that one of the vaxen, i.e., this particular one did behave strangely even last year. Then step by step debugging with a little bit of board reseating and everything works now. Yeah! This is my second VAX6450 going online. Did I mention that one of them is now a VAXvector 6450 (with one vector processor right now because I still don't have more than one of the little cables.) It's going to be a VAXvector 6440 V2 (BTW: how was the number of vector CPUs officially counted?) and the other will be a VAX 6460. Both of them have 512 MB memory, one has a KDM70 with an SA600 with 8 RA90s the other now has the KDB50 with one RA90 and one RA92 in the "basement" of it's cabinet. I'm about to connecting the second VAX to the star coupler. And then all I need to do is fix the HSC90 that still gives me a k.ci error with status 111 (what the heck does that mean?) Then the HSC90 will plug in the port "B" of all the RA90s and RA92 and uh yes, there are also the RA81 and RA82, which I can't wait to actually use. My basement is going to be cleaned out now. It looks nice with two VAX 6000 and an SA600 shoulder to shoulder. Ah, yes, now I have an XMI and a VAXBI backplane cage spare. I will get rid of it one way or the other. If you want either or both, let me know. They are free for the taking or shipping. I'm sure that only one of them is actually defect AND I'm sure the defect could be fixed (I'd probably go with round in the dishwasher or so.) If you need parts from one, that's fine too. To know what's on them go to my VAX 6000 anatomy page. If I don't hear by soon, I will screw off all the parts and let the bulky stuff hit the dumpster. regards -Gunther Here is the transcript of a working VAX 6450 selftesting: >>> INIT c123456789 0123456789 0123456789 01234567# F E D C B A 9 8 7 6 5 4 3 2 1 0 NODE # A A . .

There are many things one can do with a non-functioning Next Cube.

[CCTECH] Cards to Identify

by Innfogra＠aol.com

Finally read the description on the large cards. With 3 50 pin connectors I think it is a Bridge of some sort. The 82586 is intel's intelligent Ethernet controller so I am sure the 15 pin is an AIU Ethernet connector. Paxton Astoria, OR

It gets it's speed from having a better memory model. You don't have to program in BASIC with it. In fact, the BASIC is written in Forth that underlies the BASIC. From what I'm told, you can access the Forth. If Forth isn't your cup of tea, most all Forths have been able to access the raw assembly level without using yet another tool. The processor is based on the 8051 instruction set but it one or two clocks per instruction instead of 12 to one. Of course, it runs in the tens of megahertz. Mixed assembly and Forth often makes a good optimization of speed and memeory size. Later Dwight
