11/34a problems continue

by fireflyst＠earthlink.net

Well, I've been messing with the 11/34 on and off now for a few months as I feel like it. The problem right now is that I have no light on the H745 power regulator. Both lights are on, on the two H7441s in the other slots. If I need to measure draw on the backplane to solve the problem, where do I do it from? If on the power distribution board or backplane, then at what points? Secondly, do certain modules need to be installed to utilize the H745's resources? (i.e. a device that uses -15vdc) or should the light come on anyway from just being connected to the power distribution board? I've tried with both those modules in and removed from the system, and it didn't seem to make a difference. What do I need to do to diagnose this problem? It's really driving me nuts. Appreciating any help you can give, Julian

dec plastic panel mounts - ordering?

by jwest＠classiccmp.org

I was showing someone my collection, and while standing in front of my 11/45 restoration project I lamented about how those little black plastic brackets that attach to the upright rails just can't be found anymore. You know the ones... the bracket has two round knobs that always break off - these are used to mount DEC filler panels. He said he knew a plastics firm that may be able to do a short run at a reasonable price. Failing that, he felt another company he knows of may be able to make them out of metal. This gives rise to two questions... 1) Would replicas made of metal work as well as replicas made of plastic? 2) How many people would be interested in some if the price is reasonable? And how many? I know a few of my systems I'd go back and use 4 brackets on each panel instead of the 2 I skimped on. In addition, a few racks I simply couldn't mount filler panels at all because of no brackets. Of course, before the guy can quote me a price I need to give him a firm minimum count. The more in the firm count the lower the price is. I figured I'd order 40 or 50 if the price was reasonable. But I'm sure my own order would be cost prohibative unless other collectors jump in. On the other hand, if some collector has a big crate of these, I'd rather just buy pile of originals :) Jay West

URGENT: Data recovery assistance needed in New Haven, CT

by mamcfadden＠cmh.edu

I actually think I saw a system like this at the local computer surplus place about a year ago. It had a display like a Microfiche viewer with a MO disk drive and a hard copy output connection to a laser printer. Somewhere I have one of the disks. *****PREPARE FOR LONGWINDED COMMENTS***** I'll bet the data is not in a standard format. The hospital where I work has lots of MO disk using systems, CT scanners, data backups for patient monitoring, Cardiology cath lab and they all use non standard data formats. The CT and cath lab are the worst they use a raw file structure that is directly read and written by the system. They also encode the data in a compressed format to pack more data on the disk. The MO disk media manufacturers are also not producing the media any more. I have several of the drives but we have never been able to read one of the disks without the drive it was originally created on. The venders consider the storage format proprietary and will not release it. Back 10-12 years in the past we reverse engineered the data structure that was on an LMSI 12" optical drive containing digital x-ray images. There was a hierarchy on the disk and the data was stored in a run length encoded format of the differences between different resolutions of the images. We made disks up with 1 image and then compared it to a blank disk, then added an additional image and repeated the process. We were eventually able to read the disks offline and purchased LMSI drive to connect to our VAX. We have this exact problem today, a SCSI MO disk from a GE CT scanner and no system to read it. We kept the drive but there is no software. GE will sell you a system with software to read the disk for $20,000 or transfer an individual disk for a fee. Mike

Thanks guys :-)

by legalize＠xmission.com

I don't know if it was due to cctalk'ers or not, but ebay just gave me $100 gift certificate for the serial terminals guides that I wrote. If you voted my guide(s) as useful, thanks! -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

RSTS on a VAXserver 4000?

by legalize＠xmission.com

Can you run RSTS on a VAXserver 4000? It just occurred to me that this might be possible. From my personal usage I had only thought of RSTS in a PDP-11 context. If it can run, am I limited to using a particular version (presumably because it would need VAX support?). PS: Recent addition to LibraryThing: VAX Systems & Options Catalog 1988. I will be scanning/uploading the pages on the VAXstation 8000 to my web area soon as this is a machine with E&S 3D graphics hardware. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>
