Please need your help 2003 actual answer for Power Sentry HUB

by pietrovigno＠hotmail.com

Hi Vintage Your quote : Ok, next question, I need the power supply specs for the Power Sentry USB hub. I opened it up to try to determine what it wants but am not savvy enough I guess. It has a 278R05 voltage regulator on it (listed here: http://www.lekwong.com/product_infor.htm#ic04 but no specs) but I have no data for it. What was your finding at the time for actual voltage of Power Sentry Hub a long long time ago? I have currenlty exact same question. I would appreciate answer. Thank you very much uin advance

DEC M8043 (DLVJ1-M) Configuration help?

by tiggerlasv＠aim.com

You can find alot of documentation on the bitsavers website, though some of what you need is hidden away inside other documents. The configuration settings you need can be found here - http://www.bitsavers.org/pdf/dec/qbus/EK-192AA-MG-001_Microsystems_Options_… It's been years since I've messed with a DLV11-J, but if you have any issues, let me know, and I'll see if I can walk you through it.

amusing letter found in a C64 box

by starbase89＠gmail.com

Hello I recently picked up a boxed C64 off the curb and found a letter inside from the owner of the machine to a repair center requesting service. I found it somewhat amusing and thought others might as well. http://img842.imageshack.us/i/img035c.jpg/ -Joe

Where does one find small 4:3 LCD screens with composite or S-video input?

Non-widescreen name-brand (**) computer monitors (at my day job we had literally acres of 1280x1024 screens) and TV's pretty much (*) disappeared 2 or 3 years ago. (*) The exceptions I know of, are probably new old stock, and I do see them showing up in security systems and point-of-sale terminals. (**) I know Viewsonic stopped making them a couple years back because the Viewsonic reps warned us of that like 4 years ago. But if I go to Amazon I see a companies called "V7" and "Planar" selling what I think may be new 17" 1280x1024 LCD monitors. Tim.

Where does one find small 4:3 LCD screens with composite or S-video input?

by ethan.dicks＠gmail.com

Hi, All, It's trivial right now to find inexpensive 16:9 LCD TVs in various sizes, and I'm seeing a lot of older, smaller 4:3 VGA LCD screens in thrift stores and what not, but what I'm not finding abundantly are (presumably used) 4:3 LCD screens with 15KHz-friendly inputs (composite, S-video...) I've found a few places (Amazon, uBid...) with old pages now marked "out of stock" for items I'm interested in, but as of yet, I have not found anyo able to take an order. One example part number for a product that I think might fit what I'm looking for is the Sharp LC-12A2U (12" 4:3 LCD TV). It's trivial to buy a remote for it, it's easy to find a manual for it, but nobody sells the TV itself, either as a clearance item or used. Is this a side-effect of the analog->digital TV conversion? Did everyone, all over, crush all their non-widescreen TVs, never to be found again? My interest is in repurposing these devices into traveling displays, with or without an enclosing kiosk, and since I'm planning on generating the content from older (on-topic) devices, I'd prefer 4:3 to 16:9 since that's the display "look" that 1980s micros were designed around. I have a couple of 12" 4:3 monitors already, but they are VGA-only. I was hoping to find an older device with the right inputs vs buying/finding/building a VGA scan converter since I'd been expecting a used TV to be cheaper than a new scan converter, but so far, I'm coming up empty handed. So has anyone spotted older, smaller LCD TVs anywhere on-line or in physical stores? -ethan

DEC M8043 (DLVJ1-M) Configuration help?

by captainkirk359＠gmail.com

Hello CCTech people, I've recently gotten my hands on a nice little PDP-11/23 system. The main console interface is a DLVJ1-M, that I think may not be in the correct configuration (as I think one of the wire-wrap jumpers may have come off). I can't find any manuals for a DLV11 or DLVJ1, so I'll try to explain the problem. Comparing the DLVJ1 to the DLV11-E maintenance print set on BitSavers (not the same device, but mine appears to be identical to the one in the print set), I've noticed all the jumpers are the same between both except for one block. There's a block of jumpers that looks like: Z? ?Y 0? ?W 1? ?K 2? ?V 3? ?N Which in the maintenance print set has jumpers 0, 1, 2, 3, and N connected to one another. Whereas on my DLVJ1 only 0, 2, 3, and N are connected. Having no manual that explains anything, I have no idea what the current configuration of mine is. So, my question to all of you here on CCTech is: What is the current configuration of my DLVJ1? And more pressing as a question: Does any one have a manual that explains what all the jumper settings are? I ask all of this because, I believe the jumper that connects to pin one of that block, may have come loose and fallen off, which - I'm thinking - would result in the system reaching an advanced state of non-functionality. (Then again, all it does right now, is console ODT; as I've no mass storage, but I do have an RQDX3 and 9058 distributor.) Thanks in advance for any help. -- C. M. Gauger-Cosgrove

Info on QED 993 (QBus PDP-11 processor)

by derschjo＠mail.msu.edu

Anyone have any documentation on a QED 993 processor? From what I've been able to find on the 'net (which is not much) it's a 3rd-party, Qbus-based, quad-width PDP-11 upgrade, which has 4MB of RAM onboard and is supposedly faster than 11/93. I just took a gamble on one (the seller icsscorp on eBay -- the same seller who had the CMD SCSI boards a week or so back -- has been auctioning a bunch of these off one by one) and I'm hoping to put it in my 11/73. It'd be nice to have some official documentation. Thanks! Josh

ebay: it can be yours for *only* $200,000

by legalize＠xmission.com

ebay item # 190523729625 This seller routinely lists vintage items at very high prices. (SWTPC 6809 for $2,989.99; Apple IIe $99.99; IBM external 3.5" floppy $99.99 as examples.) Now apparently he's getting out of the business. I doubt anyone is going to pay $200K for his inventory. I seriously doubt his claim that his inventory has a value of $700K. He does have quite a number of interesting systems still in stock. I believe this is because he asks too much money for them. I also suspect that he buys things from other ebay sellers and then marks them up, which is why his prices are higher than the average ebay market price for the same item. I have literally seen an item sell on ebay and then the exact same item listed on his store within a few days for a significant markup. Since he is "retiring", someone in NY might be able to show up and get a bargain. Because I am not close and had a bad experience with him before, I won't be approaching him, but maybe you'll have better luck. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
