Any intel UPP-103 personality boards for sale?
I am in the market for a UPP-816 and a UPP-878 personality boards if anyone is thinking of selling theirs. Please message me. Thanks Craig
Re: DECimage questions
Thanks so much for the detailed response! I’m especially glad to know regular 72pin SIMMs should work. If I find a DEC reseller that has DECimage or 10Base-T boards for a reasonable price, I’ll let you know. — Chris

DEC's strategy for using X terminals for image display was based around the X Imaging Extension (XIE). That was an extension to the X protocol that allowed an application to setup a rendering pipeline (decompress, scale, filter, color adjust, etc) and then "transport" the image into the pipeline. If the X server had an accelerator, then the pipeline might get mapped onto the accelerator hardware. It was almost a win on the underpowered VAX's of the day (especially for decompression). So to take advantage of the accelerator, an application had to make XIElib calls (analogous to Xlib). The libraries (and XIE) were part of the VMS and Ultrix products, but I'm not sure there was anything that used them (maybe some example programs). I don't remember if board for the VXT2000 had any other capabilities that might have helped with normal X server operations. -- Gary

You have to manually thread the tape when you load it, but I actually consider that a plus as it is one less thing to go wrong compared to an auto loading tape drive. I currently have a couple of them that I have used with Q-Bus systems. I agree with the recommendation to use an Emulex QT13 interface. That is what I have used in TMSCP mode to install 2.11BSD and RSTS/E 10.1 from tape on an 11/73 system. I also have one or more Dilog DQ130/132/140/142 Pertec interfaces (I forget what the models are, some don't have manuals on Bitsavers). Those aren't quite as friendly to set up and use as the QT13. I'd have to look and see how many QT13 cards I have. Probably more than two for the two M2444AC drives I have. I just built cables myself. I have a 3M Scotchflex 3640 press which makes it easy to press the IDC connectors on to the cable. I bought a full 100-foot roll of 3M 1700/50 or 3365/50 cable for a reasonable price on eBay.

Neither a V5.1 nor a V6.03 worked with my MicroVAX 3100 M95, it's built in SCSI interface and OpenVMS V7.3. Light access worked but as soon as you tried any kind of actual work it threw hoards of mount verification messages and errors piled up and became unusuable. On the other hand, the V5.1 worked terrific on my Compaq AlphaServer DS10 with a Qlogic ISP1020 SCSI card and OpenVMS V8.4 Others have had success with MicroVAXen and V7.3 and earlier so I think it's my system, but I haven't had time to work it out yet. -- John H.

Fujitsi 2444AC 9-track tape drive/PDP-11
Hello friends, I recently acquired a NIB 9-track for use in my (someday to be operational) PDP-11/23+ or PDP-11/73 (I've lost track of the details). I got it on ebay for $150 but the shipping from CA to NY was not insubstantial :). The ebay ad showed a well-used unit but when it arrived it was clearly new in box! Nice when that happens :) Some pix: http://w2hx.com/x/VintageComp/Fujitsu-2444AC/ It is VERY heavy! Took me and my 17 year old (and a lot of sweat and swearing) to get it up to the attic where my burgeoning little vintage computing lab is shaping up. I should mention, I'd like this tape drive to be able to work in either the various DEC OS's available (RT-11/RSX/others?) and also Unix/BSD which I plan (hope) to get up and running. Now for some questions. 1. I've been told the QT13 is a very good card to interface here. I've been looking for a while on ebay without luck. I do see a QT14 on ebay right now at a good price, but I am not familiar with the "S" card business and what that means for use in a PDP-11 backplane. 2. Anyone have a QT13 for sale? Or based on my dec and unix interests, is there a better/recommended card? 3. Anyone have the 50 pin cables/connectors available? If not I feel confident I could make these up. But I thought I'd ask in case someone has a set getting in their way 4. Anyone ever make a pertec to USB project? Might be interesting to get access to old tapes on more modern computers? Thanks all! 73 Eugene W2HX

I am curious about how well it works and which version to get. Depends on the machine and the OS. Worked well in a PowerBook with MacOS, but NetBSD on my IIci threw all kinds of problems with it. Works great in my Solbourne S3000, but opened the SCSI fuse on my rare PowerBook "800." I don't know if v6 is appreciably better. Most of my experience is with v5. Odds are it will work but it's not a panacea, nor (in fairness) is it sold as one.

I have not tried them on as many systems as Josh, but otherwise I have had similar position experiences using them. I have been using them on sun4c and sun4m systems. alan

Re: 2.11 BSD on an 11/93 with an CMD SCSI Module
Bill, Here's the patched boot loader that you need. http://www.chdickman.com/pdp11/rauboot.s The rest is an exercise for the student. :-) Its about the journey, not the destination, otherwise we would be somewhere else. I have to say that it took a lot of patience to get 2.11BSD running on my first PDP-11/73. I think it was about 3 years before I was able to get the parts together and figure out the method. SIMH didn't have MSCP support and there was a bug in ra boot loader that took a while to fix.

Clearpoint SNXRAM/12 VME
Hey, Anybody happen to have any documentation for a Clearpoint SNXRAM card? I’ll take any version ( though I have the /12 card ). I’m trying to figure out the jumpers on this board. It generates a memory error in my Sun 3/110 but not sure if that’s because of overlapping addressing. I’ve tried searching for the doc for years ( this year I’m trying very hard to get my Sun 2/120 and Sun 3/110 running correctly. Got my Sun 1/100 and Sun 4/110 booting correctly, disk images are almost ready for them ) Earl Sent from my iPhone
