All I want for Christmas is a PDP-11/93! Merry Christmas, all!:xmas: -Ken

Hello DECheads, Perhaps my google'ing skills are lacking, but I can't seem to come up with any design worthy documentation for the FPJ11, the floating point chip companion to the DCJ11. For most, it's just a socket on the CPU board that you plug the part into and I understand. The best so far...

Hello again DECheads, I've noticed what seems to be an increasing interest in prototyping hardware for the Qbus. I, for one, am tinkering on a Qbus processor board as is Peter (cbscpe on VCFED). There's also a recent VCFED post by w3llschmidt indicating a need for Qbus design templates. I'm...

Hi DEC Forum Folks, As a part of my earlier posted "World's Fastest Real DCJ11" project I recently realized that I needed a few DL software compatible serial ports, so I re-investigated the once prolific DC319 that I designed into numerous products way back when. Although I have a few dusty...

Hello, y'all, Does anyone have an idea of what the color codes are that DEC used for the PDP? I have an old 11/23 front panel and would like to repaint it for a project. Or, has anyone found a close match in a commercial paint? -Ken

Hello All DEC Heads (Sounds a bit off, but I'll employ creative license), It's been a while since I've had time to post here, but I do follow along when I can. One of my supervised "job jar" activities today was cleaning out a bin with many boxes of my past business documents. There, I came...

Hello everyone in DECland, My wife says I'm crazy on a regular basis, but I need my papers to prove it. So, simply put, I'd like to build it. Yes, the world's fastest PDP-11. I'm not talking about emulators, I'm talking about a DCJ-11 clocking along at 20+ megahertz! How fast can it go? How...

In my recent thread "Vintage Custom DCJ-11 based Single Board Computer" I alluded to designing with a microVAX at one point in my circuit design history. The DEC product I was referencing was an rtVAX300. Anyone ever heard of it? Probably very few folks that do. Well, sometime in the early '90's...

Hello to all that are unselfishly keeping DEC vintage iron alive. I salute you. I'm a retired hardware engineer that designed a number of single board computers beginning in the '80s based on the DCJ11 and later the microVAX and then the Alpha 21164. I guess I'm getting nostalgic (or worse), but...
