If you are interested in old computer technology, especially the PDP-11 from Digital Equipment Corporation, in short "DEC", I would like to invite you on a tour along my vintage Digital PDP-11 computer systems. In the future, I hope these pages will become a source of information on the hardware presented here, right down to the jumper settings of the boards with clear pictures of them. Of course there will be pictures of all the devices and of the complete systems.
Due to room restrictions (recognizable by many collectors), I have these systems at this moment:

PDP-11/05 , PDP-11/10 , PDP-11/20 , PDP-11/35 , PDP-11/45 , PDP-11/55 , PDP-11/70 PDP-11/34C , PDP-11/44 , PDP-11/60 , PDP-11/84 ,  PDP-11/94

(very "blinkenlight" consoles) (moderate exciting consoles)

µPDP-11/53 ,  µPDP-11/73 ,  µPDP-11/93 (sold to finance the 11/70) DECstation 2100 , DECstation 3100 VAXserver 3100 , µVAX-II , 4000VLC VAX-11/750

How to navigate this PDP-11 site.
The "radar" section at the left offers navigation through this site; just click on the folder. Clicking on the name next to a   folder   gives general information, but does not open the folder. To open the folder you must click on the folder itself. To keep a clear overview of the tree, best practice is to keep the number of opened folders low.
Clicking a link called "HOME page" or clicking on the "welcome" folder icon in the "radar" section takes you back to this page.
On top of the "radar" section you find a "chain" to a page that contains links to other sites with PDP-11 interests, and a link to the "update status" of this site.
You can also enter a keyword in the "Google" form and hit "Enter" or click on one of the checkboxes below the query entry line ...

Rationale.
These pages are written to give a bit more feeling for technology advances in the past 30 years, or should I say: more respect for the early machines. Also, for the lucky ones among us who own such a system, I hope to give information on installation and configuration, diagnostics, etc. although this is restricted to the documentation and systems I have.
Suggestions, questions and remarks are welcome. I hope you enjoy this site!

Disclaimer.
I am not perfect, so there could be errors in my texts and drawings. Especially, double check the positions of the location of boards in a backplane; use another site or ask!  I do not take any responsibilty for the information presented on this site.
