Welcome !
view on some machines and peripherals

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-11/04   PDP-11/24   PDP-11/34C   PDP-11/44   PDP-11/60   PDP-11/84   PDP-11/94
(very "blinkenlight" consoles)
(moderate exciting consoles)
  • PDP-11/03   µPDP-11/23   PDP-11/23 PLUS   µPDP-11/53   µPDP-11/73  µPDP-11/93
  • DECstation 2100   DECstation 3100
  • VAXserver 3100   µVAX-II   microVAX 3800   4000VLC
  • VAX-11/750
  • VAX4000-200   VAX4000-500
How to navigate this PDP-11 site.
Using the "radar" section at the left you can navigate 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 an overview of the tree, best practice is to keep the number of opened folders low.
Below the "radar" section you find a "chain" to a page that contains links to other sites with PDP-11 interests. Above the "radar" section is 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 ...

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!

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 responsibility for the information presented on this site.

If you appreciate this website for its information and above all for its cleanliness (no advertising junk or annoying pop-ups), please consider a small donation to cover costs of the hired domain and storage. Feel free to enter any amount. Just 1 dollar would be great. My PayPal id is henk.gooijen@hotmail.com .   Thanks for your support!
