I have an MDB Systems workalike LSI-11 backplane which I am starting to get working. I thought it would be nice to build the DBCOK logic and console switches to have the same look and feel as the original PDP-11/03 console so I scripted up the specific DEC switch paddle and LED receptacle as part of the project (which is ongoing) so they can be 3D printed and use a tiny Arduino to do the powerup sequence.

If you have a PDP-11/03 or a PDP-11/05 with missing or broken switch paddles then ...

Racking an old PDP-11 or its peripherals can take some care, owing to the weight and bulk. The task can be made easier with this simple equipment lifting cart you can build. You can quickly, easily and accurately rack, unrack and move heavy gear with confidence - and possibly save your back as well.
