Beige-O-Vision just made a very nice 4-part Youtube movie showing how to build the PiDP-11. Worth mentioning here, as it surely will save builders a lot of time. Since nobody reads written Building Instructions anymore these days...

The next three parts as Youtube links:

Part 2 (soldering), Part 3 (mounting the switches), Part 4 (wrapping up)

Thank you, Beige-O-Vision!
