Here’s a wonderful intro to a collection of videos and instructional materials from the 1970s on how to program and operate a DEC PDP-11. First, toggle in your loader, then boot from paper tape…. Very cool, in a retro way. I did a lot of PDP-11 stuff back in the mid-70s.
[The videos are accessible on YouTube; the website with the other materials appears to have been brought to its knees as a result of being mentioned in Boing Boing…]
