I built the PiDP-11 during Covid when stuck at home. I had basically zero soldering experience so I bought a $10 soldering practice kit online first, but other than that it's doable by anyone. It was super fun. I had to take it apart later when I had a set of LEDs that wouldn't work and poked around until I found a solder I had messed up. That was also fun. It sits in my office running blinkenlights most of the time these days - anyway would recommend buying one of these kits!
Edit: I'd guess it took about 6 hours for me to finish over the course of several days, if you are good at soldering it will be cheaper. I stopped a lot to double check stuff like polarity on the LEDs (I think it was LEDs) and what-not.

It was developed for embedded systems and was the first single-chip microprocessor developed by DEC. It was sold on the open market." https://en.wikipedia.org/wiki/PDP-11#Special-purpose_versions https://en.wikipedia.org/wiki/PDP-11#Special-purpose_version...

- wdfx 2y agoI have a couple of J11 chips and wondering what to do with them. Are they just display pieces now, or can they actually be hooked up to modern MCUs and do some "useful" computing?
