I had some time off after leaving a long stint as a SysAdmin/SRE/the names changed over the two decades I worked for a prominent Linux distribution company. I spent some of this decompressing and writing Usagi Electric’s now-infamous “Hellorld” exercise for the PDP-12 at University of Minnesota, Duluth.
Since we did a lot of the debugging via videos of scope behaviour and the lights on the console under single-stepping operation, I helped my friend at UMD out by making the video about it for his YouTube channel. I hope you enjoy it!
