Did another reverse engineering project, this time on an old Apollo-era PCB that Engineering and Aerospace nerd Skyhawkson obtained earlier in the year. He did all the hard work, tracing out the nets and identifying the parts. I ran into this project and couldn’t resist trying to arrange all the components and try to make sense of the circuitry.
Of note on this project was the use of a dummy PCB design which I used as a placeholder to store the netlist while I was rearranging the schematic symbols. Here’s a writeup I did about it, and the accompanying GitHub repository, and Skyhawkson’s groundwork and photos.
