Update. Still waiting for my repair components I ordered to show up. In the meantime I’ve been plugging away staring through my microscope and drawing up this little scribble of mine. This scribble is going to be translated into a schematic and then eventually a boardview. Will update when I make progress.
P.S. No word when I’ll ever see the replacement rail module I’m “supposed” to get.
Also, I’m interested in buying a few failed rails if you got your replacement.
