Hi Jens, I messaged you a short while back on twitter about a schematic for the a604n and you said it was closed source, which I understand completely.
I wonder if there is some redacted information you can offer. Really I just want to continuity check the pins of the ECS socket to each destination to eliminate, or repair bad solder connection. Of course the bottom side traces are easily visible, but not the hidden or topside traces. If there's any info you can offer I would be grateful. You can DM me in twitter if you'd like to keep any info private. Thanks jim (fuzzweed)
