Wiring matrix for the KB600 series?

[teoh]

Hi @stapelberg,

I really love the work you and the team did here. I understand that kint uses the kinesis' matrix wiring as-is (i.e. no re-soldering of any keys).

Looking at your schematic and qmk firmware, it seems like you had to figure out the matrix wiring for all of the keys at some point.

I have two questions:

1. How did you figure out this underlying matrix wiring? For example, in THUMB_LEFT_BAK_KB600 on your schematic, how did you know the exact FPC connector pins that controlled the rows/cols in that thumb cluster?
2. Do you have this wiring matrix diagram, and is it available to share?

I figured I could take apart and de-solder my whole keyboard to find look at the wiring myself, but I just know I will break it.

Have a look at https://michael.stapelberg.ch/posts/2013-03-21-kinesis_custom_controller/ for some historical context. The linked posts explain the matrix. They can still be read using the Web Archive:
