iBook G4 Clamshell Keyboard pinout?

[sircastor]

This is a longshot in general, but I've seen plenty of folks hacking away at their 1st gen iBooks. Does anybody know what the pinout is for the 40-pin connector that goes from the keyboard to the iBook. The pitch for the pins is ~1mm (I think, these are hand-measurements) I know virtually nothing about how keyboards multiplex values, so I'm hoping someone has done some of the footwork already 😁

Any help is welcome.

As I was poking around, I found someone had already gone through the struggle
Many thanks to @rorydaredking for writing down the exploration process

It's not a pinout specifically - but information and links to data for reading from the keyboard matrix.
