I am jmk, a complete newbie here.
It is odd that I used to see many comments and discussions here, but suddenly they are all gone.
Anyway, inspired by hasu's mod of m0110, I also tried to do the mod in a slightly different but fundamentally the same way.
But I encountered a problem with figuring out pinout and connection between the keyboard and teensy.
I sent hasu a message, and he thinks it is better to discuss it publicly. So here is my question and hasu's answer.
I asked about the arrangement of the color of 4p4c because 4p4c is usually crossover-wired. So, for example, yellow can be either +5V or GND (to put is another way, it can be either #4, or #1)
Images below are the messages that I traded with hasu

I hope this helps someone who has the same issue like me.
As I do the mod, I will post my questions and solutions.
