Any pcb designs/kits to turn X40 keyboard+TP into USB or PS/2?
Any pcb designs/kits to turn X40 keyboard+TP into USB or PS/2?
I was thinking on using X40 keyboard & trackpoint as external (for an SBC like raspberry, for example). Unfortunately all the accompanying electronics is on the motherboard! Does anybody know if there are some magical PCB designs/kits that would have the proper matching socket (2x22 pins, keys and TP) on its one end, and some standard plug (USB or PS/2) on the other end?

Here's the blog of the developer of that Thinkpad USB keyboard adapter: https://flashandrc.wordpress.com/
Of particular interest are the schematics:
USB-only version: https://flashandrc.files.wordpress.com/ ... v0-6-2.pdf
Aborted USB/Bluetooth version: https://flashandrc.files.wordpress.com/ ... sb_kbd.pdf
