Ergonomic keyboard by Microsoft modified to work with Teensy 2.0.
Move to this directory and run make:
$ make
Only keyboard with US/UK layout was traced. The US matrix ribbon cable had the following writing:
SN5822 US 852-41441-00A V0.4 GODA-3 130601
The US/UK controller PCB had the following writing:
SK3360 V1.1 2013/03/18
812-01311-00A
E157925
KB-6160
Original US layout keboard matrix is 8 rows and 18 columns with UK extra keys in () brackets:

Note that original matrix requires 8+18=26 pins on micro-controller and will not work verbatim on Teensy 2.0 because it only has 25 pins.
There are 30 pins on the US layout Sculpt flex cable. Pin 1 is the outermost pin (closest to the rounded corner with the writing) and lines up with the pin marked "1" underneath a triangle on the US controller PCB.

| 29 | n/a (Q1 LED) |
| 30 | GND (LEDs and fn switch) |
To make all keys work on Teensy 2.0 it is best to merge keys on column C and G of orininal matrix (see above). To achieve that simply connect colums C and G to the same pin on Teensy.
Modified matrix will have 8 rows and 17 columns and will require 25 pins:

Note that RALT and RSFT are now sitting on the same column (C).
