Colouring key
pin doesn't exist
pin connects to a ground line
pin connects to a power line
pin is connected to signal line/something else
pin doesn't connect to anything


Using the location of the not-connected pins F3-F8, I was then able to map these pin-numbers back to the RaspberryPi circuit board:
RPi BCM2835 pinout front.png

However these pins are actually under the CPU, and therefore inaccessible as seen in this "xray" picture.

This picture shows what the same area looks like from the back of the board:

I've added a link to the GIMP file I used to create these images to RPi_Hardware in case anybody wants to continue this work...
