CN14: KB CONN
In the middle of the mainboard there is a spot where a connector can be soldered on. CN14 is also called KB CONN so I think this is a keyboard connector and I thought right. This is indeed a PS/2 keyboard connector which is wired as follow when you hold the main board in such a way you can read the 'KB CONN CN14' printing: GND KBCLK KBDAT VCC These 4 lines can be connected to a PS/2 mini-din connector:
1 KBDAT
2 n/c
3 GND
4 VCC
5 KBCLK
6 n/c
Now the question is, does it work? Only one way to find out so I solder a PS/2 connector to the mainboard with some flatcable as you can see in the pictures. When I boot the webplayer I can see the 3 LED's flash so I suppose it works and indeed it works without any problem. Hey! An other victory 
The IR keyboard that came with the webplayer seems to have a problem with a wired keyboard connected. Some keys have a strange behaviour, but the problem doesn't occur when you type with the wired keyboard.
As I'm typing more I notice that also the wired keyboard has a problem. Probably because the wireless keyboard hasn't have a separate numeric keypad but has to share some other keys on the main pad. Maybe later I will try to deactivate the IR function, just to check if it is possible to do so. Just removing the "IR KB CTRL" chip doesn't work at all. The Webplayer won't boot anymore.
There are two pins from the chip that are connected to the ps/2 signals (pins 16 & 18) so I have just bent them a bit so they wouldn't touch the corresponding pin connector in the chip holder. Now the wired keyboard works just fine without any problems at all. The mouse function of the wireless keyboard keeps working as before.
Until now I haven't been able to connect another mouse on the webplayer. I think the problem is the serial port, but I'll get to that later on.
