Keyboard fake:

> Most systems detect a keyboard connection by monitoring the current flow
> through the connector.  To trick it, simple wire a 10kohm resistor
> between GND (pin 4) and +5V (pin 5).  This is on a standard PC/AT style
> connector (the larger 5 pin one).  If you have a PS/2 keyboard, you can
> either use an adapter to change it to an AT connector, or use the
> resistor between pins 3 and 4 of tjhe PS/2 adapter.  Note that the
> pinout isn't simply clockwise or counter clockwise:
> 
> PC/AT:
>   n
> 1   3
> 4   5
>   2
> 
> PS/2:
>   n
> 5   6
> 3   4
>  1 2

> as viewed looking into the connector on the keyboard, not the PC.
