LINDY KVM Switch PRO, anyone has any pic of the mobo?

[legacy]

I am considering commercial KVM switch for a project. LINDY KVM Switch PRO looks interesting because it has all the connector on the same side, it's small size, and it has four buttons.

But I'd like to know what is used on the motherboard, which mux, and which controller.

e.g. on some Dlink KVM-switches I have recently seen the EM78p447, or some 8051 chip.
