Dagnamit, I am tempted to sell you mine...........but not sure as I dont want to leave my A4000 bare.
I do however have an Adaptor that lets you use PC keyboards. Its From Mr Hardware..I can sell you that today if you send me Western Union Money Transer........I Also have a Mr Myza Mouse adaptor that lets you use PC mice including Wireless Mice!
The PC keyboard adaptor also lets you use Wireless PC keyboards.......they are both excellent.
