You could create a robot to type on the keys.
Or connect a lot of wires to the keyboard's contacts and operate one small =
relay for each key.


Perhaps the simplest approach is just skipping the direct connection to
the keyboard and feeding your data through an USB port by means of a
circuit that emulates an additional keyboard. Your PIC will not be able
to do that, you need a PIC with USB interface.

"Something"? Do you know what is it for? If you don't, well, you need to re=
ad a lot.

You have too much homework to do before anybody can help you.
