I don't know about your other requirements, but you could save quite a
brunch of pins using a PC keyboard... you only need 2 pins if I'm not
mistaken. The only problem is that your keyboard routine has to be
quite fast to handle each bit in the serial line... unfortunally it
doesn't work properly when connected to the chip's serial ports...
