TODO:
- Add support for PF01 - PF24
Emulation file for Keytronic KB3270/PC keyboard by Wilbert Pol.
This keyboard supports both the PC/XT and the PC/AT keyboard protocols. The
desired protocol can be selected by a switch on the keyboard.
Keyboard matrix.

The 'Return', 'Backspace, 'Pad 0', 'Right Shift', 'Pad +' keys on the keyboard
are attached to two switches. The keys appear twice in the keyboard matrix.
