+ADB to USB keyboard converter
+=============================
+http://geekhack.org/showwiki.php?title=Island:14290
+
+This firmware converts ADB keyboard protocol to USB.
+
+
+Build
+-----
+0. Connect ADB keyboard to Teensy by 3 lines(Vcc, GND, Data).
+   You need a external pull-up resistor on DATA line in most case,
+   in particular when you want to use a long or coiled cable.
+   This converter uses AVR's internal pull-up, but it seems to be too weak.
+   The external pull-up resistor is strongly recommended.
+   PSW line is optional. See ADB.txt for details.
+1. Define following macros for ADB connection in config.h:
+   ADB_PORT
+   ADB_PIN
+   ADB_DDR
+   ADB_DATA_BIT
+   ADB_PSW_BIT
+2. make
+3. program Teensy.
+
+
+Keymap
+------
+You can change a keymap by editing code of keymap.c like following.
+This is a keymap for AEK, however, also used for other keyboards.
+How to define the keymap is probably obvious. You can find  key
+symbols in usb_keycodes.h.
+If you want to define some keymaps than just one, see hhkb/keymap.c and
+macway/keymap.c as examples. Keymap(layer) switching may needs a bit of
+effort at this time.

+Notes
+-----
+Many ADB keyboards has no discrimination between right modifier and left one,
+you will always see left control even if you press right control key.
+Apple Extended Keyboard and Apple Extended Keyboard II are the examples.
+Though ADB protocol itsef has the ability of distinction between right and left.
+And most ADB keyboard has no NKRO functionality, though ADB protocol itsef has that.
