+Keyboard converter for IBM terminal keyboard
+============================================
+It supports PS/2 Scan Code Set 3 and runs on USB AVR chips such like PJRC Teensy.
+I tested the converter on ATMega32U4 with 1392595(102keys) and 6110345(122keys).
+
+Source code: https://github.com/tmk/tmk_keyboard
+Article: http://geekhack.org/index.php?topic=27272.0
+
+
+CONNECTION
+----------
+Keyboard ATMega32U4
+----------------------
+Data: PD2
+Clock: PD5
+
+And VCC and GND, of course. See RESOURCE for keyboard connector pin assign.
+
+
+BUILD
+-----
+$ git clone https://github.com/tmk/tmk_keyboard.git
