+Keyboard converter for IBM terminal keyboard
+============================================
+
+This is a port of TMK's converter/terminal_usb to QMK.
+
+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

+CONNECTION
+----------
+Keyboard    ATMega32U4

+Data:       PD2
+Clock:      PD5
+
+And VCC and GND, of course. See RESOURCE for keyboard connector pin assign.
