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/qmk/qmk_firmware.git
Article: http://geekhack.org/index.php?topic=27272.0

Connection

Keyboard	ATMega32U4
Data	PD2
Clock	PD5

And VCC and GND, of course. See Resource section for keyboard connector pin assign.

Build

git clone https://github.com/qmk/qmk_firmware.git
cd qmk_firmware
make converter/ibm_terminal:default
