You Xiaojie / 尤晓杰 494faeb488 Correct the comments of matrix ROW and COL. (#604) 
according to the code:
static uint8_t matrix[MATRIX_ROWS];
#define ROW(code)      (code>>3)
#define COL(code) (code&0x07)
in converter/terminal_usb/matrix.c
ROW is decided by bits 7-4 of scancode
COL is decided by bits 2-0 of scancode

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).

CONNECTION
----------
Keyboard    ATMega32U4
----------------------
Data:       PD0
Clock:      PD1

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


BUILD
-----
$ git clone https://github.com/tmk/tmk_keyboard.git
