PS/2 to USB keyboard converter for IBM terminal keyboard
=========================================================
It supports PS/2 Scan Code Set 3 and runs on Teensy, Teensy++ and boards withATMega32u4/AT90USB.
I tested the converter only on Teensy with 1392595(102keys terminal keyboard), though, I think it will also work with 122keys boards.
CONNECTION
----------
Data: PD0
Clock: PD1
It is same as Soarer's converter pin configuration.

BUILD
-----
For 102keys:
$ make -f Makefile.102_pjrc
For 122keys(not tested):
$ make -f Makefile.122_pjrc
I used WinAVR 20100110 to develop.
