-X68000 to USB keyboard protocol converter
-=========================================
-SHARP X68000 is a hobby computer released in Japan.(1987-93)
-http://en.wikipedia.org/wiki/Sharp_X68000
-
-X68000 keyboard has ALPS linear switches.

-Hardware
---------
-Target MCU is ATMega32u4 but other USB capable AVR will also work.
-You can use PJRC Teensy as development board.
-    http://www.pjrc.com/teensy/
-
-Wiring:
-    Mini-DIN            Teensy
-    -----------------------------------------------------

-    pin4   TXD          PD3(TXD) NOTE: Not supported yet.
-    pin5   READY        -
-    pin6   REMOTE       -
-    pin7   GND          GND
-
-
-Firmware
---------
-Build:
-    $ cd x68k_usb
-    $ make
-
-And load the binary to MCU with your favorite programmer.
-If you use Teensy you can load with PJRC Teensy Loader tool.
