+Replacable USB Controller for Apple IIgs/Standard(M0116)
+JeffreySung(nattyman@gmail.com)
+
+===============================
+
+Feature
+-------
+- Replaceable keyboard controller for Apple IIgs(A9M0330)/Standard(M0116)
+- Teensy++ 2.0 required
+- Some signal bypass required
+- ADB keyboard doesn't use matrix for modifier keys. With virtual row for modifier keys,
+ these keys are merged into key matrix using virtual row.
+
+History
+=======
+- 2012.09.17 First Release
+- 2012.09.17 CapsLock support
+- 2012.09.19 Power button added
+Build
+=====
+0. Just Type "Make" and return.
+
+Hardware
+========
+PJRC Teensy
+-----------
+0. The following ports should not be connected to board.
+ From top view of Teensy++, from GND and counter clock wise.
+ -7,26(in keyboard PCB, these pins are VDD,GND)
+ -30,31(in Teensy++, these pins are Ref,GND respectively)
+ -5,6(D2,D3 for bluetooth in future)
+1. Bypass #31 pin(from board) to E4(Teensy)
+2. Bypass #30 pin(from board) to F2(Teensy)
+3. Bypass #6 pin(from board) to A0(Teensy)
+4. Refer doc directory
+
+To Do
+=====
+0. When DEBOUNCE defined, there is a errors.
+1. Layer Change by toggling Clear Key
+2. Eject Key add. (following files should be modified.)
+ common/keycode.h
+ common/keyboard.c
+3. Use bluetooth
