-Alternative 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.
-- Power key couldn't be used because power key is not connected to controller.
-
-History
-=======
-- 2012.09.17 First Release
-
-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. Refer doc directory
-
-To Do
-=====
-0. Caps Lock connect
-1. Layer Change by toggling Clear Key
-2. Eject Key add. (following files should be modified.)
