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.)
|
||||
common/usb_keycodes.h
|
||||
