+ADB to USB keyboard converter
+=============================
+http://geekhack.org/showwiki.php?title=Island:14290
+
+This firmware converts ADB keyboard protocol to USB.
+
+
+Build
+-----
+0. Connect ADB keyboard to Teensy by 3 lines(Vcc, GND, Data).
+   You need a external pull-up resistor on DATA line in most case,
+   in particular when you want to use a long or coiled cable.
+   This converter uses AVR's internal pull-up, but it seems to be too weak.
+   The external pull-up resistor is strongly recommended.
+   PSW line is optional. See ADB.txt for details.
+1. Define following macros for ADB connection in config.h:
+   ADB_PORT
+   ADB_PIN
+   ADB_DDR
+   ADB_DATA_BIT
+   ADB_PSW_BIT
+2. make
+3. program Teensy.
+
+
+Keymap
+------
+You can change a keymap by editing code of keymap.c like following.
+This is a keymap for AEK, however, also used for other keyboards.
+How to define the keymap is probably obvious. You can find  key
+symbols in usb_keycodes.h.
+If you want to define some keymaps than just one, see hhkb/keymap.c and
+macway/keymap.c as examples. Keymap(layer) switching may needs a bit of
+effort at this time.

+Notes
+-----
+Many ADB keyboards has no discrimination between right modifier and left one,
+you will always see left control even if you press right control key.
+Apple Extended Keyboard and Apple Extended Keyboard II are the examples.
+Though ADB protocol itsef has the ability of distinction between right and left.
+And most ADB keyboard has no NKRO functionality, though ADB protocol itsef has that.

+M0110/M0110A to USB keyboard converter
+======================================
+This firmware converts the protocol of Apple Macintosh keyboard M0110/M0110A into USB.
+Target board of this project is [PJRC Teensy](http://www.pjrc.com/teensy/), though,
+you can use other board with USB AVR like `ATmega32U4` and `AT90USB`.
+
+![M0110](https://github.com/tmk/tmk_keyboard/raw/master/m0110_usb/doc/m0110.jpg)
+
+M0110A support was contributed by [skagon@github](https://github.com/skagon).
+
+
+
+Connection
+----------
+You need 4P4C plug and cable to connect Teensy or other AVR dev board into the keyboard.
+Teensy port `PF0` is assigned for `CLOCK` line and `PF1` for `DATA` by default,
+you can change pin configuration with editing *config.h*.
+
+You can find 4P4C plugs on telephone handset cable. Note that it is *crossover* connection
+while Macintosh keyboard cable is *straight*.
+
+[![Conection](http://i.imgur.com/vJoVOm.jpg)](http://i.imgur.com/vJoVO.jpg)
+
+In this pic:
+
+1. `GND`(Black)
+2. `CLOCK`(Red)
+3. `DATA`(Green)
+4. `+5V`(Yellow)
+
+Not that wire colors may vary in your cable.
+
+
+### Pinout

+- <http://en.wikipedia.org/wiki/Modular_connector#4P4C>
+
+![Jack fig](http://www.kbdbabel.org/conn/kbd_connector_macplus.png)
+
+
+### Pull-up Registor
+You may need pull-up registors on signal lines(`CLOCK`, `DATA`) in particular
+when you have long or coiled cable. 1k-10k Ohm will be OK for this purpose.
+In some cases MCU can't read signal from keyboard correctly without pull-up resistors.
+
+
+
+Building Frimware
+-----------------
+To compile firmware you need AVR GCC. You can use [WinAVR](http://winavr.sourceforge.net/) on Windows.
+You can edit *Makefile* and *config.h* to change compile options and pin configuration.
+
+    $ git clone git://github.com/tmk/tmk_keyboard.git (or download source)
+    $ cd m0110_usb
+    $ make
+
+and program your Teensy with [PJRC Teensy loader](http://www.pjrc.com/teensy/loader.html).
+
+
+
+Keymap
+------
+You can change keymaps by editing *keymap.c*.

+Debug
+-----
+You can use [PJRC HID listen](http://www.pjrc.com/teensy/hid_listen.html) to see debug output.
+
+The converter has some functions for debug, press `Alt+Gui+H` simultaneously to get help.
+These function is totally undocumented, tentative, inconsistent and buggy.

+PS/2 to USB keyboard converter
+==============================
+This firmware converts PS/2 keyboard protocol to USB and for now supports only Scan Code Set 2.
+This will works on USB AVR(ATMega32U4, AT90USB) or V-USB.
+
+
+Features
+--------
+Mouse keys
+    You can emulates mouse move and button click using keyboard.
+System/Media control
+    You can sends Power event, Volume down/up and Mute.
+USB NKRO(actually 120KRO+8Modifiers)
+    You can tolggles NKRO feature.
+Keymap customization
+    You can customize keymaps easily by editing source code. See keymap.c.
+
+
+PS/2 signal handling implementations
+------------------------------------
+Following three methods are used to implement PS/2 signal handling.
+a. Simple and stupid wait & read loop(intensive use of cycles)
+    This is implemented with (expected) portable C code for reference. See ps2.c.
+b. Interrupt driven
+    See ps2_intr.c
+c. Using USART hardware module(no cycle needed)
+    This uses AVR USART function to recevie PS/2 signal and be used in V-USB converter.
+    See ps2_usart.c.
+
+
+Build Converter
+---------------
+Connect PS/2 keyboard into Teensy with 4 lines(Vcc, GND, Data, Clock).
+For a. Simple and stupid and b. Interrupt implementaion:
+    By default Clock is on PF0 and Data on PF1.
+    You can change this pin configuration by editing config_pjrc.h.
+    In this photo Vcc is yellow, GND is green, Data is red and Clock is black.
+    http://img17.imageshack.us/img17/7243/201101181933.jpg
+For c. USART implementation:
+    In case of Teensny(ATMega32u4) CLock is on PD5 and Data on PD2.
+
+
+Build Frimware
+--------------
+1. Edit Makefile for build options and MCU setting.
+    Use 'atmega32u4' for Teensy 2.0 or 'at90usb1286' for Teensy++ 2.0.
+2. make
+    Just type 'make' in a terminal.
+    Use '-f Makefile.pjrc_intr' option to use b. Interrupt.
+    Use '-f Makefile.pjrc_usart' option to use c. USART.
+    Use '-f Makefile.vusb' option to build V-USB converter.
+3. program with Teensy Loader.
+    http://www.pjrc.com/teensy/loader.html
+
+
+Demonstration of Features
+-------------------------
+In default configuration, you can try several keymaps, mousekeys and USB NKRO.
+Use following magic key combinations to enable some features.
+
+keymaps and NKRO:
+    Magic+0:    Qwerty with mousekeys(default)
+    Magic+1:    Qwerty without mousekeys
+    Magic+2:    Colemak
+    Magic+3:    Dvorak
+    Magic+4:    Workman
+    Magic+N:    toggles NKRO/6KRO(6KRO by default)
+    Magic+Esc:  sends Power Event(Power button)
+
+    where Magic=(LShift+RShift) or (LControl+RShift)
+
+Fn layer function:
+    Fn0+(hjkl): Mousekey move(vi cursor like)
+    Fn0+(yuio): Mouse wheel(left,down,up,right)
+    Fn0+space:  Mouse left button
+    Fn0+(mnb):  Mouse buttons(m=left, n=right, b=middle)
+    Fn0+(zxc):  Media control(Volup, Voldown, Mute)
+    Fn1+(hjkl): Cursor move(vi cursor like)
+    Fn1+(nm,.): Cursor move(Home,PageDown,PageUp,End)
+
+    where Fn0=;, Fn1=/
+
+
+Keymap
+------
+You can change a keymap by editing code of keymap.c like following.
+How to define the keymap is probably obvious. You can find  key symbols in usb_keycodes.h.
+To define keymap layer switching may needs a bit of your effort at this time.

+V-USB Support
+=============
+You can also use this converter on ATmega(168/328) with V-USB instead of Teensy.
+The converter on V-USB lacks some features for now: USB NKRO and System/Media control.
+
+To build a firmware use Makefile.vusb instead of Makefile.

+ * runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
+ * information about this function.
+ * Descriptor handling is configured through the descriptor's properties. If
+ * no properties are defined or if they are 0, the default descriptor is used.
+ * Possible properties are:
+ *   + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
+ *     at runtime via usbFunctionDescriptor(). If the usbMsgPtr mechanism is
+ *     used, the data is in FLASH by default. Add property USB_PROP_IS_RAM if
+ *     you want RAM pointers.
+ *   + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
+ *     in static memory is in RAM, not in flash memory.
+ *   + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
+ *     the driver must know the descriptor's length. The descriptor itself is
+ *     found at the address of a well known identifier (see below).
+ * List of static descriptor names (must be declared PROGMEM if in flash):
+ *   char usbDescriptorDevice[];
+ *   char usbDescriptorConfiguration[];
+ *   char usbDescriptorHidReport[];
+ *   char usbDescriptorString0[];
+ *   int usbDescriptorStringVendor[];
+ *   int usbDescriptorStringDevice[];
+ *   int usbDescriptorStringSerialNumber[];
+ * Other descriptors can't be provided statically, they must be provided
+ * dynamically at runtime.
+ *
+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE   (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
+ *
+ * The following descriptors are defined:
+ *   USB_CFG_DESCR_PROPS_DEVICE
+ *   USB_CFG_DESCR_PROPS_CONFIGURATION
+ *   USB_CFG_DESCR_PROPS_STRINGS
+ *   USB_CFG_DESCR_PROPS_STRING_0
+ *   USB_CFG_DESCR_PROPS_STRING_VENDOR
+ *   USB_CFG_DESCR_PROPS_STRING_PRODUCT
+ *   USB_CFG_DESCR_PROPS_STRING_SERIAL_NUMBER
+ *   USB_CFG_DESCR_PROPS_HID
+ *   USB_CFG_DESCR_PROPS_HID_REPORT
+ *   USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
+ *
+ * Note about string descriptors: String descriptors are not just strings, they
+ * are Unicode strings prefixed with a 2 byte header. Example:
+ * int  serialNumberDescriptor[] = {
+ *     USB_STRING_DESCRIPTOR_HEADER(6),
+ *     'S', 'e', 'r', 'i', 'a', 'l'

+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.
+
+http://geekhack.org/showwiki.php?title=Island:27272
+
+
+CONNECTION
+----------
+Data: PD0
+Clock: PD1
+VCC and GND, of course.
+
+It is the same as Soarer's converter pin configuration.
+See RESOURCE for keyboard connector pin assign.
+
+
+
+BUILD
+-----
+Get source:
+$ git clone https://github.com/tmk/tmk_keyboard.git
+$ cd terminal_usb
+
+For 102keys:
+$ make -f Makefile.102_pjrc
+
+For 122keys(not tested):
+$ make -f Makefile.122_pjrc
+
+I used WinAVR 20100110 to develop and build.
