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, though, you can use other board with USB AVR like ATmega32U4 and AT90USB.

M0110

  • M0110A support was contributed by skagon@github.
  • M0120 also is supported. keys(+ * / and ,) on M0120 are recognized as cursor keys.

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]

In this pic:

  1. GND(Black)
  2. CLOCK(Red)
  3. DATA(Green)
  4. +5V(Yellow)

Note that wire colors may vary in your cable.

Pinout

Jack fig

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 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 -f Makefile.lufa clean
$ make -f Makefile.lufa

and program your Teensy with PJRC Teensy loader.

Keymap

You can change keymaps by editing keymap.c.

Debug

You can use PJRC HID listen to see debug output.

The converter has some functions for debug, press <magickey>+H simultaneously to get help. These function is totally undocumented, tentative, inconsistent and buggy.

magickey: Shift+Option+Command(Shift+Alt+Gui or Shift+Alt+Control)
