| | 1 | M0110/M0110A to USB keyboard converter |
| | 2 | ====================================== |
| | 3 | This firmware converts the protocol of Apple Macintosh keyboard **M0110**, **M0110A** and **M0120** into USB. Target of this project is USB AVR controller like **ATmega32U2** and **ATmega32U4**. Using this converter you can revive these retro keyboards with modern computer. |

| | 12 | |
| | 13 | - M0110A support was contributed by [skagon@github](https://github.com/skagon). |
| | 14 | - M0120 also is supported. keys(+ * / and ,) on M0120 are recognized as cursor keys. |

| | 18 | Update |
| | 19 | ------ |
| | 20 | - 2013/08: Change port for signals `PF` to `PD` |
| | 21 | - 2013/09: Change port again, it uses inversely `PD0` for data and `PD1` for clock line now. |
| | 22 | - 2014/06: Change keymaps |
| | 23 | - 2015/03: Add support for "International"(ISO) keyboard(keymap_intl.c) |
| | 24 | - 2016/09: Unimap support - keymap editor on web browser |
| | 25 | |
| | 26 | |

| | 28 | Hardware |
| | 29 | -------- |
| | 30 | You can buy preassembled [TMK converter] or make yourown with AVR dev board like PJRC [Teensy]. |
| | 31 | |
| | 32 | Port of the MCU `PD1` is assigned to `CLOCK` line and `PD0` to `DATA` by default, you can change pin configuration with editing `config.h`. |

| | 51 | ### Pull-up Resistor |
| | 52 | You may need pull-up resistors on signal lines(`CLOCK`, `DATA`) in particular when you have long or coiled cable. **1k-10k Ohm** will be OK for this purpose. In that case the converter may not read signal from keyboard correctly without pull-up resistors. |

| | 56 | Building Firmware |
| | 57 | ----------------- |
| | 58 | To compile firmware you need AVR GCC. You can edit *Makefile* and *config.h* to change compile options and pin configuration. Also `KEYMAP` option can be used to select keymap. |
| | 59 | |
| | 60 | $ git clone git://github.com/tmk/tmk_keyboard.git (or download source) |
| | 61 | $ cd m0110_usb |
| | 62 | $ make -f Makefile.rev2 clean |
| | 63 | $ make -f Makefile.rev2 [KEYMAP={intl|spacefn}] |
| | 64 | |
| | 65 | Use `Maefile.rev1` for TMK converter rev.1 and Teensy(ATMega32u4), instead. |
| | 66 | |
| | 67 | |
| | 68 | |
| | 69 | Keymap |
| | 70 | ------ |
| | 71 | To create your own keymap copy existent keymap file to `keymap_<name>.c` and edit it. You can build with `make -f Makefile.rev2 KEYMAP=<name>`. |
| | 72 | |
| | 73 | Or you can edit keymap on web browser and download firmware. |

| | 78 | Debug |
| | 79 | ----- |
| | 80 | 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 `<Magic>+H` simultaneously to get help. |
| | 81 | |
| | 82 | - Magic combo: `Shift+Option+⌘` or `Shift+Option+Ctrl`(`Shift+Alt+Gui` or `Shift+Alt+Control`) |
