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

- 2013/08: Change port for signals `PF` to `PD` |
|

- 2013/09: Change port again, it uses inversely `PD0` for data and `PD1` for clock line now. |

Connection |
|
|
|
---------- |
|
|
|
You need 4P4C plug and cable to connect Teensy or other AVR dev board into the keyboard. |
|
|
|
Teensy port `PD0` is assigned for `CLOCK` line and `PD1` for `DATA` by default, |
|
|
|
you can change pin configuration with editing *config.h*. |

Building Hardware |

|
----------------- |
|
|
|
You need **4P4C** cable and **ATMega32U4** board like PJRC [Teensy]. 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`. |
|
|
|
|
|
|
|
You can find 4P4C plugs on telephone handset cable. Note that it is *crossover* connection |
|
|
|
while Macintosh keyboard cable is *straight*. |

### 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. |
