retro_refit keyboard firmware
======================

## Keyboard Info

The retro refit keyboard used a Teensy to replace the original controller on a 386 "laptop".

This keyboard uses a KEYMAP macro that is a great example of using a non-standard row-column matrix. The keyboard in question had 11 rows and 8 columns, but the rows were not all horizontal, and the columns were not all vertical. For example, row 2 contained "Print Screen", "N", "M", ",", ".", "/", "Right Shift", and"Left Alt". Column 0 contained "F6", "7", "O", "'", "Q", "D", "B", "Left Alt", "Up Arrow", and "Down Arrow".

The macro makes programming the keys easier and in a more straight-forward manner because it realigns the keys into a 6x15 sensible keyboard layout instead of the obtuse 11x8 matrix. Each Kxy corrisponds to a key in row x column y.

## Quantum MK Firmware

For the full Quantum feature list, see [the parent readme.md](/readme.md).

## Building

Download or clone the whole firmware and navigate to the keyboards/retro_refit folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file.

Depending on which keymap you would like to use, you will have to compile slightly differently.

### Default
To build with the default keymap, simply run `make default`.

### Other Keymaps
Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `<name>.c` and see keymap document (you can find in top readme.md) and existent keymap files.

To build the firmware binary hex file with a keymap just do `make` with a keymap like this:

```
$ make [default|jack|<name>]
```

Keymaps follow the format **__\<name\>.c__** and are stored in the `keymaps` folder.
