# Amiga 1200 Keyboard Converter

Modification of the Model-M 101 membrane adapter (converter/modelm101) to work with Amiga 1200 keyboard (and possibly Amiga 500/600 too). 
The adapter allows using the original Amiga keyboard as a USB input device, either with a desktop PC or a R-Pi/FPGA board hosted inside the Amiga case.

Available for three micros: AT90USB1286 (Teensy 2++ board), Atmega32u4 (MiSS-1200 FPGA board), and Atmega16u4 (MiSTress-1200 conversion kit).

A small PCB adapter is needed for connecting the keyboard membrane to the Teensy 2.0++ board. A very simple example of such a board is available here:
https://github.com/8bits4ever/A1200-Keyboard-Adapter

The MiSS-1200 FPGA board and MiSTress-1200 conversion kit both feature a dedicated connector for the Amiga 1200 membrane keyboard.

Files have been modified in accordance to the Amiga keyboard layout and features. A second layer has been implemented (momentary toggle "Help" key) to access unexistent keys (like F11 and F12). This is a work in progress.

* Keyboard Maintainer: [8bits4ever](https://github.com/8bits4ever)
* Hardware Supported: Teensy 2.0++ board by PJRC, MiSS-1200 FPGA by 8bits4ever
* Hardware Availability: https://www.pjrc.com/store/teensypp.html

For first time flashing use the reset button to enter in bootloader mode. Once the board is flashed you can use "HELP"+"R" on the Amiga keyboard for reflashing.  

Make example for this keyboard (after setting up your build environment):

    make converter/a1200/teensy2pp:default

Or:

    make converter/a1200/miss1200:default

Or:

    make converter/a1200/mistress1200:default
