 # 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.
 
-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 can be seen here:
+Available for two micros: AT90USB1286 (Teensy 2++ board), and ATmega32u4 (MiSS-1200 FPGA board).

-This adapter is meant to allow 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.
+The MiSS-1200 FPGA board features a dedicated connector for the Amiga 1200 membrane keyboard.
 
-Files have been modified in accordance to fit 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.
