Embla is a chess program. It plays chess, e.g. generates the moves. It is not a board or so.
For the people who are afraid of red, yellow, blue and computers, there's now a solution: I made a small box combining a small keyboard these, an even smaller display (a 7110 by Nokia) and a raspberry pi zero.
The raspberry pi zero boots up with the SD card in read-only mode (to prevent SD-damage caused by an unclean shutdown) and starts a small python script. This python script talks the UCI protocol understood by Embla and then interfaces the keyboard, the display and the chess program.
