A small operating system for hand made electronic chess boards Based on the work of : https://sites.google.com/view/berger-projects/en/other-repairs-projects/soluschess and http://sishchess.blogspot.com/2012/03/
Made to be as simple as possible and as cheaper as possible for those who love chess but have no money to buy a costly usb chess board.
