chessoclock is a simple chess clock running on a virtual terminal. It
supports an user defined time amount and increment per move as well as extra time and all the features of a Fischer clock.
chessoclock is no longer based on the curses library. Install it on your
(even old old old) laptop and you can have a chess clock everywhere in every moment. Under Linux only it can run in a xterm, but you get best visual effect when running in a virtual terminal or on the console and not under X.
Merging chessoclock and a Minix 2.0.4 root disk gives us chessoflop.
Use chessoflop to turn your twenty years old 80286 into a chess clock without installing anything. Reverse the image on a floppy, put that disk on your old computer, turn it on and that’s all!
chessoflop image is available in the download page (it's the one all capitalized).
