The code is mostly unchanged, and bit-rotting away. – It now lives inside a virtual machine because I got tired of fighting with X11 fonts and PerlTK setup.
The only new feature it gained since 2006 is the last-minute support for

The code with slightly more up-to-date documentation can be found here
You'll still need the Hardware to manage the buzzers – see the old post for more info about that part.
The question files are not public, just because we want to have the option to recycle some questions now and then.
