It is our hope that this grass-roots approach to calculator hacking will expand to include other many HP calculator models and open-source projects. We have configured this wiki so that it supports all HP calculators and projects, and any and all new projects are welcome.

These aren't bug fixes in any sense; rather, they are small pieces of code that change the behaviour of the WP 34S calculator in various ways. I've made them to make my favourite calculator even better (at least, from my point of view!)
