This wiki was originally created to be a development home for repurposing the HP-20b calculator, but has since grown to support several repurposing projects. 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. If you know of other repurpose-capable calculators or calculator hacking information that could be interesting to our audience, please add to the wiki.
Everyone is free to read and partake of the information here. Registered users will be able to edit, contribute and participate in all facets of this site. Registration is free, and takes only a few minutes. If you have any suggestions on how to improve this site, please contact me and let me know what you think.
