GoKawiilCommunity driven The C47 project is actively maintained by a dedicated team of calculator aficionados aided by a large and like-minded community of users and enthustiasts on the SwissMicros forum. Get involved! The team would love to hear from you!
RPN based Remember the legendary HP calculators with the big ENTER key? They were indispensible number crunching tools and at least as cool as any of the smart devices of today. Once you get the hang of it, it is one of the most efficient and fun ways to do your math.
Real hardware The C47 software runs on the SwissMicros DM42/DM42n hardware and requires only a custom bezel to transform it into a fully fledged and professional looking C47 calculator. No stickers or changes to the keyboard. Get your bezel here.
Documentation The C47 calculator has an extensive documentation database which is deeply integrated with the development process and also serves as the source of generated PDF documents available here. In addition to this there is a community driven wiki available here.
Source code The source code for the C47 calculator project is on GitLab. Feel free to fork it, learn it, have fun with it. If you come up with a bugfix or a brilliant new feature, send us a merge request and we might include it in the code.
