The OTG pin is not soldered, sadly. The online, Web browser-based NumWorks workshop is the way to transfer OS-level data between computer and calculator; at least another DFU implementation works fine for transferring OS upgrades. Among the improvements potentially relevant to you, the third-party Omega firmware restores the exact math engine (removed from Epsilon because of stupid standardized tests in some countries), integrates upstream giac as an external app, and provides a RPN app. EDIT: FTR, you can compile and test on a computer before you buy the calculator. |
