RLM-12CX Finance & Business Calculator

The RLM-12CX calculator is an extensive set of tools and enhancements inspired in the real HP-12C calculator. It works in the same way, but expanded with 15 digits precision, 100 store registers, 1000 program steps and a complete set of menus to handle almost any financial and business problem (toggle tapping the "OPT" key). Also, the Display was expanded to show all the Stack registers and, in landscape orientation, the content of the financial registers, storage registers and program memory.
