RLM-15CX Scientific Calculator

The RLM-15CX calculator is an extensive set of tools and enhancements inspired in the real HP-15C calculator. It works in the same way, but expanded with 15 digits precision, 999 program steps and a complete set of menus to handle almost any scientific, financial or business problems (toggle tapping the "OPT" key). Also, the Display was expanded to show all the Stack registers and, in landscape orientation, the content of the storage registers, flags, statistic register, matrices and program memory.
