[x] Done. (12C) Solve f(x)=0 with modified Regula Falsi method.

I don't think it has to. Look, the 12C is not a universal tool, it is a specialized calculator for financial applications. That's why it has a very limited set of scientific functions: square root, power, natural log and e^x – and that's it. There is not even an x² key, let alone sin, cos, tan, common log and antilog and others. With the limited ressources of 1981 you could either have a financial calculator with a quite complete function set for such applications, or you could get a more universal scientific device like the 11C. Looking at 37 years of success this seems to have been a quite good decision. ;-)
