The HP15 had 2 parallel stacks, one for the real parts and one for the imaginary parts. The HP42 had something better: Every stack member could be a real or a complex number. (Conversion (x,y) <> y+i*x: the "COMPLEX" function) The HP42S system is IMO much easier to use. (The same goes for matrix functions, solver and integrals.) JSBach
