I have not tried the system myself or even looked at the mathematical reasons, but just an initial gut feeling based on your numerical values I would say the system is slow to converge numerically. Just rerun the solver again and see if the values get closer to the solution found on the HP50G. EDIT: What I mean is to run the solver using the current values for X Y and Z as your new initial guess. You can also change the max number of iterations in the options. Lastly, you should be able to see the result of each step to at least see if the convergence is slow. Graph 3D  QPI  SolveSys
