RE: Calculator benchmark
Neat! I'm going to have to get me one of these HP-28s..

I think they broke this to some degree in the HP-49G+, unless the exact solver is still available in it somewhere that I haven't found. In the NUM.SLV / "Solve equation" screen, you can enter the equation (if you hadn't STEQ'd it already), have it query for the variables, and you can hit "EXPR=" (on of the F keys) to evaluate the sides. But the results are not shown until you leave the solver (press ON, then shows left and right).

Update: yeah I checked this in emu48. C.Ret's solution works on the HP-48S and HP-48SX, but does not work on HP-48G. The "improved" solver on the graphing calculators breaks it.

On some calculators you can make two equations into one by using complex numbers: one equation is real, the other is imaginary. Maybe there is something with vectors to extend this further..
