My HP 10bII+ is much faster than HP 12c!

I tried a few other models for kicks.

Sharp EL-738: Returns 3.65 after displaying "calculating!" for a second or two. I can't seem to get it to find the other solution by storing I% around 100.

Sharp EL-533: Screen goes blank for about 5-10 seconds, and it returns 3.65. I also can't get this one to find the other answer.

Casio fc-1000: Immediate "Ma ERROR".

TI "The MBA": Screen blanks out for a rather long time while it crunches numbers, and it returns a nonsensical 2.99968168. (Note that my unit is acting a little flaky, so this might not be a good data point.)
