I managed to snag a nice 32s off of "the auction site." It's got a couple of scratches on the bezel that kept the collectors from bidding it up too high, and everything works. So far I'm very pleased. I *love* the Pioneer form factor and keys.
I don't have a manual yet, so I downloaded HPs PDFs of the 32sii and 33s manuals to figure things out. I was fooling around with the RPN solver and the TVM equation Jeff Kearns posted last month (thanks, Jeff!). And something dawned on me.
The 33s has 32K of memory. People have balked because it has the same limited number of variables and labels as its ancestors. But then I realized what the memory is for--equations.
It takes a lot of equations to make much of a dent in that 32K, right? You can easily store variations of your most-used equations to solve for the variables you need, and run them directly, without ever having to use the Solver. Meanwhile, you've still got plenty of program space when you need it.
Now, if only we could retrofit a 32K memory chip in 32s and 32sii. And all the best calculators could benefit from a a USB port to plug in an SD card reader/writer for backup and restore. I know the latter will never fly on the current models due to the exam certification requirements. But hey,I can dream, can't I?
