In order, I like my HP15C, HP11C, and way behind HP48SX. And then there
is my HP25.

Tom et al-

You guys are out of my league. Back when I needed a good calculator, I
couldn't afford the new HP-35. By now, I've forgotten how to use the
slide rules in my collection.

I do have a Palm PDA. There is a freeware reverse-Polish program for it
called Kalk by Holger Klawitter. It is available at
http://www.klawitter.de/palm. I doubt it will match the fine HP
instruments you mention, but you may want to have a copy if you spend a
lot of time with your PDA.
