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

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.

Prior to 1972 I used a K&E and then a Pickett & Eckel slide rule and a Smith
Chart calculator slide rule.

But I purchased an HP-35 when it first came out. Then the HP-45, and a 55 that
had a neat timer. After retiring in 1980 I purchased the HP-34C and the 15C. One
of my sons worked for HP for 25 years, and while there he purchased two HP-42S,
one for me. They all go with me wherever I go.

I tried to use someone elses TI one time, but after using RPN I couldn't make
the darn thing work. The RPN works just like writing down the problem and
solving it with a pencil.

That Polish guy Lucashowicz (sp?) is my hero!

I have the same problem. I either make stupid mistakes or just plain
can't use non-RPN calculators.

On my Palms I use MathU Pro. Looks like an HP calculator, although one
that has never been made by HP. Works quite well. It is not free, but
is very cheap.
