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!
