I must also plead guilty to the RPN preference.  I use an HP-11C, and still 
have my original HP-25 from 1979.

If you want a decent freeware RPN calculator for the PC, just do a search 
on "Excalibur RPN calculator" and you'll find it quickly.  There is also 
site out there that has the history and specs of many of the classic HP 
models, plus emulators.

And I still have two slide rules, including one that I used in high school, 
and the old wooden German slide rule my father the theoretical physicist 
used in the 40s and 50s.  It's in a drawer with his old Estabrook fountain 
pen and my Osmiroid italic pen with the left-handed nib. I used those pens 
to write music on diazo sheets in the time before music programs on 
personal computers.
