RTFM

The manual for the 19C is on the MoHPC CDROM

For a quick how-to read the RPN article on the HP web site:

But I'm sure you were given some instruction on slide rules. Get a manual for it and it will all make sense. You won't want to go back to calculators with = keys.

Thanks Jim. I was about to ask Don to trade his 19c for a calculator with the "=" key. (I would buy him a brand new one too)

[Dia C. Tran]

I can't help but post again.
A fully functioning HP19C is worth more than any handheld calculator that you can buy new in store today.
So Don do ya wanna trade?

Don, please read about RPN on HP's site, and be sure to check out the explanation of RPN here on hpmuseum.org also.

If you really wanna get rid of it, put it up for sale in the classified's on this site. Otherwise just tough it out and learn RPN for 'fun'. Get a Casio fx260 solar at walmart for $9 to do your everyday math.
