Reckon 1.0 beta released Message #1 Posted by hugh steers on 5 Mar 2009, 1:30 p.m.
Hi, This is not about HP calculators, sorry, but it does have RPN!
As promised a while back, i've released Reckon, a free replacement calculator for the casio fx-9860g.
I've created a page where you can download the latest version and also the PDF manual. The manual explains how to operate it.

I'm quite pleased with the RPN mode. You can temporarily use ALG subexpessions from within RPN, just by opening a bracket "(". This is really handy for entering formulae.
Give it a go!
