RPN on TI-89 Titanium
Message #1 Posted by Meenzer on 26 Nov 2007, 12:28 p.m.

As I was just succesfully converting (with Egan Ford's help, thanks) my HP 71B to RPN mode, I thought I'd try something similar on my TI-89 Titanium.

Lars Frederiksen wrote a fast and neat application for the TI-89 (allready reported here some years back), that adds a real RPN mode to that machine. You can even have the algebraic expression being build up alongside in the stack to check for errors.

All necessary links can be found here.
