Hello,
I have been "playing" with a TI89 today. Interesting calculator, reminds me of Mathematica's user interface.
I understand there is an RPN emulator of some kind for this beast. Is this true? If so, where can I get it?
Thanks in advance.

Another possibility is rpn89, available for download at http://www.ticalc.org/pub/89/asm/math/ However, I have not personally tried this program.

Hello, Thank you. I will give these a try. Do these programs work on the TI84?

I'm afraid they wont unless a specific version is available for that machine. The 89 is technically close to the 92+ and the Voyage 200, driven by a 68000 Motorola processor. The TI84 (and its predecessors TI80, 81, 82, 83 as well as another series: TI85/86) are all driven by a Z80 processor architecture.

Hello Marcus, Thank you for the info. Duly noted. I can understand where HP got the ideas for the 49/50 design without the big ENTER key. Fortunaltely the 89 can run on RPN. And I thought the 50G's menu system was annoying... At least you can change it to the 48 series' style.
