What it does:
It ONLY allows you to key in the keycodes of programs from the hp97 into a TI58C or TI59.
The module will run a long long time and then spit out a print out (printer is required) of a translated TI program that performs equivalently to the original RPN program.
This program then must be re-keyed into the TI calculator from scratch to be run.
What it does not do:
It does NOT allow you to use the TI calculator in an RPN operational mode.
It does not support all HP97 features. It won't do rapid reverse branching for example. I think it also has problems (if I'm remembering correctly) with P<>S (primary to secondary) memory switches.
All in all, although I have had this module for years now, I have never once used it. I really can't imagine an HP97 program that was so compelling that I'd want to try to run it on a TI58C or TI59. I think I'd just run it on the original hp97.
Here's what I said about the module several years ago (which can be found on my old HP and TI website: http://www.rskey.org/gene/calcgene/59mods.htm)
"Module #13, RPN Simulator. Although I have one, I have never used it. This module was a very strange one for TI to make. Apparently, they were getting tired of people claiming HP's were better calculators so TI decided to make this module as its answer to HP and RPN. (Or they may have realized that there was a lot of software programs out there for HP's and wanted to give their users access to it). It's an entire module with one executable program on it. You run the program and key in HP-97 program KEY CODES. You could take a printed program listing for the HP-97 (this would NOT work for HP-67 key codes, only the HP-97) and key in the program steps keycode by keycode. When finished, the program would go off and compute and eventually (and this took a while) print out a TI-59 equivalent program. This then had to be KEYED back into the TI-59 to run. The usefulness of this module is somewhat suspect. First, only keycodes from a HP-97 listing can be used. Second, not all instructions from the HP-97 can be interpreted or emulated by this module. The manual (woefully concise) provides a list of these functions. Also, the resulting program often doesn't run very well at all speedwise. TI did give a very good effort, however. Their timing was terrible, as this module came out only a few months before HP introduced their HP-41. This module did NOT work except to translate programs."
