How to Open Finance App CellSheet, etc. on the TI-

The first 2 builds of the TI-89 are not the Titanium. The additional apps you load, such as cell sheet, finance, etc. must be loaded via the Flash Apps. So you press APPS then FlashApps then Select the App you want to load

How did you get the finance app on there to begin with? Mine is not loaded

I know this is too late for you. But for someone else reading, if you have a ti89 (not titanium) you need the connection cable between the calc and USB, and then you have to download a transfer program from TI. You then download the finance app from TI, and use the transfer program to get the app added to your calculator.
