Need help with my TI-89.

[Imported]

Is it worth it to upgrade to v2.05 from v1.05? If I did, is there a way to save the v1.05 to my PC so I can put it in later if v2.05 doesn't work? I've dumped the rom from it using Virtual Ti, but I'm not sure how it'd help if I need to put back v1.05 again. Any input would be appreciated.

Get 2.03 at all costs. Most of the ASM community doesn't support 1.xx since it doesn't support Hardware2 calcs, and 2.04/2.05 screws up most ASM programs.

Where could I find v2.03? I can't find it on Ti's site anywhere.

Unfortunately, I think you'll have to email TI about it, I don't have a clue to the location of my copy.

Okay, thanks. I'm just about to e-mail them about it now. Thanks for the help.
