Tip of the day:
In addition to the familiar TI Connect software – used to transfer TI89 apps from a computer to a TI89 – there now exists TI Connect CE software that only works for TI84 calculators.
So if you mistakenly try to transfer ti89 apps using the CE version you will run into transfer errors and don’t know why.
To avoid these transfer errors make sure to download the TI Connect software for TI89s at http://ti89.com/ticonnect.php or at education.ti.com .
