==Links== Notes program: TI Connect CE: Video for TI 84 Plus C Silver Edition: IMPORTANT: Error: Invalid means you have a newer operating system that disables the ability to run this program. To fix this, you will need to jailbreak your calculator: Once you have jailbroken your calculator, run the TFILES program inside of the CalcPlex app (not NOTES). Questions? Just Ask!!! Andres Sevilla
