Connectivity Kit - The capabilities of TI-8X series calculators are greatly enhanced if you have a connectivity kit. This allows you to connect your calculator to your PC or Mac. That, in turn, allows you to transfer information between the devices, so you can download data to the TI and upload graphs from the TI to your computer. Connectivity kits are available at TI retailers and through the TI calculator website. They cost about $20. Be sure to get one compatible with your calculator.
