Online Calculator

To download a TI-83 Plus Flash Debugger (virtual calculator) from Texas Instruments Incorporated:

Go to TI Download Page.

Scroll down to select “TI-83 Plus SDK” from the Download Item table.

After signing in or continuing as a guest, save the file “83psdk_setup.exe” to your desktop.

Click the “83psdk_setup.exe” icon on your desktop and follow the on-screen installation instructions.

After installing, follow the prompt to restart your computer.

Click the “TI-83 Plus Flash Debugger” icon on your desktop.

Select File > New and choose your calculator type. Then click OK.

Select Debug > Go. A virtual calculator should appear; you may now minimize the Debugger window. (I had to click an > key, the forth button from the left to view the calculator.)

Repeat steps 6-8 anytime you wish to open the virtual calculator.
