The TI-Graph Link program for the TI-86 on the Macintosh is somewhat different than earlier TI-Graph Link programs. The Quickstart Help in the program is quite useful.
Begin by opening a TI-86 connection as follows. Connect the TI-86 to the Macintosh using the Graph Link cable and turn the TI-86 on. Under the Connection menu choose the option TI-86. It may be the only option. Make sure the correct port is selected (the other options are standard) and click OK. A new finder window should appear showing the contents of the TI-86.
You can move files to the TI-86 by dragging them from a Macintosh window to the TI-86 finder window. To move a program that has just been downloaded from the Web to the TI-86, first store it someplace convenient and then drag it to the TI-86 window.
The Help menu in the TI-86 provides access to useful help.
Connect the TI-86 to the Windows computer using the Graph Link cable and turn the TI-86 on. If you have just downloaded a TI-86 from the Web, store it someplace convenient on your computer.
Choose Send under the Link menu. Find and double click the program that you want to send to the TI-86 by browsing in the usual way. It should appear in the File Selected box. Then click the OK button.
