I've spent the last two days of class time experimenting with the TI-82, 83, 85, and 92 graph links. Here is my principal observation:
The TI-83 can read (or convert) all the other TI's data list. However, the TI-82 and TI-85 will not read (convert) a TI-83's list.
If you have observed otherwise or you know how to "easliy" convert TI-83 list into a form that the TI-82s and 85s can read, I would greatly appreciate hearing from you. Otherwise, until I get a class set of TI-83's it appears as though I'll have to be making at least two data sets of everything.
