Does anyone know how to make a TI-92 USB cable or know where to get one for cheap? I want one to update the firmware on my TI-92.  :)

You will have to buy a Silverlink USB cable from Texas Instruments, preferably on Ebay or something if it's cheaper there.

You cannot upgrade your TI-92, though, unless you got the very rare Plus module attached to your calculator, which basically turns your TI-92 into an hardware revision 1 of the upgradeable TI-92 Plus. All you can do is transfer TI-92 files.

How do I know if I have the Plus module attached to my calculator?

You need to open the back of the calculator as if you wanted to, say, change the batteries, which requires moving a piece of plastic on the top (or bottom ?) side to unlock the back. You might then see one of the modules listed at e.g. http://www.datamath.org/Graphing/TI-92_Expansion.htm .

One of the software ways to check whether you have a Plus module should be the availability of "Archive" / "Unarchive" entries in Home -> 2nd -> Var-Link -> F1. If they're missing, then the calculator doesn't seem to provide user-accessible Flash memory.
