I just bought a used TI-89 original calculator on ebay. I looked and it has OS 1.00. I tried sending a game to the calculator using the USB silver link cable. It says there was an error. When it scans for a calculator, it does find it, and I am able to take screen shots with it, but I cannot upload games. I read that it might not work on the older OS. I am trying to find an OS ROM update for it but I can't find it anywhere and TI no longer has a download for it. Please help.

DÃ©dÃ©!

Sigh of relief... works!

I accidentally made my calculator a paper weight when the first upload attempt failed.

Tried it again, and it works great .. and new OS!

Now I can upload programs to my calc!
