Remember the awesome TI-85 Calculator

I never had the heart to let mine go. I am going to start tutoring algebra II next week and I was all excited use my old trusty awesome calculator. Unfortunately, the graph button does not work anymore. I broke it open, cleaned all the contacts with electrical cleaner and still nothing
