Ive got 2 TI84+'s running 2.43. One is fine but the OS acts up sometimes. It seems mine has some unique problems every once in a great while.
My other one is fine but i inherited it from a friend who lost the both the slide case and the battery cover, and he burned a hole in the screen by leaving it running too long (something like 2 days).
Is this "hole", a hole? Or is it something that looks like a ink-spot?Because we do havve something like that on our Ti-92+
