An optional TI-92 E module is provided in a box.
The + key doesn't work (then the `diamond + plus` keystroke can't be used to increase contrast).
When I received the calculator, pressing a key dimmed the screen for the time the key was pressed and sometime the calculator was shutting down itself when pressing keys. The calculator was not stable on Alkaline or Ni-Mh batteries, it was only stable on Li-Ion ones. I cleaned up some trace of old battery leakage on the motherboard and now the calculator is stable. It would be in “Good” condition if the `+` key was working.
