Unfortunately, this poor TI-55 has had a hard life. When I first got it, the trim had mostly worn off and even changed color in multiple places. I repainted the trim with my best reference to the original paint that TI used. However, the original TI rechargable pack appears to have leaked and ruined the display. This unit is irreparable, at least with my skills. This model was originally released in 1977, though mine appears to have a 1980 date code.
