Purchased on kijiji on January 4, 2021. According to the date code this calculator was manufactured in February of 1999 by Inventec in Taiwan. This TI-83 uses the same internals as a standard TI-83, but uses the updated TI-83 plus case since it is the 1999 revision. Currently in working condition with occasional vertical lines on the screen.
