Description Notes

TI-85 Scientific Calculator, Texas Instruments, American, 1992-1997.

A scientific calculator made between 1992-7 by Texas Instruments in Dallas, Texas, United States. This specific model is the TI-85 and is accompanied with a model-specific manual book. The calculator features a larger-than-normal display to output graphical illustrations, and both the chassis and sleeve are black. The reverse face of the calculator features a manufacturing inscription with a copyright mark dated 1991 as well as various serial numbers. This object is complete, and the battery compartment has been damaged due to old batteries leaking battery acid in the surrounding area and the inside-face of the battery cover. The manual remains in very good condition with minor creases. This object consists of four parts: calculator, sleeve, battery cover, and model manual book.
