Ti 36 Appraisal

Texas Instruments TI-36X Pro Scientific Calculator

The item is a Texas Instruments TI-36X Pro scientific calculator, characterized by its black plastic casing and a standard QWERTY-like layout for mathematical functions and numerical input. Its dimensions appear to be consistent with a handheld device, designed for easy portability and single-handed operation, as evidenced by a hand holding it in the image. The calculator features two distinct display screens: a smaller, upper display likely for status indicators or basic output, and a larger, lower LCD display for primary input and results. Both screens are currently unlit or off, appearing as translucent green-grey panels. The Texas Instruments logo is clearly visible below the smaller upper display, while 'TI-36X Pro' is printed prominently at the top. The keys are primarily grey and black, with white lettering for primary functions and blue or light grey lettering for '2nd' functions, indicating a multi-layer functionality. Notable sections include a numerical keypad (0-9) and dedicated buttons for trigonometric functions (sin, cos, tan), complex numbers, statistical operations, and various algebraic features. The construction appears sturdy, typical of scientific calculators designed for student and professional use. There are no overt signs of significant damage such as cracks or deep scratches; however, some minor wear or dust might be present on the surface, consistent with regular use. The overall condition suggests a well-maintained, functional device. The calculator is modern in style and likely belongs to the late 2000s or 2010s production era.
