This is Factory sealed, unopened, with the original batteries in the box. This TI-92 is NOT the "Plus" model. (This makes it even more rare) The history of this calculator is that it was a fluke product released by Texas Instruments that was supposed to cater to the educational market, but this model of calculator was BANNED from most standardized testing, as the full keyboard considered more as a "pocket-sized computer" than a "calculator." This is one of a kind, and the ONLY ONE listed on eBay. Will be gone fast!
