TI-84 Plus Silver Edition Calculator

Selling As-Is. This is a Texas Instruments TI 84 graphing calculator. Please refer to the pics... Found this at an estate sale. Missing the manual, did find an online copy. No box. The calculator powers on and all appears to be functioning. there is a 357 backup battery that I removed. It was flat. The calculator is in good shape, there are pencil marks in the recessed areas of the case around the battery door ....etc. Battery box has no corrosion, the data ports appear good, but I cannot test. The screen is clear and shows no damage. Comes including the slide off cover. Thanx for looking...
