Texas Instruments 58C (NO BATTERY) calculator Library 1980 USA

From TI / Texas Instruments, the maker of high tech programmable calculator (and a lot of other high grade stuff) comes this 1979 introduced calculator model 58C, a scientific programmable calculator with loads of functions. It came with the additional Library 1 in a folder, including cards and empty cards as well as an overlay. All accounted fore (2 empty slots where empty cards may have been). It is clean but I was not able to test it because it came without the original battery pack. so this one comes untested with NO BATTERY included and priced accordingly. It does have the library and the original leather case that houses all. Selling as a cool desk display piece.
