I\'m selling these two calculators with only one cord...you get everything you see in the picture...I tried the SR-16 connected with aa batteries and it worked...I opened the battery pack to the SR-50A and it looks old. I connected it but only gives me flashing numbers. Don\'t know much about calculators. Wouldn\'t know where to get a new battery pack for the SR-50A so not sure how it works. It comes with the manual and box and 2 cases as seen in the picture...please let me know if you have any questions...
