Acquired as part of a lot of 18 calculators on July 8, 2022. According to the date code this calculator was manufactured in the 49th week of 1976 in the USA at the Lubbock, TX plant. I have confirmed that it is functional using a 9v battery, however, the original battery pack is no longer functional and will either need to be refurbished or replaced with a modern battery solution.
