Purchased at a Value Village thrift store on October 15, 2022. According to the date code this calculator was manufactured in the 49th week of 1981 in the USA at the Abilene, TX plant. For whatever reason the actual model name for this calculator (TI-1890) is not stated anywhere on the device. Currently not in working condition.
