content: According to records of Canadian trademarks, in 1982 Kmart Canada began using the trademark KMC for calculators and other devices sold in its stores. The trademark was registered in 1984 and discontinued in 1999. The KMC mark on the calculator indicates that the trademark is registered. No such trademark, as applied to calculators, is included in the U.S. registry of trademarks. The calculator came to the museum in 1986, hence it appears that this calculator was distributed by Kmart Canada and made in around 1985.
