This calculator is just a slight modification of the earlier LC-833WA. Please notice the separate RM and CM keys on the LC-833WA and its copies.

A perfect copy of this calculator was sold in the former GDR (German Democratic Republic - Eastern part of Germany) as MR411 and later MR413.

The battery holder is a typical Toshiba design, you'll notice it in some other calculators sold as OEM products, e.g. some yellow-LCD Radio Shack calculators. Don't miss the EC-264

With the later LC-853WA, LC-854WA and LC-859WA much smaller combinations of a basic calculator and a clock with alarm and calendar appeared.
