This Toshiba BC-815 was introduced together with the BC-8012 and added a 3-key memory to the basic functions of its sibling. 

Dismantling this BC-815 reveals indeed a printed circuit board named "BC-8012" and sporting a Toshiba T3189 singe-chip calculator circuit. The BC-815 was replaced in 1977 with the BC-8111 in a slightly smaller package sporting a NEC uPD1803C chip.

An identical calculator was sold as Model OKU201 by Tesla of Bratislava in the Czech Republic. (Karel Polák, Thanks for the information!)
