This Toshiba BC-8012 is almost identical with the BC-815 but misses the 3-key memory in the upper row of the keyboard. 

BC-8012_PCB.jpg (57934 Byte)Dismantling the BC-8012 reveals the Toshiba T3189 single-chip calculator circuit introduced already in 1973. The BC-8012 was replaced in 1977 with the BC-8018 in a slightly smaller package sporting a NEC uPD1802C chip.

The later BC-8013 combined the same functionality into a much smaller housing. Overall weigh was reduced from 6.5 ounces to only 4.8 ounces.
