Toshiba introduced in 1978 with the BC-8112SR a Basic calculator adding the Square Root function to the otherwise very similar BC-8018B and BC-8111B calculators. While the original designs of the BC-8018 and BC-8111 were based on single-chip calculator circuits from NEC, is the BC-8112SR centered around a TMS1045 chip based on the TMS1000 Microcomputer family

Early in 1979 Toshiba's contract manufacturer Zeny Corporation in Taiwan consolidated the internal design of the BC-8018B (Version 2), BC-8111B this BC-8112SR but renamed it to BC-8112SL.
