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
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.
