Toshiba BC-8112SL uses the TMS1045 calculator chip based on the TMS1000
Microcomputer family. In opposite to the very similar TMS1043 found in the
Texas Instruments TI-2550-III,
the TMS1045 was available to other companies.
Main advantage of the TMS104x circuits are the integrated drivers for green flourescent displays to minimize manufacturing costs of the calculator. Due to the simple design of the hosting calculators, the TMS1045 found its way into differerent brands. Not all used the whole functions of the circuit:
The Toshiba BC-8112SR seems to be identical with the BC-8112SL.
The design of the BC-8111B with its black, blue and red keys traces back to the BC-819 introduced already in 1976.
