We don't know too much about this calculator, it looks very unusual with the white housing and doesn't match with the LE-80 and LE-82 design.

The internal electronics is based on two calculator chips manufactured by Toshiba. With the LE-81M the TI brain was back in Canon's LE-calculator line.

Another "TI-less" product was the scientific calculator F-5 sporting a Rockwell brain.
