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.
