Additional Pictures 

 

This Sears LC89 was manufactured in Japan in March 1981.

The printed circuit board (PCB) of the Sears LC89 looks very familiar
to us. It is identical with a PCB located in a Toshiba SLC8260.

Even the single-chip calculator circuit with the unusual part number
PN1033724-1 is known from the Toshiba SLC-8260.
