The Royal/Olivetti CBC 80 Checkbook Calculator in its sleeve with holder for a checkbook, credit cards and pen.

This Royal/Olivetti CBC 80 Checkbook Calculator was manufactured in 1990 in Thailand.

The printed circuit board (PCB) of the Royal/Olivetti CBC 80 manufactured in 1990 doesn't reveal type and manufacturer of its
single-chip calculator circuit but we are almost positive to spot a Toshiba T7752S.
