box of the Royal CBC 80NT Checkbook Calculator sold around 1987
in the US. |

This Royal CBC 80NT Checkbook Calculator was manufactured in 1987 in Taiwan. | |
The printed circuit board
(PCB) of the Royal CBC 80NT manufactured in 1987
doesn't reveal type and manufacturer of its single-chip calculator circuit but we are almost positive to spot a Toshiba T7752S.
