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.
