Calculator in its sleeve with holder for a
checkbook, credit cards and pen. |

| This
Olivetti DII Checkbook Calculator
was
manufactured in June 1990 in Thailand.

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