Checkbook Calculator in its
sleeve with holder for a checkbook and pen.
Radio Shack EC-430 Checkbook Calculator was
manufactured in August 1992 in Thailand
(Date code 8A2 » mth 08 yr 1992).

(PCB) of the EC-430 manufactured in 1992
doesn't reveal type and manufacturer of its
single-chip calculator circuit but we are almost positive to spot a Toshiba T7752S.
