The Conti 20 was introduced in 1976 together with the Conti 10 and could easily be identified as a far-east OEM-product manufactured by Toshiba.

Conti-20_PCB.jpg (46308 Byte)The printed circuit board (PCB) of the Conti 20 looks familiar and is centered around a Toshiba T3393 single-chip calculator circuit. We know this chip already from the Toshiba BC-819 and BC-8110 calculators.
