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.
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.
MBO
International Electronic GmbH, Jena was founded 1973 and started with the MBO
Junior the production of the first portable calculator in Germany.
