Conti-10_PCB.jpg (53248 Byte)The printed circuit board (PCB) of the Conti 10 looks familiar and is centered around a Toshiba T3332 single-chip calculator circuit. We know this PCB already from the Homeland 8006 and the Toshiba BC-8016. The former calculator used even an identical housing, the latter looks slightly different.

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