Corvus, the consumer division of the famous IC manufacturer MOSTEK, introduced with the Model 415 a basic four-function calculator with full memory, 1/x, and percent keys. Main difference to the Corvus 310 and Corvus 320 is the added 6th row of keys we know already from the Corvus 411.

Corvus_415_PCB.jpg (98976 Byte)The printed circuit board (PCB) of the Corvus 415 makes use of the MK50203N single-chip calculator circuit. We know this chip already from the Corvus 307, a late desktop calculator. Learn more about Mostek Calculator Integrated Circuits.

The Corvus 400 uses in contrast to these models a different housing. Other calculators sold under the Corvus brand are the 500 and 615 models.

Don't miss the Magiclick 450, a perfect doublet of the Corvus calculator using a brain manufactured by Rockwell.
