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.
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.
