Corvus,
the consumer division of the famous IC manufacturer MOSTEK, introduced with the
Model 310 a basic four-function calculator with added square-root and percent
keys.
The
printed circuit board (PCB) of the Corvus 310 makes use of the MK5020A
single-chip calculator circuit. We know the MK5020A,
a clone of the Texas Instruments one-chip calculator circuit TMS0102.

Three different models were available: •
Model 310: Includes four AA-sized batteries. |
The Corvus 320 series removed the square-root function but added a full memory. Other calculators sold under the Corvus brand are the 400, 415, 500, and 615 models. Don't miss the colorful Corvus 804.
Don't miss the Magiclick 450, a perfect doublet of the
Corvus calculator using a brain manufactured by Rockwell.
