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 MS5020A single-chip calculator circuit. We know since we dismantled a Heathkit IC-2006 the MK5020A, a clone of the Texas Instruments one-chip calculator circuit TMS0102. But these two lack the square-root key...
Three different models were available:

	Model 310: Includes four AA-sized batteries.
	Model 311: Includes four AA-sized batteries and an AC adaptor for 115V.
	Model 312: Includes rechargable NiCd-batteries and an AC charger for 115V.

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 Magiclick 450, a perfect doublette of the Corvus calculator using a brain manufactured by Rockwell.
