Corvus, the consumer division of the famous IC manufacturer MOSTEK, introduced with the Model 322 a basic four-function calculator with full memory.
printed circuit board (PCB) of the Corvus 322 makes use of the MK5022A
single-chip calculator circuit. We know the MK5020A,
a clone of the Texas Instruments one-chip calculator circuit TMS0102.
But this one lacked the memory. Learn more about Mostek
Calculator Integrated Circuits.
Three different models were available:
Model 320: Includes four AA-sized batteries.
The Corvus 310 series removed the memory but added the square-root function. 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.
