The Corvus 600 is the rare financial sibbling of the scientific Corvus 500 calculator. Both use the same hardware architecture based on the MK50075A Data-Processor with just a different programmed ROM-set: MK50101/2 for this financial calculator and MK50103/4 for scientific calculators.

Dismantling this Corvus 600 calculator manufactured in October 1975 reveals a different PCB (printed circuit board) than the Corvus 500 replacing one display driver IC with discrete transistors.
