This Corvus
Model 625 combines the housing of the scientific Corvus 500
calculator with the functionality of the Corvus 615.
While the Corvus 615 sports a vacuum fluorescent display (VFD) manufactured by
Itron, uses this Corvus 625 a light emitting diode (LED) display from Hewlett
Packard.
Fellow collectors: We noticed
Corvus 615 calculators with both VFD and LED displays and even a Corvus 625 with
a green VFD was recently reported. If you own either a Corvus 615 or 625
calculator, please drop us a line with its serial number and display technology.
Thanks!
Other calculators sold under the Corvus brand are the
310, 320,
400,
and 415 models. Don't miss the colorful
Corvus 804.
