Description

Brand:	CASIO
Model:	MINI CM-604
Type:	Calculator
Picture:
Batteries:	AA x 4
Lifetime:	Introduced: 1974 Terminated: unknown
Notes:	Early CASIO model, quite a nice horizontal design. The fluorescent display shows only 6 characters, the remainder of the result can be viewed by pressing the ► key and holding it. The display has a peculiarity, the zero is lower case! I don’t know any other calculator series apart from the early CASIO’s that have a lower case zero. Shown here is how the number "204.080" is displayed on this calculator. The calculator runs on batteries as well as on a power adapter.
