Sharp EL-506W
Brief History
The Sharp’s Advanced DAL Series which was introduced in 1996, has the EL-506L (EL-556L) member with two line display, which allow to correct or rewrite the entire entered formula at any time, even after performing a calculation (Playback function). In 1999, with the introducing the new R-series, the EL-556 was discontinued, and replaced by the EL-546R, which, like the previous 546s, had solar cells and many other functions: calculating integrals and with stored user-defined formulas. The EL-506R was identical to the EL-546R. In 2002, this type was replaced by the new V-series models (EL-506V, EL-546V) in a new color and form, but with the same knowledge.
In 2005, the EL-506W (EL-546W) was introduced as a member of the W series. New features in the W series include advanced menu functions and extended 14 + 2-digit internal capacity.
