Sharp Electronics Corporation introduced May 15, 1973 with the EL-805 the first calculator using a LCD display.
This EL-808 used the same type of Sharp's unique silver-coloured COS-LCD display in a desktop style calculator. These early COS-LCD's needed always a flap above the display to protect it against ambient light.
simple but robust construction of the EL-808 traces back to the EL-811
and EL-8102 calculators introduced in 1971 resp.
Compared with the above mentioned calculators the electronics was greatly reduced and fitted on a small part of the printed circuit board (PCB). The remaining place is occupied by the keyboard.
