This is a version of the Sharp EL-801 made for Dixons, with a slighly cheaper plastic body.
This was the first calculator to use CMOS (Complementary Metal-Oxide Silicon) integrated circuits, which have very low power consumption (though here negated somewhat by the use of the relatively high-current LED display).
The display board, upper-left, plugs into the processing board, lower-left. The assembly is then turned over and plugged into the back of the keyboard, on the right.
The integrated circuits are on the processing board.
