This model is notable for very early use of an LCD display. Too early one might say, all 3 of the units in my possession utilising these displays have only partially operable displays, bubbles having developed in the liquid crystal.

The same electronics as the Lloyd's Accumatic 70 but packaged in a different case. See the Lloyd's 70 for the schematic.
