Later Hand-held LCD Calculator Photograph Library

This page has links to photographs of apparently later LCD (Liquid Crystal Display) pocket calculators, that is those with the later type of LCD display with black digits on a grey background, probably manufactured in the late 1970s and 1980s.  Although the rate of technical development of calculators had slowed down by this time it is still interesting to compare the different models available then.

LCD displays are explained further in the Calculator Displays section.
