Featured Portable Electronic Calculators:

For a short period in the early 1970s several models of electronic calculators were produced that were hybrids and contained both a transformer for working from an AC supply and also batteries so that they could be used away from the AC.  These calculators are too large and heavy to be called hand-held calculators and so are featured here as portable calculators.

Very rapidly, developments in electronics drastically reduced the number of components in calculators, together with the power consumption, and caused a reduction in size and weight and so allowed small hand-held calculators to be produced, as illustrated in the Featured Hand-held Calculators section.

For information about the electronics inside the calculators see the Calculator Technology section.
