Gemini

The manufacturer of Gemini calculators is a little puzzling. Some of the calculators are marked as made by Newlyn Electronics, Voundervour Lane, Penzance, Corwall and others by Emihus Microcomponents Limited.

Newlyn Electronics manufactured control equipment, and in the mid-1970s it also produced several models of Gemini calculator, before going into liquidation in 1976.

Emihus Microcomponents Ltd. was jointly owned by EMI (Electrical and Musical Industries) of the UK and Hughes Aircraft of the U.S.A., and based at Clive House, 12-18 Queen's Road, Weybridge, Surrey. Emihus was a manufacturer of LSI (Large-Scale Integration) calculator integrated circuits, and was reported as having launched the Gemini range of calculators as well as having manufactured an early Hanimex calculator model, the Hanimex BC808 which is shown at the bottom of this page for comparison.

It may be that Newlyn Electronics was a sub-contractor of Emihus and also a distributor of the calculators.
