Radofin & Triton

Radofin Electronic was based in King Street, West London and marketed a variety of advanced consumer electronics.

In July 1974 there was a report of three newly formed electronics companies, Radofin Electronics of London, Radofin Electronics of Liechenstein, and Radofin Electronics (Far East) of Hong Kong[1]. Later Radofin models were manufactured in Hong Kong.

By January 1978 Radofin Electronics (Far East) were leaders in the electronic games business. It had once led the market in calculators, its only product until September 1976, but had seen the end of the calculator boom and moved into games production[2].

Triton was a registered trademark of the company and the earlier calculators bear the Triton name, whereas later calculators carry the Radofin name.

Some early Triton calculators were manufactured by Advanced Telecommunications Equipment (ATE), of Woking, Surrey, and resemble that compny's Taktile models. ATE was a small manufacturer of telecommunications and other equipment, and marketed its own Calate range of electronic calculators for about 18 months. It ceased this at the beginning of 1974 to concentrate on OEM production for other companies, including Acme Electric (Ajax) and Radofin (Triton), with trade enquiries being handled by Radofin Electronic[3]. The company manufactured its own membrane tactile keyboards.

This is fairly thin calculator with a "pregnant" bulge to accomodate the 9v battery. Unlike some Sinclair models which had the same feature, the bulge here is at the top of the rear so the calculator sits on a desktop at a usful angle inclined to the user.
