Sinclair Oxford

Sinclair Oxford was a range of low-cost scientific calculators manufactured and sold by Sinclair Radionics in England, United Kingdom from 1975 until 1976. The first model was the "Oxford 100", launched in Spring 1975 for UK£12.95; this model was based on the "Gillette GPA" from late 1974 that was made by Sinclair for Gillette in a slightly different case. Both the Gillette GPA and Oxford 100 models used 8 digit displays with red light-emitting diodes (LEDs), 4 functions, 9volt PP3 batteries. Both models measured 73 x 155 x 34 mm (2.9 x 6.1 x 1.3 inches).

All the Oxford models were similar in appearance; the 150 was introduced in 1975 introducing the ability to calculate percentages and square roots. The "Oxford 200" included memory and sold for £19.95. The "Oxford 300" was a scientific model with a limited number of functions (such as sin, cos, tan), which sold for £29.95, much lower than the competition. The last two models, the "Oxford Scientific" (1976) and "Oxford Universal" were the most advanced of the range.
