Oric-1 - created by Tangerine

Tangerine had been around since 1978, and had previously been selling a [!6502]-based one-board computer called the Microtan 65. 

This was abandoned after around 10,000 systems had been sold, but was ressurected by [@Microtanic|Microtanic Computer Systems] in 1983[source: "Back from the brink", Personal Computer News, September 1 1983, p. 26]. 

Instead, the company switched its focus to the market created by Sinclair's [#ZX Spectrum], and designed a small, games-oriented machine suitable for use in the home, called the Oric-1.

With funding from British Car Auctions, Tangerine created a separate company - Oric Products International - in order to manufacture and promote the new machine. 

The new company was based in St. Ives - the original home of Clive Sinclair's Radionics company, but the transition had not happened yet, as this advert shows the Oric as still very much a Tangerine machine.
