Oric-1 - created by Tangerine Tangerine had been around for a few years, and had previously been selling a 6502-based one-board computer called the Microtan. This was abandoned after around 10,000 systems had been sold, but was rescued by Microtanic computers in 1983[source: "Back from the brink", Personal Computer News, September 1 1983, p. 26]. Meanwhile, Tangerine's technical director Paul Johnson founded Oric Products International in St. Ives - the original home of Sinclair Radionics - in order to develop the Oric, but this advert clearly shows the transition before this happened, when the Oric-1 is advertised as made by Tangerine. See also Oric.
