Oric was the name used by Tangerine Computer Systems for a series of home computers, including the original Oric-1, its successor the Oric Atmos and the later Oric Stratos/IQ164 and Oric Telestrat models (model names stylized in upper case).
A Yugoslavian company obtained a licence to make just 5,000 machines. Machines were made, but whether they were under license or not is not known in any detail. They were Atmos based, the only difference being the logo indicating ORIC NOVA 64 instead of Oric Atmos 48K. Nova had 64 KB of RAM, 16 KB of which was masked by the ROM at startup, leaving 48 KB to work with the BASIC language.
With the success of the Sinclair ZX Spectrum, Tangerine's backers had suggested a home computer and Tangerine formed Oric Products International Ltd to develop and release the Oric-1 in 1983. Further computers in the Oric range were released through to 1987 with Eastern European clones being produced into the 1990s.
Oric emulates an Oric 1 and an Oric Atmos. It supports full cycle exact sound, allowing speech effects such as that in Megademo to work perfectly, and almost perfect compatibility with a real Oric. You can download it from Richard Banniste' site.
Oricutron is a multi platform Oric emulator that is still WIP but usable. You can find OS X port at Peter Gordon's download page.
