The Oric-1 was a British-designed and built machine, which was released in 1983. The computer was based on a 1 MHz 6502A CPU. The Oric-1 was available in 16K or 48K RAM variants, initially for £129.95 and £169.95 respectively, matching the available models of the popular ZX Spectrum and undercutting the price of the 48K Spectrum by a few pounds. Both Oric-1 versions had a 16K ROM containing the operating system and a modified BASIC interpreter.
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, the later unreleased Oric Stratos/IQ164 and the model born out of that, the Oric Telestrat.
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. The Oric is said to be named after the computer, Orac, in the BBC science-fiction series Blake's Seven, according to the December 1982 edition of Practical Computing.
The Oric-1 improved somewhat over the Spectrum with a solid chiclet keyboard design an improvment over the Spectrum's renowned "dead flesh" one. In addition the Oric had a true sound chip, the programmable GI 8912, and two graphical modes handled by a semi-custom ASIC (ULA) which also managed the interface between the processor and memory.
The two modes were a LORES text only mode (though the character set could be redefined to produce graphics) with 28 rows of 40 characters and a HIRES mode with 200 rows of 240 pixels above three lines of text.
Like the Spectrum, the Oric-1 suffered from attribute clash—albeit to a lesser degree in HIRES mode, when a single row of pixels could be coloured differently from the one below in contrast to the Spectrum, which applied foreground and background colour in 8 x 8 pixel blocks.
As it was meant for the home market, it had a built in television RF modulator as well as RGB output and was meant to work with a basic audio tape recorder to save and load data.
