We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

Oric 1 48k

Oric was a British designed and built machine. Oric-1 was released in 1983. Based on a 1 MHz  6502A CPU, it came in 16 KB or 48 KB RAM variants for £129 and £169 respectively, matching the models available for the popular ZX Spectrum and undercutting the price of the 48K Spectrum by a few pounds. Both Oric-1 versions had a 16 KB 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 and the later Oric Stratos/IQ164 and Oric Telestrat models. To keep their Oric and Microtan brands separate, they formed a subsidiary company Oric international.
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.

The Oric-1 improved somewhat over the Spectrum with a chiclet keyboard design replacing 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 color 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.


According to Oric about 160,000 Oric-1s were sold in the UK in 1983 with another 50,000 sold in France (where it was the top-selling machine that year).
