Changes
The Oric-1 and Oric Atmos were [[6502]]-powered competitors to the 48kb [[ZX Spectrum]]. The Oric 1 has very much the same form factor, including calculator-style keys, but the Oric Atmos provides a full-travel keyboard.
Originally one of the competitors for the contract to be the [[BBC computer Micro]] that was ultimately awarded to [[Acorn]], the Oric retains an unusual mixed text/graphics display mode that utilises inline colour attributes.
The Oric's display is 40 bytes across. Each of those bytes may be a control code (to change foreground or background colour, enable or disable graphics mode, etc) or actual content. While in text mode, the content is a character code and the character graphic is looked up indirectly. While in graphics mode, the content is a direct representation of the pixels on that line.
