The Colour Genie was powered by a Z80A microprocessor running at a clock speed of 2.2 MHz. It came standard with 16 KB of RAM, which could be expanded to 32 KB, a substantial amount for a home computer at that time. In terms of graphical display, the EACA EG 2000 supported a resolution of 96x160 pixels with the ability to display 4 colors, providing vibrant visuals for games and software. A later version, identifiable by the meter indicating the level of cassette signal input to the computer, increased this resolution to 102x160.

The Colour Genie used Colour BASIC. Aside from commands for color, graphics, and sound, this BASIC was compatible with that of Tandy's TRS-80 Model III. After booting the computer, about 26 KB was available for BASIC programs in the 32 KB configuration.

For storage, the Colour Genie used cassette recorders, a common solution in the early '80s before floppy disks became standard in the home computer market. Users could optionally choose floppy disk drives to improve their data storage capacity and access times. BASIC was used as the operating system, a popular choice for many personal computers of that era because of its accessibility to both beginners and more experienced programmers.

Although the Colour Genie was mainly sold in Europe, particularly in Germany, the device enjoyed some popularity due to its affordability and relatively strong performance. This was facilitated through a partnership with the German distributor, Trommeschläger. Despite its advantages, the Colour Genie was eventually overshadowed by competing systems like the Commodore 64 and the Sinclair ZX Spectrum, which offered comparable price-performance ratios and attracted a larger user base.
