Colour Genie

The EACA EG2000 Colour Genie was a computer produced by Hong Kong-based manufacturer EACA and introduced in Germany in August 1982. It followed their earlier Video Genie I and II computers and was released around the same time as the business-oriented Video Genie III.

The BASIC was compatible with the Video Genie I and II and the TRS-80, except for graphic and sound commands; some routines for Video Genie I BASIC commands were left over in the Colour Genie's BASIC ROM. Programs were provided to load TRS-80 programs into the Colour Genie. Colour Genie disks could be read in a TRS-80 floppy disk drive but not vice versa.

The original Video Genies had been based upon (and broadly compatible with) the then-current TRS-80 Model I. As the Colour Genie was descended from this architecture, it was incompatible with Tandy's newer TRS-80 Color Computer which - despite its name - was an entirely new and unrelated design based on an entirely different CPU, and thus incompatible with the TRS-80 Model I and derivatives such as the Color Genie.
