The Colour Genie was the successor of the Genie 1, Genie 2 and Genie 3. It was intended to compete with the Tandy Color Computer although it was not at all compatible with its model (Z80 microprocessor instead of a Motorola 6809 in the CoCo)
The graphic resolution wasn't as good as the CoCo, furthermore it was not possible to mix characters and graphics.
However, the machine was reliable and solidly built. It featured a good mechanical keyboard and even a little level display located above the keyboard, which allowed to set the recording level of the tape recorder to improve reliability when writing onto a tape.

I used to own the colour genie back in the 80''s and had a 16K RAM extension. I lost my original genie long ago but recently I acquired (ebay) one (no RAM extension). I am looking to get extension or build one. If any one can help with technical information it will be great. Note that I do have the Colour_Genie_Technical_Manual_1984_Lowe_Electronics File but the information do not have complete electric diagram.

It was the colour version of the VideoGenie/System 80 which were compatible with the TRS-80. It was never intended to compete with the CoCo, which wasn''t very successful anyway.

This was the first computer I ever bought with my own money. I bought it as a package with a rtty decoder and software. I wish I still had that setup.
btw, the first computer that the family had was a Video Genie Model 1. My cousin had a TRS-80 and we were going to get one of those but my dad saw an ad for the Video Genie and decided it was better value.
in 1982, about 350
