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.
