Color? That'd be the TRS-80 Color Computer, very different from the TRS-80 Model III, which was a (slightly) improved version of the TRS-80 Model I. Different CPU (6809E) in the CoCo, most of the TRS-80s used Z-80s till you got to the Unix machine, which used a 68000. Didn't appreciate the CoCo at the time, but a neat machine in retrospect.
