The TRS-80 Color Computer, or CoCo, is sometimes left out of the discussion of great 8-bit home computers despite its popularity. Tandy sold millions of them through its network of Radio Shack stores, but a strong retail channel was not the only reason for its success.
The CoCo was a strong performing, inexpensive computer with a solid base of software. Its powerful 6809 processor and support chips enabled color video before many competitors. With the later option of the OS-9 operating system and expanded memory, the CoCo was also a viable development or business system.
The photo here shows a first-generation CoCo, apparently in a law office. Though most CoCos were sold as family computers or to hobbyists, some small businesses did use them and there was enough of a software base to support business use.
