The Radio Shack TRS-80 Color Computer, also known as the Tandy Color Computer or simply the Coco was a line of home computers produced from 1980 until 1991. It was the only common computer I am aware of that used the Motorola 6809 CPU. This was an 8-bit CPU but had some 16-bit features and was powerful for its time.
There were three interations of the Color Computer with various features and improvements but for the most part they maintained backwards compatiability in terms of software. Some add-on hardware also maintained compatability across iterations.
There weren't very many magazines that covered the CoCo relative to other popular machines at the time but The Color Computer Magazine was one such magazine dedicated to this machine.
The November 1983 issue included the following:

The Coco wasn't really as popular as Commodore, Apple or Atari computers but it was supported by Radio Shack for a long time and still had a magazine or two dedicated to it, including Color Computer Magazine.
The November 1983 issue included the following:
Features
-
- Super Spiro! – A type-in program for generating spirographs, including parameters for several different ones.
-
- Color Computing for Kids – A programming article for kids. Included is a tutorial on FOR/NEXT loops in BASIC with math examples and an example printing a Thanksgiving message.
-
- Star – A simple type-in program for drawing a star-like object on the screen.
-
- Sorcerer’s Puzzles – A type-in game that features several puzzle challenges.
-
- Slither – A type-in machine language game. This game existed on may computers in many forms. You control a snake as it goes around the screen eating things. As it eats it grows longer. If you run into yourself, you die.
- Unforgettable Characters – Creating custom characters on the Color Computer.
-
- My MC-10 Speaks ML! – The MC-10 was a sort of cut down version of the Color Computer designed to compete with even cheaper computers like the VIC-20. Other than BASIC programs, it was mostly incompatible with the Color Computer and far more limited. It was not a success. This article covers machine language programming on that machine.
-
- Custom Color – Despite the name, this is actually an article about music and sound on the Color Computer and computers in general.
-
- One-finger Hexload – A program that allows you to enter hex numbers without prefixing them with '&H' which was normal procedure on the Color Computer. Useful, for example, for typing in machine language programs.
- Graphics? Yes! Part II – Draw lines and circles - A tutorial for creating graphics in BASIC, including examples. This month the focus is on drawing lines and circles.
