The Dragon 32 (and Dragon 64) were British microcomputers from the early 1980s that had a lot in common with the Tandy "CoCo" Color Computers. Not technically a clone but often compatible.
We only have a couple of questions specifically about the Dragons, and a few more that mention them.
Should we wait until we have more questions on them before creating a tag, add the existing CoCo tag to questions about them, or just go ahead and make one now?
