Introducing the CoCo

Known to it's fans as the “CoCo” or “80C”, the Tandy / Radio Shack Color Computer was the first micro-computer I owned.

The “Color Computer” family of computers includes the Color Computer, Color Computer 2, Color Computer 3, Dragon 32, Dragon 64, the Micro Color Computer (MC-10), and a number of clones such as the CP400, Codimex 6809, and many more.

In the past 40-plus years (!) a fantastic community has grown up around these machines, continuously refining and expanding the hardware, the software, and the boundaries of what these early microcomputers can do.

Getting Started


Don't have a Color Computer yourself?
CoCo-Pi will turn a Raspberry Pi 3, Pi 4, or Pi 400 into a feature packed Color Computer emulation workhorse to enjoy 40 years of Color Computer awesomeness.

Quick Start: A quick description of various ways to load software into the CoCo.

Getting Connected

Join hundreds of “CoConuts” (or is that CoConauts?) on the CoCo Discord.
