Known to it's fans as the “CoCo” or “80C”, the Tandy / Radio Shack Color Computer was the first micro-computer I owned.
In the past 40 years (!) a huge 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.
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.
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 me and hundreds of other “CoConuts” (or is that CoConauts?) on the CoCo Discord.
New to Discord? Get started quickly with this video introduction.
