Color Computer 3

Introduction

The Color Computer 3 (often called the CoCo 3) was one of my first computers and holds a special place in my computing journey. Released by Tandy Corporation in 1986, this 8-bit home computer was part of the Tandy Color Computer series sold at RadioShack stores.

Technical Specifications

The CoCo 3 was a significant upgrade from its predecessors with:

• Motorola 6809E processor running at 0.89 MHz or 1.78 MHz
• Up to 512KB of RAM (a huge amount for the time)
• Enhanced graphics capabilities with resolutions up to 640x225 in 4 colors or 320x225 in 16 colors
• OS-9 Level 2 operating system option, which provided a Unix-like environment

Personal Experience

I spent countless hours exploring the capabilities of this machine, learning BASIC programming, and playing games. The CoCo 3’s ability to run OS-9 Level 2 was particularly fascinating as it introduced me to concepts like multitasking and a hierarchical file system long before these became commonplace in home computing.

The green text on black background interface of OS-9 was my first introduction to command-line computing, teaching me valuable skills that would serve me throughout my career in technology.

Historical Importance

The Color Computer series, and particularly the CoCo 3, represented an important chapter in home computing history. It was part of the first wave of affordable color-capable home computers that brought computing into everyday households.

While it may not have achieved the fame of contemporaries like the Commodore 64 or Apple II, the CoCo 3 had a dedicated community of users and developers who pushed the machine to its limits and beyond.

Legacy

The skills and knowledge I gained from my time with the Color Computer 3 laid the foundation for my future in computing. From basic programming concepts to understanding file systems and operating system environments, my CoCo 3 experience was instrumental in sparking my interest in technology.
