Color Computer 2

Released in 1983, the Color Computer 2 was a sleeker, more cost-efficient revision of the original CoCo 1. Built around the same powerful Motorola 6809E CPU, the CoCo 2 offered expanded RAM options, an improved keyboard, and a compact, durable white case. It retained full compatibility with CoCo 1 software and peripherals while providing a cleaner user experience and better build quality. The system remained a favorite for BASIC programming, educational software, and home gaming until it was eventually succeeded by the CoCo 3 in 1986.

Notable Features

• Improved keyboard and internal shielding over CoCo 1
• More robust and efficient power supply and motherboard design
• Fully backward compatible with all CoCo 1 software and accessories
• White case gave it a more modern aesthetic, matching other early '80s home systems
• Widely supported by Radio Shack stores, third-party developers, and hobbyist magazines

Historical Significance

• Helped popularize the 6809 CPU among home programmers
• Expanded Radio Shack’s user base with a more reliable and attractive design
• Remained a popular educational and hobbyist platform even after IBM PC dominance began
• Set the stage for the Color Computer 3 with standardized expansion paths and software libraries

Collector's Notes

• Rarity: Low to moderate – fairly common but early variants and boxed units are collectible
• Desirability: High among 6809 enthusiasts and BASIC programmers
• Common Issues:
  • Slight RF interference issues on aging units
  • Failing cassette interface or worn cartridge port
  • Keyboard key bounce (on early models)
• Display Tips: Great to show booted to Extended BASIC or playing arcade-style ports like Donkey King or Buzzard Bait
