The Commodore VIC<\/a>-20 holds a unique place in computing history: it was the <\/span>first home computer to sell one million units, arriving in 1980 at a retail price of USD 299.95 \u2014 roughly half the cost of any comparable machine at launch. What most hardware enthusiasts and retro-computing collectors do not realize is that the VIC-20 was not a single, static design. It went through multiple board revisions, and the <\/span>VIC-20CR represents the final and most refined iteration of the platform, manufactured from approximately 1983 until the model\u2019s discontinuation in 1985. Understanding the CR variant requires understanding both the machine\u2019s engineering history and the cost-reduction logic that drove Commodore\u2019s manufacturing decisions throughout the early 1980s.<\/span><\/p>\n
