Affectionately referred to as the "bread box," the Commodore 64 is the best-selling personal computer of all time. Estimates put sales of the C64 at more than 17 million. The 8-bit computer hit the market in 1982 for $595 and shipped with a 1.023-MHz processor, 64 KB of RAM and 16-color graphics, and it could easily be hooked up to your home television.
