-20) An early personal computer from Commodore Business Machines. Introduced in 1980 and following the Commodore PET, the VIC-20 had 5KB of RAM, used tape cassette storage and displayed 22 text characters per line on a standard TV. With a price tag of $300, it was the best-selling personal computer in 1982 and the first computer to achieve sales of one million units. Its successor, the Commodore 64, looked just like the VIC-20, except it was beige instead of white. See
