Built in 1977, the Apple II was based on Wozniak's Apple I design, but with several additions. The first was the design of a plastic case--a rarity at the time--which was painted beige. The second was the ability to display color graphics--a holy grail in the industry. The Apple II also included a larger ROM, more expandable RAM (4K to start), and 8 expansion slots. It had integer BASIC hard-coded on the ROM for easier programming, and included two game paddles and a demo cassette for $1,298. In early 1978 Apple also released a disk drive for the machine, one of the most inexpensive available. The Apple II remained on the Apple product list until 1980.
