The Apple II, also known as the Apple ][, was an 8-bit home computer released by Apple on June 10, 1977. It was designed by Steve Wozniak in conjunction with Steve Jobs. The standard model cost $1,298.
The Apple II had a 1 MHz CPU and 4 kilobytes of RAM (random-access memory). The BASIC programming language was built in one of the computer's ROMs (read-only memory), allowing users to write their own computer programs. It used NTSC (National Television System Committee) graphics output, capable of displaying on a standard TV monitor. It displayed text in monochrome and only uppercase letters, using 40 characters per line and 24 lines per screen. It also had low and high-resolution graphics modes, which could display color.
