The document provides a brief history of early personal computers, beginning with the Altair 8800 in 1975, which was one of the first commercially available personal computers costing $395-$498. It had 256 bytes of memory and attracted many programmers and hackers. In 1976, Steve Wozniak and Steve Jobs built their first computer called the Apple I in Wozniak's garage, which resembled a typewriter in a box and was one of the first to include a keyboard. They later went on to form Apple Computer Co.
