The Apple I was one of the first personal computers, designed and hand-built by Steve Wozniak in 1976. It was sold as a motherboard, meaning users had to provide their own keyboard and monitor. The computer featured a 1 MHz processor and came with 4 KB of RAM, which could be expanded to 8 KB. The Apple I was notable for its simplicity and affordability, priced at $666.66. It played a crucial role in the founding of Apple Inc., alongside Steve Jobs, who helped market the product. Only about 200 units were produced, making it a rare collector's item today.
